Hi all,
My Zed is suffering from a misfire/hesitation which appears when the engine is under load and between about 3500 and 4500 revs.
Sitting in neutral, you can rev smoothly and freely without any problems but when accelerating hard, the misfire appears. On several occasions I've been able to "drive through" the hesitation but it's not often that that happens.
Zed is a 1993 TT Auto, Zedworld chipped ECU, decats with Mongoose rear, Apexi air induction, HKS ALC, S2 PTU.
The car is in good condition and passed it's MOT recently with no advisories, as long as I don't give it too much "welly" it drives as normal.
Any pointers on what to look for would be much appreciated.
