Northen Rolla Posted June 5, 2005 Report Posted June 5, 2005 (edited) Lend me your collective thoughts on what could be the problem, :) My Check engine light keeps coming on, sometimes it comes when you give it a stab, it'll cut power for a split second then the light comes on and most times it goes off again. Other times just driving up the highway the light will just come on and won't go off till you shut the car down. Timing belt was done at 109,000k's (now up around 140,00k's) Oil is fine Engine temp runs around 80*c average (splitfire gauge). Could this be poor tuning?? or a faulty sensor somewhere?? The boost has been increased from standard to 11 psi, standard turbo will take 14 and the cut out (that's when the ECU says stuff you and lock's you back to 5psi) is about 13.5 psi and i'm getting nowhere near these levels. Any idea's???? Edited June 5, 2005 by Northen Rolla Quote
Northen Rolla Posted June 5, 2005 Author Report Posted June 5, 2005 And that would be mounted where?? down near the cat converter?? Quote
Northen Rolla Posted June 5, 2005 Author Report Posted June 5, 2005 Yeah it was located after the stock cat converter which was directley off the dump pipe, but when i had a custom dump made the new cat got put down below the fire wall, thus relocating the sensor. i'll check it out. Cheers Quote
