Won't Rev Past 5200rpm - 2.5l V6
FIXED NOW 17/11/08- see later post
I need some info on what this could be.
1)My car accelerates ok but as soon as 5200rpm is hit the car sudddenly stops accelerating (like a smooth limit, kind of pulsates)
Occasionally breaks through but only slowly or not at all. (edit: Now gets through but hesistates)
2)Cars been running cold 50-65°. removed tstat yesterday, found it sat 1mm off seat so i removed some of the expanding wax stuff so that the rod slid further up. Checked it in a pot and now closes fully. Reinstalled in car, now runs at 70° (edit; Now new one fitted, runs 73gauge=85 ecu, to 90 gauge 95ecu)
3)Annoying Cold starts where depsite applied throttle, won't accelerate, engine pops if additional throttle. Goes away after 20 seconds (edit: still happens, worse on hot days as summer is upon us here in nz)
4)Full throttle is weaker than say 80-90 % throttle
Serviced 2 months ago oil, oil and air filter, plug check, cleaned maf. Fine before service, felt it was lacking balls after service but may have been placebo.
edit: new thermostat fitted)
Things I've tried:
have tried driving hard with MAF disconnected, although rougher elsewhere, this didn't change the high rpm symptoms. New thermostat and correct running so this not an issue.
I wanna know what you guys think.........
