Waxoyl and Misfire ??

[Torquemada]

Spent the weekend scraping, hammeriting and waxoyling the front wishbones. Pleased as punch with my achievements, start the beast up this afternoon and it's running like a bag of bones. Idles okay, but try pulling away and I am lucky if I can declutch before it stalls. Prod the throttle at idle and hesitation and misfire ensues, though okay at constant revs. No improvenent when the engine has warmed up. When I get going it's fine until I attempt to accelerate. Could I have disturbed something in the vicinity whilst merrily chipping away at the wishbones?
Further clues:- replaced the coil while the hammerite was drying (due to oil leakage). My first thought was that I had fitted he incorrect coil, but same problem happens when I put back the original coil. Replaced the HT leads last week, but the car was running fine up until today. I have tried cleaning the stepper and disconnected the ECU, but no improvement. That's about the limit of my knowledge. Frustrated! Any advice gratefully received! I've broken my golden rule - if it's running OK don't touch it!

Its stating the obvious, but are the leads in the right order?
Sorry but its usually the simple things that catch me out!
Good Luck

Check the main lead to the coil. I had a problem on my Peugeot where it was stuttering and generally misbehaving which was traced to a poor connection to the coil.

I dont know what engine your talking about, but that problem could be advance/retard related?

ie, either a vacuum tube to the dizzy or a wire loose to a box of tricks ???

I'd look for the obvious also. Had similar problems last week, turned out a sparkplug lead had detatched itself - which isn't obvious unless you check each one seperately by lightly pulling then reseating it.

Check the coil as a good earth,had a similar problem on a friends Griff when he had the coil mount powder coated,we had to file the coating off to get a good earth.

Budd - maybe I'm being thick, but surely earthing the coil casing is irrelevant? The coil internals must be insulated from the casing as the high voltage being induced is effectively being earthed through the spark plugs to create the spark?

Thanks for the advice. Problem solved yesterday - turned out to be the ignition amplifier module (adjacent to the coil).
Still suffering from post traumatic stress after having to do the long weekend in Yorkshire in a diesel Rover.
