A little problem...

runthis · 11-19-2010, 11:27 PM

So I was driving along on the freeway the other night (on a date). I'm in 6th gear cruising about 70, I went to step on the peddle to pass someone... Nothing. I let off, and try again, this time took the pedal all the way to the floor the car start jerking and shaking violently. I get off pull off the freeway. and stop at a gas station, and as soon as I get out I can hear my auxiliary fan on blast. I turn the car off then back on the fan went off so I continue on.

The next day I take my car for service and they said it's a miss fire code, and the replaced all of my coils, and spark plugs. I get the car back its doing the same thing hey replaced the temperature sensor... they delivered my car to me today, I took it out tonight and its doing the same thing I data Logged it but don't know the best way to display it on here...

Anyone have any clue what could be going wrong?

They see misfire codes but it could be from a variety of things... Plugs, Coils and temp sensor replaced... Perhaps something fueling related? Maybe cam problems?

Long cranks? SES light??

Sounds like a coil issue to me.

My top guesses - HPFP, Fuel injectors

Yep, sounds like it.

Maybe two weeks before, they replaced my HPFP, injectors, pressure sensor, and Vanos solenoids, and removed and inspected camshafts to ensure hookrings were not damaged.

Maybe thay just didnt? If the car worked fine for them... Also the nw HPFP might have been a lemon as well

I hope all the best dude.

I had that happen once, I reset all adaptations and reinstalled tune firmware and software and the problem was gone.

Otherwise its hardware related ... Pump Injectors Coils Plugs ETC
