Engine Light On

[markdem]

my stageas engine light comes on and the car hesitates and runs rough between 1000-2000rpm. today it got really bad and the revs started dropping and then picking up again a lot before finally stalling. i did a diagnostic check on it by bridging the 2 connections on the diagnostic port and i got code 55 - all cear. WTF.

ive cleaned the AFM, swapped the coils, replaced the sparks, cleaned the AAC valve and filled up with 98 premium

the previous owner put an aftermarket exhaust on it and has cut the connection to the o2 sensor after the cat (there isnt a sensor to plug it into). the rest of the car is bog stock. not even a pod filter

update. i checked the codes a few minutes later. code 12; AFM.

Take the top off and get out your soldering iron.

It is a pretty easy fix even if you are a nuff nuff like me with soldering.

Check the wiring around the plug carefully too while you are at it.

Is it fixed now??? I have a spare unit that needs soldering so want to know if it worked for you???

not getting any more AFM fault codes but the car is far from fixed. still doing the weird stalling thing between 1-2rpm but i went to japanese parts n performance in molendinar and got another AFM just to make sure. same shit happening between 1-2rpm

so to answer your question; i THINK it fixed the AFM..... :S

You sure its not got a vac leak? There is the AAC too.

could be a vac leak. i still need to test that. already cleaned the aac valve
