Wierd problem...car stumbles/stalls and hesitates...
...especially during left turns.
Car doesn't want to start half the time. When engine turns over it'll try to catch but only does half the time. Idles and runs smooth as long as throttle is under approximately 33% or in a right turn.
Fuel pressure is is good.
repaced ignition control module.
Have an auto tap to determine that:
IAC, TPS, MAF, and IAT all read normal.
knock sensor retards a couple of degrees of timing when enough throttle is given (anything over 33%) to make the car stumble when parked, accelerating straight, or in a left turn (where no throttle is required to make the engine stumble then quit).
While in the stumble the front O2 are reading 0.01xx volts.
Where to go from here?
