Need help...

[ejsa6]

Stage 3 and just recently started getting a p0300 code only, nothing specific. I've got the ICM deletes, brand new 2.0t coil packs, tried a second set of spark plugs gapped at .26,new o2 sensors, new coolant temperature sensor, triple checked all my vacuum lines and seems well from what I can see. Boost gauge isn't showing any leaks and holding boost. I've done a compression test all cylinders are between 165 and 170. New maf sensor, injectors only have 3000 miles with a new fuel pump. The only thing I haven't done is hook up a vag Com since I do not have one

So any advice would be greatly appreciated.

How far are you from Houston?

The one thing you dont have is the one thing you need

You need to log misfires so you can see what cyl it is, and then do the misfire hokey pokey based on that.

I'm in abilene so somewhere around 6 hours or more I believe

That's a hell of a drive. If you were closer I could have scanned the car for you. If you happen to make it this way let me know.

Funny thing: when I converted it removed my ability to see misfires via vagcom. Weird, huh?

What exactly did you do?

What exactly did you do?

Rs6 coils, harnesses, and icm delete. Supposed to be plug and play but having issues with codes.

I believe misfire rec is based on the crank sensor so coils should not have affected it.

I think maf scaling bringing load below the activation threshold is the reason it gets disabled most of the time.
Some tuners may also do this on purpose to cover for poorly idling injectors.

Aah I see. I only assumed because I no longer have misfires but have rough idle. Sure it's the damn injectors

The measuring blks for misfire will say enabled or disabled in the 4th box.

What injectors?

There are some tuners who turn off misfire logging, which if I recall correctly, is easier since the knock sensing can be triggered by very subtle/minor misfires. I have the same issue, jballou and I were trying to log misfires and my jfonz tune wouldn't allow us to log them.
