I'm up to 8 cold starts with no probs since putting the Metro's coil back in.

I need to take it off & clean the valve &passages.

Bad, very bad. Had an egr that was slow to close, would die everytime it came to a stop. Finally figured it out when I logged engine parameters on a drive. IAT shot to over 250° in mere seconds, only thing that gets that hot is.... exhaust.
