Was racing a Terminator and starting to pull away on third at around 6,000rpm's my engine started to misfire like a piston engine does when you disconnect a spark plug wire while running. Decided to turn it off immediately. Restarted the engine after stopping but only idle if gas is pressed a little. It dies if not done. Any ideas what can this be? I'm thinking about spark plugs or a Carbon...

You can rule out the engine with a ghetto and/or regular compression test.

will be done on Monday. Just hope everything in the engine is ok....

Joe13BT

Turbo? Vac leak?

Joe13BT

at first, the line that was on the oil fill neck to the oil catch can got booted so I reconnected it. I tough that was the problem so I will check for any other loose line.

Interesting, i now know a few things that can cause it but what is it? I didn't see anything about that in the thread. Did i miss something?

Check for boost leaks
check for spark at both front and rear rotors
check for bad plugs

Mine being a S4 has the mech OMP so no worries for me. I doubt it is in limp mode since i have a stand alone and it being Mech but like I said, will verify none the less..

Joe13BT

Tnks. Any more suggestions are welcome. I solved a manifold leak today. Gosh what a difference in sound it made. Even being a fast car, sounds silently and perfect with the RB mufflers...

its a protective measure programmed in at the factory to prevent under/no lubrication to the apex seals. if the OMP dies it kicks in.

S4's dont even have the limp mode programmed in either. i didnt know it was an S4.

Joe13BT

I hate to say this but... I think you may have blown the seals on one of your rotors! is it sluggish to drive? loss of power?

Glad to hear , thats what im here for!

Joe13BT

It can't drive at all. Could barely drive it to the garage after arrived to my house in the tow truck. How much a seal kit cost? Recommended brand? Hope test on Monday turns out positive...

this all depends on setup and goals for the car. but, if it does turn out to be this you would probably need a rebuild... good luck and i hope the test comes back good too!

Joe13BT

Problem Solved! My Spark plugs were busted. Had a hard time starting it up cause was extremely flooded but is working like a charm. WEEEEEEEEEEEEEEE!!!!!! Some electrical check-up will be done including Comp test anyway.... Tnks Guys...

Don't you love when a problem turns out to be something small and you catch it from the start?

Joe13BT

I DO LOL. Specially in that car. Lot of money have gone to it....
