3800 Code 0300 Random Misfire

[Bliss Racing]

What would cause that?? Bad Exhaust Leak??

I have all new gaskets all over the motor....and redid the whole vaccuum set up. I also have BRAND NEW Fuel injectors and Spark Plugs!!!

The Cross over has a bad leak before the front O2 Sensor.......would that cause a random misfire??


The car runs just fine.....

What about a stage 1x blower cam??

"The Stage 1X, Stage 2, Stage 3, and Stage 4 Cams will set a P0300 random misfire S.E.S. light, therefore this code should be removed from the PCM with an INTENSE Powertrain Control Module or other custom PCM programming."

Once again you answer another question of mine!!! Sorry i haven't called lately....i've been so busy with this new job, and my computer is infected, so AIM won't work...i have to reload everything when i have a chance. I'll hit you up sometime soon!!!

Thanks again........It's wiered though...i haven't thrown that code in like 3 weeks....then all of a sudden i got the Lean code.....probably the exhaust leak causing it.......and now the MISFIRE code......that came on yesterday!!

should i expect that code then?

I got the stage 2 but i have a dhp

SYP: You will get that code, unless you have a custom DHP, with that code removed specifically..

Stock DHP will throw that code.. just have charles remove it.. or find someone with a programmer.
