Black_CSR Posted April 3, 2010 Share Posted April 3, 2010 Hi guys i'm having some Issues wif my line. First of all i was driving it along one day and it was fine. Then next time i drove and started it up a lot of black smoke came out and it was running really rich and idle was was not very good. If you rev it would go down instead of going up. It's not drivable as it would splutter and chugga chugga chugga Big Red Car... hehe.. Sounds like it's got really Lumpy Cams and is dropping out. I cleaned out the plugs and tested all my splitfire coilpacks and they are fine. Not sure what it is though.. Mod list are PowerFC 2530 .84 A/R Hi Flow spec Turbo Stock AFM Stock Injectors Bosch 910 Pump HKS EVC 5 Hmm that is all i can think of that it's important. I don't understand it all as it was running perfectly and now it's... Link to comment https://www.sau.com.au/forums/topic/315053-limp-mode/ Share on other sites More sharing options...

alpinestars Posted April 4, 2010 Share Posted April 4, 2010 see if you can get another afm off another member to borrow to diagnose the problem Link to comment https://www.sau.com.au/forums/topic/315053-limp-mode/#findComment-5164193 Share on other sites More sharing options...
d1_drifter Posted April 4, 2010 Share Posted April 4, 2010 Unplug your AFM and see if it still idles like that. If it idles fine with it unplugged, it's your AFM. Link to comment https://www.sau.com.au/forums/topic/315053-limp-mode/#findComment-5164284 Share on other sites More sharing options...
DR1FT4 Posted April 4, 2010 Share Posted April 4, 2010 If you have a d-jerto PFC then the afm wouldn't affect the idle like that, but if its not then yeah sounds like the afm, just give it a spray with some contact cleaner, and if that doesnt help then yeah ask another member to borrow theirs to help diagnose the problem, i wont mind you using mine just im not able to get back till wednesday, but give that a try to start with Link to comment https://www.sau.com.au/forums/topic/315053-limp-mode/#findComment-5164298 Share on other sites More sharing options...

Ashy Larry Posted April 4, 2010 Share Posted April 4, 2010 Check the connectors leading onto the injectors, been here before.... Car will run on 5 cylinders and sound rough as. Just got 1 at a time too see which one if not firing. Link to comment https://www.sau.com.au/forums/topic/315053-limp-mode/#findComment-5164492 Share on other sites More sharing options...
Nic_A31 Posted April 4, 2010 Share Posted April 4, 2010 Engine should run without the AFM connected. The RB20 in my Ceffy used to, the VG30 in my Maxima does too. As soon as you open the throttle it'll die as it's injected 'idle rpm' worth of fuel to a higher amount of air and can't combust.

R32 Driver Posted April 5, 2010 Share Posted April 5, 2010 Connectors leading to the Injectors is fine.. they haven't been touched at all.

Flash89 Posted April 5, 2010 Share Posted April 5, 2010 i dont think powerfc has limb mode that prob why it stalled with the afm unplugged. just try borrow another rb25 afm. also did you put the filter back on when you cleaned out the afm. afm dont like it when there isnt a filter.

Black_CSR Posted April 9, 2010 Author Share Posted April 9, 2010 (edited) Ok Update... it seem to have gotten worse.. it's running on 2 cylinders now.. doesn't make sense how i'd lose 4 cylinders all of a sudden... Goin 2 possibly check the loom for the Coilpacks.. if i do have to replace it?? how much do u reckon it will cost? Gonna possibly tow it to the workshop that installed my new turbo 1 week ago so they can do further diagnostic...

Black_CSR Posted April 10, 2010 Author Share Posted April 10, 2010 Ok all the wires leading to the Coilpack is fine.. and Fuel pump intank & internal is fine as well.. Haven't checked wires leading to Injectors... I'm thinking it might be Computer related.

Black_CSR Posted April 11, 2010 Author Share Posted April 11, 2010 (edited) Ok another Update.. Replaced all the Plugs and it's running on all 6 cylinders again.. still idling rough and lots of black smoke n running rich.. i guess it fouled the plugs pretty quickly running rich?? Goin 2 burrow off an AFM from a friend and see how that works.. Do u guys know th resistance value readings of the AFM on it's 3 pins? I'm gonna use a Multimeter and check the readings..
