missfire

[edmy]

for weeks now im suffering a miss fire when my car gets upto temp, only when im at full temp it decides to miss at 5000rpm or above and only if i floor it not when i ease it in!!

ive changed plugs twice, coil packs once and ignition amp!! how much more money am i going to have to put in to this b4 i cure the problem!

would appreciate any help as the car is going to be sold if i cant sure it as i cant afford to run the bugger.

is it cold - what boost you running? I find the stock ECU to do funny things at anything over about 8psi!

Maybe just it is sensing too much airflow and going into rich and retard mode.
