took the car (sti type r )to cardiff airport to go on holidays, was fine going and left it there a week.got back late friday jumped in the car tried to start it and the check light came on and it cut out it did this several times then it started running so of we went. when it warmed the check engine light went out, but it was missing a bit and there seemed to be no boost from the turbo. got home about 30 miles got up next morning and it's back on now with the same symtoms,very irratic idle, ok then from 1000rpm to 4000rpm with very little boost then from 4000rpm on it misses and pops and bangs!
any idea's?

looks like a genral problem.it all to do with the sensors just have to work out what one is playing up

 

not sure if you no this ,but there is a way that when the engine cheak lights on .(im not sure some one on here will )you have to do something an it will flash on and off so many times depending on the fault the codes were posted on here not so long ago hope this helps

 

CEL flashes and you can get the code, then do a search for the flashes, the one i know ohh so well is 3,2 =Lambda sensor.

to get this connect the two wires under the steering wheel, the CEL flashes and take the code, then do a search on here for cel error codes.

hope this helps.

 

done a code check and the cel flashes in this way two one second flashes followed by three half second flashes. i think it's the maf sensor

 

The symptoms would suggest a failing MAF sensor, but that is only an educated guess.

I'd get it to someone who knows what they're doing sooner rather than later.

 

it was the maf should have it back today

 

i found this thread very interesting because my light came on just once very breilfy on a journey in the rain on sunday on the m40....I thought wot the hell was that....now i have some idea of what it could be and will keep an eye on it. It hasnt happened since.
My car is 3 and half years old...do sensors begin to fail at that age. I have done 35 k miles and always run on optimax.

 

had to take it to bristol about 50 miles from where i live the light went out a few times on the way but it still had the fault. you can tell trust me,tick over all over the place and no boost and would not rev over 4 thou. safe mode i think

 

So it wasnt the maf then? who said it was?
