hey guys,

so during a normal midday drive i noticed my car cutting fuel or ignition when reaching 2500-3000rpms. the problem increased with every 10min or so. now when i start it up it idles really low prob about 400-500rpms and looks like it running on 4 or 5 cylinders only with black smoke coming out the exhaust. I've checked the maf sensor, cleaned it out, put it back but I've notices a better idle without this maf sensor plugged . i did try 2 other maf sensors and it reacts exactly the same as when i plug mines in. not able to drive it with a maf plugged in and even stalles and lots of misfires. i would appreciate any help or advice on what may be the cause of this problem. thanks in advance guys.

Sounds like its going into limp mode, have you tried pulling the diagnostic codes from the ECU? could also be a leak under boost.

 

[dave87]

no i did not read the ecu.. and yes it looks like limp mode but where should i start looking?

Coil packs imo

it could be one of the coil packs as i already changed one earlier so im gonna check in that tomorrow. if there is any other suggestions id be more than happy to hear them. thanks for the advice guys.
