hi newbie here just wondering if anyone could help or have any idea's.
I have recently got a mk6 1998 escort si 1.8 16v basically since ive had it all it seems to do is stutter pullback sound like its hitting rev limiter between 3/4k ive tryed everything new sensors including maf still no joy, i have also changed fuel filter which when i take it off to check it and then put it back on the car runs ok for a while then the problem come back again!! Im getting really fustrated as i cannot pinpoint whats causing it, im now thinking maybe it could be fuel pump but surely it would just pack up rather than playing up before it dies.Also i have noticed a valve on the injection rail which when i press it fuel just trickles out when car is running or not. dont know if its meant to do that, so if anyone has any idea's please let me know.
cheers
