I have a 94 hatch with a ls/vtec with b16 pistons, dc headers, itr intake manifold, xs power cams, springs, retainers. teh car automaticly retards the timing about 6 degrees. I triple checked the timing belt and marks, and they are on the dot. I originally had a ls distributor and I swapped in a gsr distributor, it ran cherry for about 30 seconds and then back to square one. I swapped ecu's and still the same. It idles like **** and I need some help. I'm guessing its the cams, but how would it retard the timing? Help Please thanks.
