CHECK ENGINE AT 140mph


Recommended Posts

Posted
I have a MY00 UK impreza turbo and i hit 140 mph but when i did the CHECK ENGINE light came on, i s**t myself and immediately let off the throttle but as i did the light went off and hasn't been on since.  The car is also running fine, any ideas would be much appreciated??

Is the car still standard?

If you still have a top mounted intercooler they have been known to cause problems at high speeds. The air that is normally forced through the scoop gets blasted over it instead and you can suffer with high charge temp's causing det.

Don't know if this can cause a flash of the CEL on a standard ecu but certainly can on the Apexi PFC ecu.

aye the car is still standard, but want to modify it asap!  What are a good list of mods that'll see me close to 300 BHP?

ive had the same thing happen twice on my 05 sti, garage had a look at it and said it was dirt going through the waste gate.

great things test tracks arent they[;)]

what are you doing driving at 140mph anyhow

are you not one for 'givin it ping?'

All for giving it ping but admiting to it on a public website is not the best idea.

The polis have been known to read this forum

That is why all speed referneces also have "Proving ground" or "test track" contained in the post

No it went off the clock after that, would love to know what speed i was actually doing because your speedo isnt very accurate at those speeds.

I'm impressed, what model is it and what mods you got?  What kinda bhp is it?

Loving the Pic.... [:D]  I saw 135 while on a test track in my 99 UK Turbo while Mr oil pump decided not to work over time in the process.
