Not Again!

[180sxdrifterj]

im having fun with this car.. just ordered a TD05 and PFC and now more problems happen..

driving along(car is a Type M R32 GTST btw), and was at the lights.. in first, took off normally, jumped into second and the car started jumping. didnt hear any crunching or weird noises from box/clutch, more like it was ECU?

basically, its like ive lost all boost!

i would get to 2500-3500 before the car would jump and idle weird... normal idle went from 700 to about 1300rpm... i would have to go from first to second, and stay below 2500rpm to be able to drive it back..

any ideas what this could be? :S i want this fixed before GOR!!

its a standard Type M R32 manual gearbox, wtih nismo short shifter.. thats it... only other mod ive done recently was front mount but i checked the piping and it all seems alright?

just checked the radiator while car was on (car now sits there and idles from 700, and slowly SLOWLY VERY SLOWLY goes up and sits on 2000rpm), and there are bubbles?

gasket?

check your afm is plugged in properly and hasn't come loose

Check under the oil cap to see if the oil is milky.

Also check the water in the radiator to see if its oily.

Check the dipstick also, see how the oil level is, and how good the oil looks.

Is it over heating at all?

afm....

my old 32 did that, it was a dodgey afm

the first set of issues sounds just like AFM... could be dirty or need resoldering. if you have someone with the same one, borrow to test, else search the forum for +solder +AFM. i just did mine its not hard.

bubbles in the radiator liquid could just be some air escaping the system.. did you replace your coolant recently ? does the car lose water ?

my car does this.. lol i just put a thread up about it woops.

Maybe fuel pump? This happened in my r33 and it was the fuel pump.

Don't think a dying fuel pump will make too much variance on idle. In my past experience a dying fuel pump makes the car slightly hard to start, hesitates in the rev range and also pings if its turbo.

The more you think about it, the more it sounds like an AFM issue.

Sounds like it could be a head gasket mate

Not the best if it is...

time to have a little play right now.. i hope it is AFM... we are going to clean the air flow metre, and check all hoses and piping... if its a dodgy afm, no loss, im getting a Z32 ive been persuaded that its air flow metre/piping so ill see how it goes and get back to you

hey, i had the same problem with my r33 s2,

after i just got my apexi neo afc fitted, 2 days after it did the same thing as u described!!!

i had to reset the afc to drive..and it was fine..

went to the tuners 2 days later, found out my 02 sensor was dying, or dead already..lol

needed a new one..and has bein fine ever since...

so try disconnecting the 02 sensor..

and c if it makes a difference..

but i think my afm is on its way out having trouble starting wen cold..bein cold latly for the last 2 days, and my car struggles only wen very cold..i think either to do wit my afm, or im to lean for idle..lol

but i cleaned my acc valve the other week..look lik brand new inside..and idle has bein really really good..

i cleaned my afm, wit electical contact cleaner,looks cleaner

and i cleaned my acc valve wit carby cleaner..and keep on wiping in it! takes a while..but makes a hell of a diff.!!

so try doing these, and check ur o2 sensor too...

This exact same thing happened to me on sunday night. I had just put a 3" cat back on and was going for a spin (my pc had just broken to zzz)and the car started stalling and playing up so i pulled over and fiddled with the AFM wires until the idle returned to normal (i had just put on pod filters) i also had what looked like froth coming out of the radiator (as opposed to bubbles) but the car wasn't overheating and was dead on center

Only problem with mine is now it's making a noise (not overly loud, probably about as loud as the injectors but a bit less harsh), screw driver indicates it's coming from the head, so idk what happened but i'm guessing when the AFM frigged up it over stressed something and something broke or was badly worn (it still drives ok)

Just my luck, 5 days till i can finally drive it and it farks up along with the pc and the job i quit on friday ._.

Thats your car going into R&R mode (limp mode) so you can drive it home without detonating the engine. You'll need to reset the ECU and do a self-test diagnostic, this will tell u whats broken i.e. as above 02 sensor etc.

I believe
