thanks leaky but no good, swapped with a known good one from wreckers no difference and not getting your code.
i am getting errors P1131 (kinchrome code reader) and P0171 (torque pro).
have checked for vacuum leaks with the brake cleaner spray trick but nothing detected.
have changed coils, plugs, oil and coolant since purchase and this issue seems to be getting worse, cars runs fine for a bit then starts to run rough and not rev properly.
not sure what other home remedies i can do, may have to take into a local mechanic but wont be until next week.
