I have the 93 octane flash, with the switch back to stock included. For the first couple of weeks it worked fine. The car hasn't been driven for about 2 months and now when driven it will go into limp mode when i stop at a stop sign or a red light. It also jerks sometimes when putting it in drive.

I took it to the place i got it flashed at and they reflashed and tested it after clearin the codes (that were all transmission related). It was fine on the way home and to work this morning, but on the way home it started again.

Any suggestions?

 

*update*

The place that flashed my vehicle, put it back to stock and wanted me to drive it about to see if the problems still occur, and yes they do, worse than ever. I guess the transmission is done, i have put under 1000 miles on it since i bought it, and it only has 29300 miles on it.

It wont register what gear it is in, will go into limp mode and be slow as hell and jerks when changing gear or being put into drive.

Any suggestions to the problem? It sat for about 2 months and wasn't driven.
