Losing Power And Engine Light On

wiggy1 · February 5, 2008

Anyone ever suffer with this problem? Basically when i hit the 120kph+ mark my engine light flickers and ive no accelerating power. If i drive at anything less than this speed it is perfect. From take off its normal, there is no power loss and it flies up through the revs without missing a beat. Its just when i hit 120+ it goes bad. Its only started doing this since having some work done(had timing belt done and the throttle body was cleaned). I dont think its the maf sensor as it is only a few months old and doesnt look damaged. I am thinking it might be O2 sensor. Would this cause this? I have checked all connections and hoses but cant see anything out of place. I have reset the ecu and no joy, I have searched the net and didnt come up with much. I planned to try the trick with the paper clip to check for a fault code but there is no et1 slot in the diagnosis box. Any help would be great. Thanks

this happened to me twice in uk, after getting my apexi filter and camcon fitted at around 130MPH, the engine light cam on and the noise of the car changed,

5 mins later it was back to normal, have no idea what it was,

Well it happens on mine at 120kph which is about 75mph and it keeps doing it, not just once or twice. Any way its going in tomorrow for a full check. Thanks for your reply mate.

isnt 120 the limit for the restrictor? - have u had the restrictor removed or bypassed?

my restrictor was removed over a year ago,

Got it back today, finally. Had it diagnosed on Friday from a local place and code P1354 (Variable Valve Timing System) came up. I told him i recently got the timing belt changed and he said it might have slipped a tooth. So my bro stripped it down and it had in fact slipped a tooth. Job done it goes like a dream now.

This happened to mine, infact i got it for a steel for this exact reason.
