The car
(rev2 turbo) is well maintained, will good fairly recent plugs, ht leads, cap n arm, walbro fuel pump etc. Running good afr's and runs well.The coil was a couple years old and died on me a week friday.
No running problems prior to this. I replaced the coil and ignitor and now it loses throttle. Tried another coil and ignitor and no difference. Even added earths to them and still the same. What I mean by loss of throttle is, I can be on light throttle,
wot or cruising and it just starts engine braking, which is vicious if you're boosting and can snap back on power making the car unstable. If you press the clutch the engine idles perfectly but no matter what throttle input with the pedal the engine remains at idle, If the engine is still engaged with the drivetrain and give it throttle the turbo still boosts and the bov still blows off (recirculated ssqv) but no power.When it first started doing it, it would stay
with no power until you let off the throttle and reapplied it, but it seems to be getting worse and this no longer works to bring it back to drivable. I can drive it and it never faults, other times its every time I apply throttle, lightly still in vac or boosting. It used to cut on partial throttle (spooling)every time at 4k revs for some reason, that was the only reoccuring thing I found to recreate it.Turned ebc off so running 0.8bar but boost or vac it still faults.
Removed the ecu and looks perfect inside, with the tps disconnected it still revs up so I don't think it's related.
I'm just a bit baffled.
It just cuts in and out like a switch no missing or pops n bangs, cuts exactly like overboost,
fuel cut.Anyone experienced anything like this?
Any help appreciated
