8v 2.0 Dohc '92 Sierra Engine problem!
I have a 8v 2.0 dohc '92 Sierra engine with a downdraft webber carb, it runs on 4 cylinders until you hard accelerate, then goes onto 3 cylinders and backfires. When you slowly ease off, you can override the problem so why is it doing this? Is it the ht side of it or is it carby side of it?
Would appreciate any feedback.
Cheers
