MAF sensor cleaner?

Might as well put a lsx in it ;-).

If its not the same cylinders you would assume its in the ignition. Could be something in the injector wiring harness maybe.

Like corrosion on the injector harness? Doesn't seem like it would be random though. Could it be something with the pick up coil?

I would suggest finding a way if it's losing fuel or spark randomly. Tfi module?

I've checked, adjusted and rechecked all the electrical connections on engine and injector harnesses and cannon plugs, spark appears to be good too as all spark plugs look perfect.

The problem is so minor and intermittent, most would never even notice it... I can generally notice it because of the slight change in exhaust note. When it does it, of course I'm usually not at home, so I simply turn it off and restart the engine (sometimes without even stopping the car) and I'm good to go for another month.

It's a very minor inconvenience, but it pisses me off that something's wrong and I can't find it.

I have an issue with my car that is solved by turning it off and back on too, it will run like complete ass, like I'm misfiring on 2 or more cylinders. So maybe we have something in common, I've been trying to find my solution aswell. It will also cut out and feels like it dies randomly at high rpm shifts. I have a wideband and when it does the misfiring / running rough I recall it being pig rich, but it's been a while since it's happened.

Here's a video of it happening on the 1-2 shift, not hitting fuel cut as I've tried to see if it's because of shifting at 6300 but I've taken it to 6800 without any problems.

One other thing I've noticed.. mine seems to not have the problem as often provided I start the engine without touching the gas pedal (zero throttle)... not sure why it makes a difference, but it does..

Have you done a sweep on the tps with a volt meter ?

[mardyn]

Yeah... that was one of the first things I looked at when this started happening.
