[QUOTE="Dirty Dog, post: 451366, member: 24042"] The automotive equivalent to "unplug it and plug it back in". Works more often than you'd think. Your buddy has air and fuel (since you sprayed it), so that leaves spark. The P0688 is a low/no power to the ECM condition. Worst case, that could mean the ECM is failing. But more likely it's the ASD relay. The P0222 and P0123 are TPS codes, but I wouldn't worry about them yet, since the throttle body seems to be responding properly. Make the ECM happy, and it may well make the TPS happy. [/QUOTE]
