Well mate..
Sometimes it's just too tedious to read through pages of waffle to maybe pick up the odd relevant sentence.
And from experience fixing a lot of young guy's cars (not all, but many.. and to be fair, it's not always young guys) they are looking for one magic bullet to fix their car when in fact all the mundane basics have been neglected.

Where are all you guys with the CFI EA Falcons?
Is it just my car or is yours just as slow?

Re: Power issues with the EA Falcon... please help me!

Hey guys, well I havent given up hope yet. Took my car back to the mechanic this arvo and told him that my car drives like poo so he took it for a test drive and told me that there's a good chance the engine timing could be out or something along those lines and there could also be a good chance that the catalytic converter is partially blocked.
So I got the car booked in again for monday.
Hopefully this will be the answer to my troubles.

As for switching from a VS to an EA CFI... the power difference shouldn't be that spectacular should it?
I mean we are looking at going from around 142kW to 120kW right?
The weight difference wouldn't be the big either.

completely different tho, a vsII is faster than my ea MPFI (and as far as I can tell this is normal?)

Re: Power issues with the EA Falcon... please help me!

I own a CFI EA and my gf also had a vsII so i've driven both plenty of times...

The outright power difference isn't huge (i think the cfi has better torque or close anyways), but in terms of acceleration the commo's 1st gear ratio helps considerably. And so makes the car seem much faster and more powerful than they are.. Especially compared to the ratios of the falcon.

But I am 100% sure that it doesn't take almost 10secs to reach 60km/h in mine. And I also think I had a blocked cat and its sucking some power.

Re: Power issues with the EA Falcon... please help me!

Yep gotta agree, in my opinon, i rekon the engine aint breathin properly.
Stick ya head under the car and listen for any hissing that could be coming from the exhaust other than the end its supposed to.
If gettin the cat and muff checked for blockages comes up negative then the power issue has got me stumped after all the other things you have gotten fixed/checked.
Before i got my EB II 5 spd, the old man's car was an EA fairmont CPI 3 spd, and to tell ya the truth it wasn't that gutless even when on gas.(Had no probs spinnin its single spinna) But the sad truth is that MPI is the way, thats why cpi was phased out.
P.S. The Ea did have the temp fluctuating problem 2. Even after it was flushed by the mechanic.....Problem = air bubbles cruisin through the system, Solution = needed to be purged/expelled by a simple process explained in the gregories manual.
GET THE GREGORIES MANUAL....its the ford owners holy bible.
Cheers,

Weapon of choice.

roll 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.
Cheers.

How's your vacuum and fuel pressure. Also sounds like a plugging cat could be the culprit as well, but less likely.

Ever notice that there's so many high performance parts available for GM products?

Did you ever think that maybe they NEED them?
