Not again...

Coming home from school, service engine light came on again also the car has a rough idle at 500rpm(when at a light etc). I have a feeling its another ignition coil but not sure.

Sounds like a classic case of weak coil to me

x 2 on a weak coil. Pray for a front bank!

brought it to auto zone to do a diagnostic, guess its the number 5 coil this time.... brilliant. so the car is going in the garage friday, and hopefully thatll solve it.

Personally I think one should just buy 4 new ones and put them in the back. Then you can play the shell game with the used ones in front when the time comes.

You should also be careful when removing the front engine cover that all the little steel rings that support the plastic cover at the bolt holes are all still there when reinstalling. Or better yet keep track of them when removing the cover.

during the summer when i have more money ill buy 4 more coils and replace the rest just cheaper to do one at a time now since im in school.

im usually very organized when im takeing parts off, i tend to have a jar next to me and place all the nuts and bolts in there. plus i keep a count on how many they were.

It's easy to miss the small steel rings as they are not suppose to come out, but do occasionally.

Don't drop those into the cylinder when you change plugs, clean the intake, or replace rear coils.
