Bugeye Check Engine Light - erratic revs
Morning all.
So got back to the airport carpark after a week's holiday in the sun - picked the car up and drove it to the exit - all OK.
Pulled out onto the roundabout and the car was very juddery in first - almost like poor clutch control, this happened until I shifted to 2nd. Then looking down the engine check light had come on, and the revs felt very "bouncy"
Pulled over 200yrds down the road and in neutral, touching no pedals, the revs were hunting up and down between 1k and 2k. even when warmed up.
RAC chap duely comes out, revs it a bit and it settles down but a quick test drive felt really rough so stopped again.
He seemed to think that it could be a faulty sparkplug and/or coilpack or HT leads. but given it was silly-o-clock at night he didn't have the tools to check the boxer engine or get to the plugs!. Car got recovered and I'm waiting for it to be delivered in the next few days to the garage.
Any ideas what it could be?
Also, when driving it onto the back of the pickup, there was some definate clutch smell - could just have been my technique getting it onto the big slope however...
car is a MY02 bugeye STI, standard apart from dump valve (I didn't put it on ) and a Powerflow exhaust (with cat, and a bung)
Cheers
Ben

you have to connect the 2 wires under the dash and it will give you the fault code you read them like mores code dot/dash count the slow pulse for first number then the fast pulse and for the second number and you will have the code you need

Speedking: Yes it was - I think I've been having some handbrake sticking issues - but Paul at extremescoobies took it apart - looks Ok but very worn.

Ah, no worries - it's being directly recovered to the garage tomorrow (C&D Motors in Cambridge if anyone know them, have done some good work on my other cars).
They should be able to take a look, but fingers crossed it's just plugs/leads/coilpack or some such. I've only had it for 8k miles so would be a bit of a downer if it were compression issues or such

Sticky iac valve, remove the valve from the throttle body (you will need a new gasket), take the valve apart and your probably find the shaft is not spinning freely, soak it in petrol to clean it right up, then lubricate the bearing and put it back together and on the car, fingers crossed it will be ok......just had this on my 2002 bug.

I know this sounds really **** of me. But I just bought a new one. I think it was the motor itself that packed up on mine.
Wasn't cheap.
You think thats bad. Wait till you see how much a MAP sensor is!!!!

Typically the car came off the back of the transporter and into the garage with no problems and no ECL on it
They've read the ECU logs and it indicates that the ICV was sticking - so they are going to pull it out, clean it up and let me know.
Here's hoping!

Providing the screws undo(which can be a problem the first time the removed) > the heads on the o/e screws are very soft, I replaced mine with stainless. Takes 10 mins ish to remove a good clean another 10 or 15 then 10 to replace

Best way to remove the screws is put a 8mm flat screw driver in the screw. Give it a few taps and then put a 8mm on the end of a small ratchet and give it a go.
You will need a new gasket.
Replacement screws and sizes are M5 x 20mm Hex Screw heads.
Job done.

Just got the car back from the garage. ICV all cleaned out and the ECU cleared and showing no codes after a test drive.
Charged me 1hr labour, which I thought was fair.
