sorry i forgot to mention that i had a problem about 3 months ago i lost my keys so i got a 95 bonneville ignition and key and had the vats taken out of my chip.but then i had a problem with the chip not advancing the timing and i had a new prom put in about a month ago is it possible it would work for a month now start acting up? when i have the problem i wait 5 minutes and then it will start. it only happens once in a while like every 50 starts.
