I am nearly at breaking point! Some of you would have read my last thread Help Damn s16, when I explained how my s16 was running extremely rough, using heaps of fuel etc.
My question now is, one of the intake diaphrams is not functioning, this is causing the usual extreme lack of power above 3500 rpm, but will this also cause it to idle very rough nearly sounding like a rotar, then when I accelerate it is missing right through the rev range (sounding like a boxer engine).
In my last post I mentioned I have had a full ECU scan, replaced the O2 sensor, then rescanned,no more faults. So I have then replaced all coil packs and spark plugs. Still running badly. Took the car to Kent Town Auto Tune as reccomended by Charles St Auto and left it there for a few days. They hit me with a whopping bill an the car is running worse than when I took it there. They cleaned the injectors and didn't find any improvement from that. They checked fuel flow it was 1.4lt/min. seems ok. The emmissions were fine, as was the back pressure from the exhaust! They reckon its running on all 4 cylinders??
Im so frustrated as I have spend over $1500 in the last month trying to get the car running well but no one can fix it properly!
Any more suggestions would be greatly appreciated!
