Thanks for the reply. I checked for fault codes 5 or 6 times during the period I was experiencing the engine miss. (both pin 8 and pin 14) No codes were revealed. Is it possible that a marginal coil could work well enough to not trip a code, but not well enough to prevent occasional miss during idle and acceleration? Also, the miss seemed to be more prevalent during periods of high humidity and after the engine had warmed up. Is this consistant with the "marginal coil" theory?

Thanks
