My crossfire entered limp mode after driving down a main rd and the rear tires locking up. I spun and almost crashed, luckily I corrected the tires, and pulled off the side of the rd. I was stuck in 1st gear but was able to make it home. The code I got was the speed sensor and secondary air intake? I replace the conductor plate with an original oem part that had 50k miles. Got the correct trans fluid level, and reset the computer with the battery terminal trick. Tried driving, still in first gear, the engine light on. Anyone have a clue?
