Okay guys (and gals),

Car is not running properly still !!

I have changed all the coilpacks and spark plugs and that was the original suggestion when I last posted.

When accelerating hard, it starts to feel like it is being held back at around 3-4k (more noticable in 3rd 4th gear).

The car has always thrown up the cam (?) position sensor code up, and I have noticed that it runs particulary bad when the CEL is on .... Any ideas ?

Thanks in advance

 

what car is it mate have u looked at he maf sensor?

 

I haven't, but I have been told that is probably not the MAF sensor ....

Don't know how to check if it is okay either

 

Forgot to say ...... It's a MY01 WRX, running STi Pinks, VF28 and STi Top mount .... Obviouly with all the other gubbins to go with it.

 

Anyone ?

 

Is your DV leaking ? Might be worth bunging the old one back on, or checking the gasket.

 

to check ya maf just start the car and the disconnect it the car should just stall if all is OK m8, if not its fected . if so try to clean it with ONLY electrical cleaner as wd40 are simmiler is oil based and will leave residue . hope this help you regards dave

 

mate my bug has had the same problem for the past couple of weeks iv done the same changed the coilpacks changed the plugs still the engine light flashes on now then wiv a missfire iv also recently fitted a new BOV so i dout its that and iv cleaned the maf still does it n apparently the cam sensor is (from the factory) slightyly 2 far away from the pickup on the cam so when u giv it beans it goes out of range n brings the light on.... the only other things on the system is the wiring and the ECU not so good... i thought id sorted it wiv the plugs but 2 weeks later the Ba&$*rd light came back on , if urs is like mine it only does it now n then n it normaly brings the light on when u hav sum **** dickin around behind u lol... if u get it sorted drop me a message please lol il do the same...

 

Wild card suggestion, but bugs have particularly bad earthing for some reason. Try anb earthing kit. I have regularly heard the phrase 'random fault code generator' used to describe a bug ECU, possibly because of this alleged earthing issue

 

its so tempremental i just took mine for a spin n soon as she was warmed up it was flyin!!! its a MyStErY!!!!!

 

Mine is exactly the same, I have a front lambda sensor fault code that keeps on reappearing. Out playing in the searing heat 2 weeks ago and not a peep, ran like a dream.

Last weekend and this weekend drove up to Lincoln and back. On the way there nothing for 90 miles, get to the twisties and have a play and it lights up. Reset it and no more problems. On the way home, cruising down the A1 and it comes on after 50 miles, reset it and all is fine all the way home.

Headers are coming off to be replaced with some ported and wrapped ones so I'll look at it properly then, but it is so annoying (and random)
