right then........the mis-fire was only slight when the car was rolling roaded with the following spec......

1.4 ABD / GT conversion

GT Cam

Poloace chip

Ashley 4-Branch

Stainless Exhaust

Golf AFM

K&N Panel filter

Halfords Dizzy Cap and Rotor arm

Correct Dizzy

Standard Coil

VAG Leads

the mis-fire is really noticeable now since fitting........

268 Schrick cam

chip from Hardhitter

..

i'm sure the recent mod's have'nt caused the problem.........but they have "amplified" the mis-fire

..

at around 30mph in 4th or 5th gear the cars pulling around 2000rpm or less and its really juddery

..

Any idea's ??????

halfords dizzy cap? shame on you! It had a new beru one on there a couple of years back. Anyway, seeing as it's at 2000rpm i'm thinking possibly too advanced. What fuel are you running it on?

I'd go back to basics, fit a known good dizzy; stock GT AFM; check cam timing (as per Schrick) and ignition timing (stock). Make sure you redo the ignition timing after timing up the cam. How healthy is the fuel system? Were the Halfords ignition bits the same as the OEM ones?

Halfords Dizzy Cap and Rotor arm i had that problem till i went to vw and got one
