We already know that. But going from a 28 injector to a 30lb 3 bar probably around 36lb at 4 bar (4 bar is base FP) will cause major problems if they haven't been scaled with programming softwareOriginally posted by 1bad83ta View Post-08 G8 GT DD: Rotofab CAI, HID's, Breyton Race GTS'

All I can honestly tell you, is those injectors have been in the car since I bought it.. Same tune.. The car ran fine, always a little rich, which makes more sense now that I know they are the equivalent of 36# injectors.. But it ran.. I pulled the intake and found fuel around every port on the intake and on the heads, thinking that can't be helping it run right..

I would start there, your car ran for 2 minutes, its still in cold startup. So your pcm is dumping fuel to get the car up to temp. Its running rich with 28 lb injectors. The pcm doesn't know it has 36 lbers and its dumping even more fuel. Your O2s don't start switching until it goes into closed loop. Basically the pcm has no idea its flooding your engine until its in closed loop. Even more so, your injectors were flow matched and they probably flow better than they used to!
Also take into account that maybe they were scaled with a tune. Its possible the previous did not know they were 36 lb at 4 bar.Last edited by shawnc16; February 27th, 2011, 12:44 PM.-08 G8 GT DD: Rotofab CAI, HID's, Breyton Race GTS'

like i said. alot of tuners are hacks. probably didnt get tuned well in speed density. when the maf failed the car gets pushed into SD and killed the plugs.
you replaced the maf but the plugs are dead. try the good maf and new plugs once the intake is back on and torqued
then visit dr phil to fix the tune from SD up.Comment

getting new plugs tomorrow..sigpic
