hey all i have a stock n/a vl the problem i have is sometimes when its on idle it idles good then misses 4 a bit then back to normal then when i take off it still misses a little then clears up. when it misses if i rev it it stops straight away. also when i put it in drive or reverse it does it more then. it seams like the more load on idle the more it misses. its quite frustrating. can some one lead me in the right direction thanks in advance chris Some original photos have not been recovered yet.

I would be trying some new spark leads and perhaps check the dizzy for cracks.

Hey champ, I re-newed plugs and leads, dizzy cap and still have the problem. I even did a diagnostics test on the ECU and nothing. I'm thinking of renewing the internal dizzy arm (I think that's what it's called). I'm also interested in solving this so I hope someone can help Some original photos have not been recovered yet.

the car running too rich and the idle being a bit too low will couse that i know that becouse that was the problem in my car when i changed to a larger cam the idle was lower the dizzy was out the ignition timing and one other thing i cant remmember but after fixing those 3 things the problem went away
