could bad spark plug wires cause code 15 to come up? reason i ask because my tach is goes nuts and the car backfires and then dies,...i pop the hood,..pull out the spark plug wires and than put them back in,..then i reset the ECU and the car is fine for awhile and then it starts doing it again,..i just replaced the coil about a month ago also

 

check dizzy
you might have a loose rotor

 

any other ideas?

 

Your ignitor is going bad. All that time it takes for you to check the spark plugs gives the ignitior time to rest to start again but then it dies. That **** was happening to me, pissed me off.

 

Kind of sounds like a bad coil. Secondary winding is prolly ******* up. Or ignitor is messing up.
