Hi all,
I've got a problem with my Mk4 2002 Golf GTI (2.0l 8v 115bhp). Its beggining to be a real pain at starting in the morning, saying that after taking it for a long run, turning the engine off and starting it again 10mins later, its struggles to start. If i turn it on without tapping the pedal, it either struggles to start or fails completely. The times it does start with a struggle, the rev counter is low, about 500rpm and is chugging, then after about a second or so the engine jumps into life and rev counter goes straight up to about 1100 rpm and slowly goes back to normal idle rpms as the engine warms. It has never cut out, missed a beat or anything once started, its just the inital starting. When i start it and have to put my foot down on the gas it makes the starter motor whine, so i really want to fix this problem before i break the starter motor aswell. I've been told it could be the HT leads, the air flow meter, etc........ I've already had new platinum spark plugs fitted, which made no difference. It does however seem less of a problem in the summer time.
Any help in norrowing the problem down would be great.
On a slightly different note, there is also a strange noise coming from the front of the car, i think, not sure as it only happens when driving. When i change gear and then re-apply the gas with a little more grunt than normal it makes a metalic knocking noise, only one knock tho and it seems to happen on a 50/50 basis. From 1st to 2nd gear is louder than say 4th to 5th, but while in gear if the car is reved high and then released, still no gear change, then reved again it will make the noise. Is this just something loose? A baffle in the exhaust maybe?
Any light shed on these would be great, thanks alot ppl, keep up the good work.
