Hey guys, drove around today with no problems, but on my way back home, sounded initially like i had a flat tire, then realized was the engine.

Car sounds like a wrx (which isn't normal lol), if i'm rolling along, the engine will stutter, especially when accelerating. When travelling along, the engine will slow down then burst forward for a sec, then back down etc.

Got a booking fr Trojan on Thursday, but its a 40-50 min drive from my place, and seemed to be getting worse on the 10 min drive to my place.

Any idea what it could be? Just wondering if I should drive it on Thursday, or get it looked at by someplace close perhaps tomorrow or tuesday first.

The only weird thing I can think that happened, was yesterday, my nan was watering the garden and somehow lost the hose, went under the car and drenched the engine bay from underneath. I noticed the pod filter was a bit wet but left it overnight/day to dry and like i said, it ran fine......

If you haven't guessed, i know next to nothing about this stuff...

If your pod filter's wet then it's very likely that you've gotten your airflow meter wet. Could be that. It could also be the electrical contact for the crank angle sensor has gotten wet, which isn't far from the air filter.

Could be your coilpacks starting to bomb out by coincidence, but that only really happens when you rev/boost it hard and flat footed (initially).

Does it matter if the engine's warm or not?

Thanks mate,

Nah dosn't matter if the engine is warm, drove home which was like 15-20 min drive, did it the whole way

Should mention that my engine is stock. just got the pod and zorst.

my silvia (RB20) sounded like a wrx when running on 5 cylinders on idle but as soon as you started driving itd run on 6 cyls. possibly coils. just get some splitfires and see what happens.

could it be the spark plugs not firing right

I'm not sure, that was my initial thoughts. Hmmmm...... Might drive it to my local place, see whats wrong, if they gotta replace stuff i would prefer trojan to do it - except not really wanting to drive it all the way there lol.

.......or depending if you can get it to do it at idle

easy way to test the coils is by unplugging them one at a time. whichever one doesn't make a difference.... will have some issue with it.

man i had the exactly same issues here. my RB25de Neo have some trouble with missfiring. because it sounds like a WRX. probably chilling winter in canberra?

if u start the car in the morning (or when the engine is cold) it sounds ok for 5 minutes (because the car automatically retard the firing). after 5 mins the timing gets advanced to normal state, thats when the engine sounds like WRX.

i'm opening my intake plenum now and will open the cover tomorrow to check and replace the spark plugs / coils / looms. or even injectors.

if u'll bring it to local workshop, will u share the answers with me?

cheers.

One thing he's forgotten to tell you though don't unplug them/plug them in while the car's running... right James? :D

OMG TOOK THE SPARK PLUGS OUT WHILE IT WAS RUNNING AND THE ENGINE WON"T START NOW>.......

just kidding ;-)

Thanks guys, getting it towed to trojan tomorrow. gtrkat, your price was spot on! Thanks!

Trojan thinks it could be the spark plugs or coil packs ;-)

Will see on wed/thurs. Hopefully won't break my bank account...fingers crossed!

Good luck mate, i had an issue with mine not long ago where it would just stop accelerating all together, then it'd kick back in and cut back out, all within the space of a few seconds. Took it to Ed at AutoTech and it turned out to be the solder on the wires in the AFM had come loose and were barely making contact causing the PowerFC to think there was no airflow coming in and cutting the power. To make matters worse had a grounding issue at the same time and one problem masked the other.

    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
    • So, a bit of a side trip, but one that might be interesting for people with JDM cars and japanese head units. I know @Pac previously posted about a carplay/android auto adapter he installed which used the AUX input, and @V35_Paul put in one of the Tesla style units that replace both screens. The option I went with was a Lsait LLT-YF-VER5.87_2 (https://www.alibaba.com/product-detail/Lsailt-8GB-Android-Multimedia-Interface-for_1601187633672.html). Price was $1,150 for a single unit although they are much cheaper if you are willing to buy 2....$857ea. Make you you get the version 2 not version 1, it is faster and has a better UI - this is the manufacturer listing: http://www.lsailt.com/product/348.html. BTW if you've never bought from Alibaba before, don't be concerned....these guys can't stay in business unless they are responsive, ship fast etc, they were excellent (probably faster shipping than most local places) So, this was my task for a lazy Sat afternoon....looks complex but was all done in a few hours (it probably helps that I had some of it apart before so it was a bit familiar). I also decided to add a HD USB drive recorded at the same time and the unit also supports an aftermarket reverse cam (if you don't want to retain factory) and also AV in and HDMI out It looks much worse than it is, in fact in was genuinely all plug and play (no custom wiring at all). This video was pretty good (skipped a few steps), unfortunately they are an Aussie seller but no longer sell this unit (I guess Carplay/AA adapters are easier to install and much cheaper) https://www.youtube.com/watch?v=T5hJfYOB8Dg
