Sorry for the long delay, was out of town and only had access to a dialup connection... Anyway, I don't think it's the throttle cable since it'll redline in neutral and park when you floor it. As for the fuel pressure, I wasn't the one checking it, so I don't know but I'll find out. I don't believe that anyone changed the injector sizes, but that could be a possibility. It was running rich at one point before I changed the AFM. The car is initially from the Los Angeles area, and now the car is definitely at a higher elevation here in Saskatoon, but you'd think that the other car that I have would run the same as this one if that were the case unless there's some elevation tuning differences that I don't know about. Apparently the mechanic had no clue about the speed sensor problem until I told him about it today... so basically he's going to see what all it controls and if it's causing the ECU to go in to 'limp mode.' It's a long shot, but I'll try some of the stuff mentioned here as well as the speed sensor issue and see what happens.
