No, it didn't happen again for months, and then a couple of weeks ago it happened again when I turned on the AC. Ever since then I've been running my AC to see if it repeats. But no clue on what caused it yet.
The same thing happened to me a couple of weeks ago, and also happened a few months ago. I keep the center display in Gauge mode so I can see what's going on. In my case the AFR was jumping up and down, between 14.1 and 15.7. The higher it went, the lower the RPMs. Felt like it was going to stall.
I use 6th when I'm going 80 no problem. However, I don't lug the engine. Op should be able to drive in 6th if desired just don't slam the accelerator pedal unless you're above 3500 RPM.
I would go with a brand new GT and get all the performance options and the warranty to go with it. Plus it would be a brand new car and you can brake it in the way you want to. With a used car, you can never know how the car was treated during the break in period. It might look good but that...
Did you check the spark plugs? I would also say check the injectors but you mentioned you replaced them.

I live in South Fla. I'm 58 years old and no accidents or anything at all on my record. "Safe driver" badge on my license. Still paying through the nose (Geico).
All is well now. Tires are where they are supposed to be.... I triple checked!!! And made sure they got the torque right as well as the pressures. But I'm going to check again anyway.... :thumbsup:
They are supposed to be here first thing today to rectify the situation. I had to remind them that those lug nuts get torqued to 150. Frankly I'm a little nervous of the same guy reinstalling the tires. I'll be watching...
