I mentioned that already, thats my guess to.

I left 3 messages today with no return call. Really fed up but willing to hear them out.

How long they gunna have thing?

Are they gonna pay your car note this month?

Dang, they buying it back from you?

Its doesnt mean there is something wrong with the TC, you just have to adjust the tune for most aftermarket TC's. I had a circle D in my LS2 camaro and had to adjust the miss-fore for it, its pretty common to have to do that.

Believe me guys, I would not have taken it to them without trying everything short of pulling the lid off the motor.

I can, but it doesn't change the fact that as the truck sits now, with myself trying to not have to work on a warrantied motor is fine.

If they call me and say "I told u so", I'll apologize and eat my words. But plugs and wires labor ALL DAYl with no call tells me I was right.

So, I will await their call and continue to believe that I and all u guys were right. It's not ignition/fuel related. And I'm sure that contrary to what he says, my Aeroforce scan gauge is not "inaccurate" when misfires got from 0 on all cylinders to 160 on #8 and none on others.

I'm just upset with being treated like Joe blow off the street with more money than knowledge. I offered everything that I had done to remedy situation. Totally discount my information? Come on....

I think your missing what Lorenz is saying.

If the converter is still installed and the tune was not adjusted, the that could be the issue. A stock tune would yield the same result. Now if you have taken it out (converter), then that's a different story.

Unfortunately you are "Joe Blow" off the street to them. They don't care how much you may or may not know about cars. They will tell you the same thing they'd tell my wife. The only thing they care about is getting in your pocket. That's the unfortunate truth about this whole dilemma.

what he said, it doesnt matter if both computer's/tunes are doing it if it hasnt been adjusted in the tune

Atleast Matt and Zac get it, lol.

It WAS adjusted in the tune, and didn't affect it either way.

As far as Joe Blow, I have a personal relationship with this service manager. I have had for 5+ years. He knows better. But I know that he has to go on what the tech says.

Now, guess what time he called me yesterday? FRIGGIN 10:30 PM last night. WTF?

Says they pulled the valve cover (durrrrrr) and couldn't "see" anything out of place or damaged. I don't know what the process is now, I expect a phone call this morning as I was sleeping at 10:30 and told him to call me when I could better comprehend what he was saying.

You said you had a mail order tune right? So that means that you don't know what's been adjusted in the tune without seeing it and comparing it to a stock file.

You're really worried about it being a broken valve spring. I highly doubt that it is. If it takes the load all the way up to 4k rpm and then decides to mess up CONSISTENTLY there, then so be it. But I don't see a mechanical issue being consistent. I definitely think that it's tune related from the converter install.

Broken....not so much, but a weak valve spring causing valve float at high RPM's is not that uncommon.

But would TC problem cause misfires on only ONE cylinder?

Talked to Alvin and had him look my tune over. Definately the TC was accounted for in the tune.

Still haven't heard anything from them.

Did you tell Alvin about your issue or did you just ask if he "tuned" for the TC?

I told him what was up, and what had been done, and the first thing he said was pushrod........

So I just got a call.....bout damn time.....anyway, service manager was driving my truck, and says:
"Well, I'm drivin it, and it runs awesome, until you put your foot in it real hard, then it starts breakin up."

Well, Chris, that's the whole reason I brought it to you.

"Well we ohmed your plug wires, and two were over 150 ohms, really high."

Well, I thought you were gonna put stock wires on it and see?

"well we did and it still does the same thing."

Well, did you pull the valve cover, I was sleeping when I talked to you last night.

"Yeah, pulled the valve cover, and everything looks fine in there."

What about the pushrods?

"Yeah, well if it's a pushrod, that's gonna be a whole other deal."

Well, did you check? What's next?

"Well, your fan won't turn on, and we can't activate it, so I'm thinking the ECM is bad. We ordered one, it should be here tomorrow. That may be what's causing all this mess too."

Okay, keep me informed.

Did you do a crank re-learn with a tech II tuning software with the tuned pcm installed? If you didnt have a crank re-learn done with the tuned pcm installed you can't rule out the tune.

I don't think the dealer will find a problem, it will continue to missfire with a stock pcm if the torque converter is causing the problems. The easiest way to get this resolved would be to call JP and pay him to look at the tune and data log it. EFI Live scan tool is very good and I prefer it over a Tech II anyday. It's alot easier to use and find problems with IMO.
