Got a call from my Mum today saying her EA wouldn't start. I went and had a quick look under the bonnet but everything appeared to be connected and normal and when I turned the ignition key, it started and idled fine.
What she said was that recently the car has intermittently lost power while she's driving - just starts to drop off and then comes back on all of a sudden and the car drives normal again.
I'm figuring some sort of electrical fault but that's just a guess. Have any of you EA owners had some similar problem?

Nope.
Full of engine oil, all belts attached, water full, leads connected properly. Nothing appears out of the ordinary.

She doesn't have to say EA for me to know what car she's had for 17 years.

I've been thinking that it could be dirty fuel or lack of fuel. Where is the fuel filter located on the EA?

On my mutipoint it's on the floorpan next to the transmission, basically beneath front passengers feet.
Could also be the fuel pressure regulator or pump.

Yeah, I'd be going along with dirty fuel or even distributor playing?
I did have a similar problem when I first bought mine, and turned out distributor rooted.

Yep, That sounds like a fuel or ignition prob. Did it backfire at all?? I think it may just need a good service (if It hasnt had one allready) Once you service it, Give around the ignition system a spray with some silicone spray (Especially The Dizzy) This just helps disperse any moisture.

No backfiring at all. It just immediately stalls. This problem is still very intermittent, sometimes it won't fault for a week or two then sometimes it's happening all day.
The idle speed controller has been cleaned out thoroughly but it is still doing it. The one time that my Dad said it began to stall on him, he immediately floored it and the car kept going but was stuttering something shocking.
I think most times that it does stall is at low rpm or even at idle while waiting at a traffic intersection. It's happened to me while I drove it and when it stalls I turn the ignition off and then on to hear if the fuel pump is working ( hard to tell even with the windows up because I can't hear the fuel pump from the noise of all the other cars idling next to me ) and then crank it. It starts straight up and idles smoothly. I can't decide if it is an electrical or fuel problem.
Has someone had this problem before with the 3.9 MPI ?

So there is a sensor inside the dizzy?
Does the EA dizzy come with a TFI module?

yea they do, i had changed every part accessable on the outside of the distributor (tfi, rotorcap, rotor button etc etc), before i knew what it was racq guy told me it was pretty common. Got a $60 dizzy from the wrecers and it was good for 2 years until i sold the car

i had the same problem as you. I change everything on my dizzy and made no diffrents, i also thought that i may have had a fuel problem as well, but in the end all it was, was a ECU relay was crook. Start the car and give the relay wiggle (or a tap) and see what happens. Mine used to run well, then rough, and then cut out then wouldn"t start. Give it another wiggle, and then it would start again. changed it no problems since, car going sweet. Good luck :!: Hope this helps 8-) .
