Question About My Engine

when i start my car and give it a bit of a rev when it gets to around 2500 - 3000rpm it sounds like its missing.
but when it warms up there is no such problem so what i am thinking is this a part of the management or is there something wrong with my car?

could be a lot of things, i had it on mine not long back and discovered it was a cracked exhaust manifold, when the engine heats up the metal manifold expands and closes the crack up

Mine misfires from cold. Oddly enough, it doesn't do it all of the time.
I just thought it was sticky valves or something?

could be that too, or a stuck tappet, might be worth getting some forte fuel/gas treatment off ebay and sticking it in the tank and take it for a long blast up the motorway

Dads cougar was doing the same thing and if i recall corectly it was the distributor cap the arm inside was bent (somehow) and it missed on the odd occasion.

Could be a multitude of sins, CTS could be dicky along with all the above, going to be a case of trail and error, so start with the cheap stuff first

Does your car have a diagnostics socket?
If so find someone with one or buy one of the cheap diag modules from ebay.... there not bad on rovers!
