Re: Won't Rev Past 5200rpm - 2.5l V6
sir rupert, so your basiccaly at the same point as me, not solved.
Lotuschris - have had a read through your thread. Very interesting and looked very painful too. Did you have any symptoms before it got so bad that it would only just go. You mentioned that at one point it wouldn't rev above 4.5k. Was it good up to 4.5k and then sort of smooth limited? what about even before that.
List as it stands now and will eliminate in the following order:
Blocked fuel filter (will eliminate by teeing in a fuel pressure gauge, if it loses pressure during hesitation then this is blocked, if not the...)
Blocked injectors (will check for leanness using unidiag. If lean and filter ok then these may be blocked)
CAT (will get a resonator in, was put off by exhaust place when i went there a couple weeks ago, they were confident it wasn't the problem)
MAF (I don't want this to be the problem They are too expensive)
Lambda (when last on diagnostics the readings looked normal, although not a lot of attention was given to the hesitation region. I'll basically revisit this when i check injectors above)
