Well I have been with the head mechanic at the dealer this morning versus the other regular mechanic and we have come to a preliminary conclusion after running the consult while driving & duplicating the problem as the car is not showing any codes. The initial thoughts are torque converter failing. We duplicated the problem several times...while cruising while he took the consult and kept running different tests....like a readout every other second of every parameter and what finally came back is it looks like the TC is screwing things up as something about it being at 94% when rpms drop by 200 (actually 50-100 rpm as per the consult) around 4000rpms while under hard acceleration. We also noticed during the test drives that there is a very slight pinging sound and they are going to look into the timing and knocksensors to see how it is related. I had heard the pinging sound before...but ever so slight and only during a specific situation....we got one test run in and it initially looked like somehow after a WOT run and then cruising @ 70mph that when you give it a little gas again....slightly that the timing is not correct. We went through all the checks....high octane, regular service (fuel filters, etc.) and then he says....might be an injector is dirty.....Hmmm now I start laughing and he realizes that he had told me about a week ago that I did not need a fuel rail flush and refused to do one. I just smiled and said whatever it is...again check it all over and I want it perfect....he is still a little hesitant on the exact cause of the pinging as it only occurs under a very specific set of circumstances...but will look into it. In the end he gave me thumbs up and said that he has not seen a Q maintained this good in a very long time...
Well the TC thing will be resolved late next week as I am getting a new transmission & TC anyway...talk about timing. Well it looks like my trip to T3 will be on hold for a little while as it does not initially appear to be knocksensors.
BTW...the head mechanic is very familar and a fan of the original Q and told me stories of chasing down 5.0's when he had his Q which made things easier and he said that he would make sure that he over sees any work done on my car....Now this is service what I like in service....A guy who really cares about cars, even though I am still upset about the rail flush issue we had a couple of weeks ago. I think I finally earned his respect and he was telling me of a guy here in Miami that use to own a Q all modified that had a different cam in it that was all NA doing the 1/4 in mid 13's. He had not seen the guy around in about a year...so don't know if the guy is still around, but I will try to find out who he is.
Also they are installing my 4.08 rearend
.....at least that will be done. I should get the car back tomorrow....I don't want another weekend stuck in a G35.
