Just recently began driving an EA 5 spd..... and here's a problem which SOUNDS like a fuel delivery problem, but me not being an injected engine specialist (always had carbied cars) I could be way off.

Sometimes, it will accelerate normally, not bad! Occassionally I get this sluggish feel, a bumpy "pull-pull" type as if it isn't getting enough fuel or is getting it uneven. Kind of stunts the acceleration etc.... is this an injection problem and is it common (and hence, easy to fix)?

Your thoughts are appreciated! H

Well its either a fuel delivery problem or an ignition fault. Try a fuel pressure test, if thats ok then id check yer ignition - dizzy cap, rotor, leads, etc...

I'll do the feul pressure test.... let me explain a little more - most of the time it pulls fine, sometimes it starts pulling then gets all sluggish in spurts, kinda rough, most often when I level out the revs.

thanks for the advice, I'll do pressure test, but has anyone had similar probs? H

I have an EB and when i first got it it was only running on petrol (mine is pet/lpg). And even on petrol was running rough. Got the injectors fixed for $150 and ever since then she has been running beautifully

HEA,
My EA all of the sudden got this weird hesitation under load, it was getting worse and worse... turned out to be the ignition system (leads + cap). So check those if you can't find it...

Like you I also have this prob and found that if I floor it then the prob goes away.?? why I am unsure as like you I have also only had carbies.

I drive a 3.9 with 5 speed.

So far I have replaced the fuel pump, fuel filter, had the injectors checked and cleaned, replaced the dissy cap, leads and plugs.

It is dual fuel, and when on gas no probs, this would automatically eliminate electrics.

The only thing really left is to do a pressure test on the fuel line, but like most things it will have to wait until the cash is there.

Hope this will help eliminate some of the uncertanties for you.

Joe... :-))

hate to state the obvious, but have you checked the fuel filter?

Had the same problem. Turned out to be the ignition leads.

That's some good info to get me going.... fuel filter is near new.

And yeah, under load it sometimes hesitates (3.9 5 spd also). also, when I back off it tends to shudder at times and gets very rough.... so sounds similar to some other probs here.... I'll start with some of the checks, fixes etc mentioned here, and pay for what I can't do I guess.

Anyone recommend any injector places or will standard mechanics have enough of a clue? (score one point carbies, just get in there and pry around, wish it were so easy!)

Thanks heaps, and any more ideas, DO post em! HEA

It could also be the throttle position sensor.
It gave my MPI similar problems.
