Ok heres the deal, I blew my intake on my 4.6 about 4 weeks ago and the plastic went down in the heads and screwed up my valves and pistons etc., Since then I built a stroked 4.6 to a 5.0 with AFM N42 cams, Patriot Performance stage 3 heads, 24lb injectors MAC straight shot intake, etc. I started up the car today and it ran good at idle it was a little bumpy though, when I pulled out on the street i noticed the car had no power at all, i mean it would hardly move. So I started with the basics spark, fuel and compression tests, I noticed that the whole driver's side bank of cylinders are dead, i can disconnect the injectors and coils and it doesnt make any difference at all. So I know theres 4 dead cylinders on the drivers side, but what could it be? They got compression, fuel and spark? Any help would be greatly appreciated.
