Not sure to post this here or under engine but as everything is electronic these days I thought I'd drop it here (so apologies if its in the wrong place).
Right, got the car back from the body shop the other week after having the front end built up and painted after an accident by previous owner. Car runs fine, no engine light or caution lights come on but after around 10 - 15 seconds from starting the car the engine begins to hunt up and down. It goes from around 2k to 3k and will do this all day if I left it, even whan the car has got upto temp (10 minutes running) it will still be reving itself upto 3k and down again.
I have a feeling it might be the oxygen/lamda sensor but have no way at the moment of getting it to a dealer for them to plug in and have a look(as I'm waiting for the windscreen to be replaced then hopefully take it to get mot'd), so waiting for a mate who's an auto electrician to have a look (which I've been waiting 2 weeks for:O( ).
Also, I noticed that if while it's running I put my foot on the gas it only lets me rev it upto 4k and no more (like a limiter!!)
I have also taken the idle control valve out and cleaned, altho it did look pretty clean anyway, but same fault remains.
I know this may seem like a vague description but was hoping someone else outhere may have heard or had the same problem and can point me in the right direction while I wait for the auto electrician to pull his finger out.
Many thanks in advance folks, Brian.
