<div class='quotetop'>QUOTE(RedHeartbeat @ May 7 2007, 07:39 AM) [snapback]92566[/snapback]</div>yeah did the compression everything is fine, and it does purr but it's on the low side of power ( i lose to my friends v6 dakota) Pretty bad...i did the water spray test and spayed water on the exhaust manifold and those two took longer to evaporate telling me no hot gasses not firing, plus i took it to extreme performance here in phoenix specializing in that block style (mostly corvettes with the ls1's and stuff) and the hooked it to there computer and it reads a misfire every rotation on those...and i have all kinds of codes which is normal w/ a cam but some i dont think are like the injector trouble code, idk i still didn't get my tuner but im hopeing that will fix it. i do also know that my low end is gone so to regain that what do you suggest (TC, Gears?) would comp roller rockers help on the low end too because im waiting on my valve cover spacers. What do you think?You can't tell if a gen3 engine is just barely firing by pulling plug wires. The gen3 will purr like a kitten on 4 cylinders. You don't want to know how I know that.What makes you think its not hitting on those two cylinders? Have you done a leakdown or compression test on those holes?
