Hopefully this post might belong in the Electrical section, but you guys seem to know a bunch more than I, so I'll let you decide...

After fitting a new fuel filter this afternoon in an attempt to cure my own 'hesitation' problem (unsuccessful, but the filter was shite anyways), I was heading back from the gas station and accelerating fairly enthusiastically in second when, at between five and six thousand rpm, ALL the warning lights on the dash came on and stayed on. The engine sounded fine, so I went home (at a reduced pace ).

When I parked, I let her idle for a minute, but it was REALLY high, like 1,600rpm high. Then the lights went out and the revs gradually sank...to less than 500rpm! I switched off, waited, restarted, and the revs were still a bit low but not as bad. (Checking under the bonnet revealed the filter and hoses to be sound, so hopefully that's irrelevant.)

Can anybody diagnose me? Should I be worried?

first thing is to see if your fuel filter change drastically improved your fueling situation and is messing up the ecu. Unplug the battery for an hour and plug it back in, turn the car on, let it warm up, turn it off, turn it back on, and drive away.

many thanks, I'll let you know...

Maybe you should have your alternator checked out. I think it's just a coincidence that this happened when you replaced your fuel filter.

scottzg - if there weren't several thousand miles of cold inhospitable ocean between us, I'd be buying you a good few beers right now.

Reset the ecu this arvo, and she's running smoooooth! So, had the ecu 'learned' to adjust the injector flow to suit the old, clogged filter?

"...Maybe you should have your alternator checked out."

vrg3 - yeah, I think I will need a new alternator, cos the lights dim at idle, and the a/c display dims when i turn the driving lights on, but at least it's not messing with the power delivery (noticeably, anyhoo).

Cheers guys.

Wow, your old filter must have really been in bad shape if resetting the ECU solved the problem! Glad you got it fixed, though. Good call, Scott.

Mmmmm beeeer.

Glad it was that easy
