Car Misfiring Ect Under Normal Driving Conditions!

[fEkuaR]

Hey Guys,

This week while driving i was on the highway and the car was running fine i then took an exit and was going doing 60 down a local road and my car started misfiring and carrying on so i went to pull over and the car stalled. I then waited a minute got the car to start and got it home with it misfiring and acting like it wanted to stall the hole time. Once i got it home it sat for around 20 minutes and then i started it and held it at a rev as it was still playing up and it seemed to stop whatever it was doing and drove fine however on and off of most trips ive done this week it has continued to have these mifiring spells and then when i seem to wait around 5 minutes the car runs perfect again!?

Has anyone experienced this i cant figure out whats causing it other then the thought of a faulty wire in my harness.

Regards,

Dan

No ideas guys!?

coil packs heating up and are stuffed probably

i was wondering about that but if that was the case wouldnt it continue to run like shit and not just for a matter of minutes before running fine again?

Could be something clogged in the fuel system? Run a bottle of fuel treatment like injector cleaning stuff, and maybe take the coilpack cover off and see how that goes?

Stalling and idling like that usually means (if everything else is ok) some sort of vacuum leak. Check all your piping, it's possible that one of them is cracked or something, and with heat, it expands.

That would explain it if once the engine was at operating temp it did it nonstop however it is only temperary while driving and then ceases to occur after a matter of minutes

Hey man these people are only trying to give you some ideas to what could be wrong, any mechanic would only suggest the same without actually looking at the car and seeing what its doing and etc etc. to me what they have said sounds like a start and if none of these is the cause then at least you know what its not.

Maybe your fuel pump is stuffed?I had something like what you described took it straight to the mechanics and after pressure testing (fuel system) it needed a new pump.

I had the same problem and still do ATM but car is off the road now. I knew i had a dodgy Fuel Pump cos it was running lean, and then all this started to happen, So i now have a new/bigger fuel pump and also a Z32 AFM being installed this week which should sort the problems out. I have also heard that the pipeing could also be a issue, but i'd start with the fuel pump if i was you!

Ive got a 500hp fuel pump that i havnt installed yet i guess its time to make the change and find out. Although i was talking to a guy at work who got fuel at a caltex same as me just last week aswell and ended up dieing half way down the road. He got towed and they emptied his tank and found that there was 20litres of water in the 50 litres he had purchased. So im wondering if i to got a batch of this shit fuel.
