When I bough the car, the car would hesitate and cough when throttle floored. On investigation one of the plugs was knackered and the car was dropping a cylinder when under load. Suggestions were that the car had been run on cheap fuel by the previous owner and not mapped for UK. Since owning, I've had the car mapped, plugs changed and only use V-Power. I've only done 800 miles!!

One morning last week this happened again. It reminded me of my rover turbo when a manual boost contoller was added and the ECU cut in for safety. It has not happened since. Any Ideas? Could it be:

I was only about 4 miles from my house, maybe the car wasn't warmed up enough? ECU safety feature?
I'd been arsing around with my Apexi controller, maybe left it on the 0.6 bar setting? Wouldn't make the car jerk would it??
My plugs knackered again?
Any other suggestions

Got a VTA dumpvalve, has it?

No ideas?
Think I'll have a look at my plugs tomorrow!! Just such a hassle to get to them!!

VTA dumpvalve?? I haven't changed my turbo setup at all. Its a 98 TypeR

i would check the fuelling m8. starting from the fuel pump.

try a set of iridium plugs in it with heat range 7. i had the same probs with mine running standard plugs but when i installed the iridium ones my car was transformed it stopped hesitating and stuttering it now goes like a rocket i am running 17.2psi boost and am suprised at how well they perform, you might want to give them a go.

Cheers, I think I'll change my plugs, thats one less thing it can be. On the fuel front, just had a Walbro fitted by a mate but the car stinks of petrol all the time now so I need to investigate this!! Apparently the rubber seal may be knackered on the panel to the tank so I'll have to have a look.
