I would try and see if it is different pressure on hot and cold starts. Somewhere around 70-75 psi is where Alvin says that the Injectors will have trouble opening so that may be the problem.

Is that 70psi on both hot and cold engines?

Best to be asked for the particular vehicle in the specific forum section. They all have different OEM strategies and different things available.

Does this not sound like a bad switch at the transmission shifter or on the trans itself?

I have to admit I would follow the instructions and contact support.

Read is a full read on GM as long as the module is selected. Write can be calibration only or entire. At least on the older stuff. If it was me, I would hook it and see if it has any options for...

That's the editor so those should be all the DTC's available, not the ones that are set. Or am I missing something?

What are the screen shots supposed to do?

We can't really answer whether you have a current file or not without reading the TCM. Only you can prevent forest ..., I mean only you know that.

edcmat-l1 can remotely tune it better than most in person tuners.

Running means running the test or checking for a problem. It doesn't mean that the DTC is being set. The next line is what it has to see to set it.

Gen 3 can only handle so many channels at one time.

It would be a lot easier on you and everyone trying to help to just stay with one thread, at least until something drastic changes. Keeps you from having to explain everything multiple times and...

You are half way to the instructions given in the other post you made. Now the log half.

They are universal, even credits are now universal. It sounds like he is talking about the credits he used which doesn't matter since they are locked to his vin number if he used them.

My bet is he doesn't have HPT.

I’m pointing out the closed loop with trims Tuning suggestion not the maf.

- then turn the MAF on and tune the MAF (afr err)
- re-enable closed loop



Need to put it back in closed loop and use your fuel trims to dial it in.

A current version of your tune and a log of the problem is pretty much required every time. But making a new thread for every problem isn't. It would save you time explaining things to just add to...

If I had paid any attention to what forum you had posted in, I would have also told you that you would get more help if you posted in the correct forum. I'm not sure why people think that this is...

Log and tune needs to be added to have a chance for any help.

Screen shot shows as "permanent" (only).

Since that is a permanent code, it may have to see some drive cycles to clear? At least enough that it has a chance to rerun the test.

Why?

As always, tune and log needs to be posted.
