Hi All,
I've not had my car very long, it's a 1996 Mk3 Golf GTI 8V (AGG engine with Simos injection) but it's got a little bug that's annoying me.
When idling the car seems to miss, but not a really rough miss like an ignition problem. It seems more like a mixture issue...It happens not only at idle but when the engine is running at steady revs and not under load. So I could be coasting along at 30mph in third and holding the car at that speed and it chugs like it is missing. The car accelerates super smoothly and deceleration is fine too.
I had already changed the plugs and leads which made no difference anyway and the car has just been in for an 80,000mi service where in addition to cambelt and filters I changed the coolant temp sensor and oil breather tube with no effect on my problem.
I've checked all the other intake plumbing which seems to be in good condition and sealing well.
Has anyone else had a similar problem? I'm thinking i'll go along the way ov changing the Lambda sensor and then the air flow meter if it comes to it...
Any input is appreciated, thanks
Trent
