Re: Power issues with the EA Falcon... please help me!
Yes. I have an EA 3.9 CPI (dual fuel - Impco LPG system).
Until recently, it ran just fine, but suddenly became gutless. The engine revs freely and smoothly in P position, but once "drive" is selected, there is little pulling power. If handbrake is applied, the car won't move an inch, and engine stalls whilst increasing revs. This is the case when running on petrol or gas.
Distributor and module were recently replaced by a mechanic. (some time before problem arose). I replaced MAP sensor, to no avail. Ignition timing is fine. Throttle cable is fine. Plugs are fine. New air filter. All hoses fine.
My guess is that the 3 speed trans has gone south. (either bands or torque converter).
It's wierd. Apart form the severe lack of power (which happened without warning), everything else checks out ok. Car runs smoothly, and doesn't stall under normal takeoff, albeit a SLOW takeoff! (Steep hill takeoffs are almost impossible!) However the trans doesn't slip at all, the engine just labours)
I've heard that the 3 speed trans is bullet proof.
I will take it to a trans specialist to get the bands adjusted and see what happens.
Like the original poster of this thread, I am at a loss.
