Drove into driveway, thought fireworks odor had followed me up hill - until I tried to crank it later - cranked but didn`t fire. Found this crisped connecter unit - resistor/condenser near coil module, left fender which wiring diagram identified by wire colors. No obvious short as best I can determine by ohm meter. Any experience with this? Car is stock except for cold air/headers/pipes which have been a pleasure for 30,000 miles. Had some overheating due to coolant leak but not enough to fry anything else.
