Spark Plug problem
Hey guys, i know this isnt the 2.3 section but i dont feel like waiting forever for a response and this problem isnt limited to just the 2.3. k my car has been running kinda sluggish compared to normal and my check engine light has been coming on more and more often. I took the caps off my coil packs to check for spark from each one. And i noticed 1 doesnt spark at all, and another barely sparks half the time. Luckily i have 2 park plugs per cylinder so my car still runs. Would this mean that theres a problem with my coil not the spark plug? Also if i replace the coils should i do all my plugs and wires too? or just if they really need it. thnx

RE: Spark Plug problem
k thanks guys, guess i'll head down tomorrow and get one ordered in. I'll do wires while i'm at it but i wont bother with plugs, they werent bad. Does it matter if you only replace one coil if the other is fine? One nice thing about the dual plugs per cylinder is that i broke a wire today when i was trying to take off the boot and i can still drive it fine

RE: Spark Plug problem
Alright guys, i replaced the coil that had 2 spark plugs not firing and i replaced all my wires. WHen i finished i assumed everythign was fine (didnt want to check cause of fear of getting shocked after my friends jeep kept shocking me). But my check engine light came on again and went away and came back like it did before. So i checked the plugs at the coils and the same 2 are not firing. I have no clue what to check now. and im a little pissed that i blew th emoney on a new coil when my old one was fine. What should i check now? What could cause it to work sometimes and not others? (the problem started out happening very infrequent, but now the light seems to stay on longer and longer.) Any help would be appreciated.

i'm not too familiar with the computer of the 2.3L, but if the coil didn't work, return it. clean it up like new and tell them it wasn't installed, turned out to be a different problem.

RE: Spark Plug problem
haha well the coil is brand new and giving me the exacta same problem as the last one, and because the fact that i work at the auto parts store where i bought it i dont think i can return it.
