Better, but sputtering after plugs and coils changed


Recommended Posts

Changed all 6 plugs and coils and it is much better, but the CELis still on and there is some sputtering.

Before the noticable need for coils there was no sputtering.

On the last coil, which didn't want to cone out, the metal was white, not shiny & silvery, and it left the cylindrical wall the spark plug goes in dis colored, compared to the others. Could that discoloration be the cause?

The plugs supposedly come pre-gapped so I didn't alter it, and the plugs were carefully cloud down the tubes, not dropped, using a magnet. I felt the coils seat it's rubber boot on the plug so they went on all the way.

How bad would it be to drive about 100 miles with the sputter for a few days if I can't solve this problem today? I don't have a Durametric to diagnose the car, and there is no auto zone around here.

It is possible that you have a problem with the wiring feeding the coils; those are know to get brittle and cause problems with shorts. Or bad grounds. But you really need someone who can not only read the codes, and knows how to decipher them, AND has sufficient diagnostic skills to find a problem in the wiring. Sometimes just moving the wires around gently can cause a short or bad ground. My friend's Audi with 100k miles had similar problems last week, and not only did it have a few bad coil packs, but the wiring to the coils was literally crumbling...like it was 100 years old.

Also, driving a car with a misfire is NOT a good idea. And Autozone may have a very basic generic OBDII scan tool, but that's about it.

PM with local indy tech info (with Durametric) Sent.

how bad are the hesitations? If its significant (pre det possibly) then that's no good....not to mention, what happens if you get out 100 miles and you break down?

but back to your issue.....you got the right idea, read the plugs....a wet plug is lack of spark......a white plug is a "hot" plug.....or possibly a lean condition.

Run the car up to temp around your place (assuming it is reasonable to drive) and then pull the plugs and see if you got wet plugs anywhere.
