Hey friends, I have a 99 Cobra and recently, out of the blue, I've been getting a P1233 and P0602 codes popping on me. It's strange because it runs great, and completely randomly my idle goes to hell and I can't give the engine any gas with out it sputtering to death and EVERY TIME I know it's about to happen because my right blinker pop on very dimmly. After sputtering for about 5 minutes it the blinker pops off and it goes right back to normal. I've seen a few things about these codes, from PCM to Bad fuel pressure but I can't seem to solve it. I just changed the plugs and injectors hoping to get lucky, and it seemed to have worked for a few days but it just happened again tonight. Car has a CAI and a custom tune using an sct tuner. I've had the same tune for 3 years without any problem until just recently. Any ideas??
