Have you upgraded to a performance chip. I have seen this happen with some Stage one or Stage two chips. If you have you may want to look into getting a chip written just for you car and whatever(if any)modifications that you may have made. I can't promise you that I am right but my bet would be i'ts in the CPU somewhere.If you find out anything else let me know and I will try to go from there. Also If you have completed any mods. at all include that also.And if you have upgraded to a performance chip let me know which chip.I can't promise you anything but I will research it the best I can and try to find you an answer to get you car running better.
