Jb4 misfire

1ndonlySG · 08-06-2014, 05:12 PM

Hey guys, so I'm having a very annoying problem with my car. I have a fbo set up pushing about 16-17 psi but my car doesn't move! Everytime I go for a quick pull, my rpm just rises up like crazy and misfires. Some people are saying check your spark plugs and decrease the gap, and some are saying my clutch, my car only has 5k miles on it. Did anyone else ever experience this? Thank you

Take the JB4 off and see if the car still does it. If it does then the problem is narrowed, if not then you know it's something else. Pull a plug and check the gap.

Do you mean the car physically doesnt move when you press the gas? or is just slow?
Sounds like you have a slipping clutch or transmission if you just rev and dont move...
Maybe im a few beers deep tonight and just dont understand you.

My car is just too slow for a fbo, I think my clutch is slipping, what can I do about it?

Buy a 335is clutch kit and install. There's a good DIY guide on here

When was the last time you changed your plugs?
Any code?
