    the quickest way is via diagnostics, but if like me you dont like spending money, then but looking at the faults and symptoms you have. the engien seemed to hesitate, rather than misfire, so have to think fuel, knowing how fairly reliable vw fuel pumps are, didnt want to replce fuel pump straight away, so went for next thing, check voltage supply to the pump to eliminate the relay or car alarm circuits. so found that the pump relay was clicking "in and out", thus loosing power supply to the fuel pump, causing the fuel pressure to drop, causing the hesitation. hope that helps anyone else with

    fault found! turned out to be the fuel pump relay clicking in and out intermittantly. Thanks guys for your suggestions, but glad i didnt go all out for another coil pack and leads first!

    thanks for replies, but i am not convinced its an "ht" thing, someone else has already replaced the plugs and leads, the leads being a genuine V dub set! if it were ht, surely it would misfire moreso at high rpm/speed, this thing is fine at such, its only lower "town speed" it spooks and hesitates.

    If you did remove the cat, the ecu will still adjust the fuel/air mix to maintain correct signal from the lambda sensor. the only way of actually seeing that there is "more" comming out of the exhaust than there should be is by doing a "4 gas" check on a exhaust gas analyser. but you would be surprised how well the system still works without a cat in situ. Of course the only guys who "could" get nervous over the removal of the cat is the vehicle inspectorate on a roadside check, but that is only a rectification notice and a refitting jobbie if ness.

    Hi Guys [n gals]. 94 spec vr6, engien seems to hesitate on low engine revs or throttle. if you gun it, its fine and runs well.but at low speeds it seems to hesitate, almost a misfire or fuel starvation prob. did think it was a fuelling/ starve problem, but have filled the tank and it seemed to run better, but then it came back again does anyone have any clues where i can look, without visiting the dreaded v dub dealer for a costly diagnostic?
