Stuttery engine
Discussion
Drove to work today and the engine seemed to be kind of stuttery.. a bit missfire-ish but not a lot. Started and idled OK, warmed up OK. But when I went to give it some, it seemed to accelerate a bit and then lose power for a fraction of a second.
Anyone had this? Anything I should check before I have to book it in?
Cheers

Cheers chaps. Had a look this lunchtime. Seems fine at idle & cold. Went for a drive, when it was hot it got a bit weird, not as bad as earlier tho. Caned it and the car seemed to improve. Dodgy fuel maybe?.. Filled up last night & a bit iffy today. Anyway, I think I'll run it for a few days and see what happens. Perhaps the car was a bit pissed off with not being able to drive fast in the rush hour?!
My car had this on Friday. Started to suddely lose power at any revs then suddely come back again. It was kangarooing as if you were a learner driver. Stopped at the next motorway junction and it died. It would restart but then only ran at about literally 200rpm. Wouldn't rev at all.
Unplugged ECU and reset, checked all fuses and relays, checked HT leads, checked and cleaned fuel pump electrical connections (fuel pump was priming OK though), checked fuel tank pressure (fine) and gave up.
Called RAC. He came and sprayed the entire engine bay and all electrics with industrial WD40. Started car and it ran and revved fine. Went to put the bonnet back down and it died again. Restarted and back to 200rpm. He claimed it was the throttle pot (after a very quick test with a multimeter) so it was low loaded to Peninsula.
Driving it off the low loader, it was fine again and would rev happily.
All I can think was that either something got hot or wet. I suspect wet as I'd washed it the night before, it was pee-ing it down and it did something similar about a month ago during the floods. However it felt to me like petrol starvation.
What I'm most concerned about is that Peninsula won't be able to recreate the problem and hence I'll never be able to trust it again
Any suggestions?

For what its worth, my first Chim developed a really nasty miss-fire when under load & when the engine was really hot.
Went back to the dealer no fewer that 8 times for this problem alone. You name it, it was replaced - all in a very non-methodical approach IMO.
Anyway, it boiled down to the ignition module on the distributer breaking down when really hot (semi conductors have a habit of doing that).
Good thing though it had new leads, plugs , shields, cap, rotor arm, coil, coolant sensor, throttle pot ...
Almost had a new car when I came around to selling it.

New coil less than 12 month ago. Ignition module is a possibility. Is it possible to tell spark failure from fuel failure in terms of symptoms?
Don't dismiss it on being fairly new.Also make sure it is the right coil for the car.
It's a Bosch one fitted by Mark Adams. He reckons they're fairly reliable. My module is on the side of the plenum instead of attached to the coil so it should be slightly cooler but it's still my chief suspect. Will post if/when I get a definitive answer.
