just want to inform everyone that aftermarket igntion coil are horrible i went through 2 already.
after i replace my oem coil pack with an aftermarket one my car still have a little bass bump while i am idleing at a stop light.
some time it one bass bump other time there like 2 or 3...
shouldnt have bought an aftermarket one....

 

bump bump bump for myself

 

what brand were they?

 

"standard" got it at the local auto store

 

just curious but how do you know it was your ignition coils and not one of your fuel injectors thats causing your problem?

 

i had the ses light that pop up and the mechanic did a readin with a multimeter and the ear test

 

if you didnt already, make sure you check the plugs to make sure that one or more is not fouled and causing the bump at idle. also make sure you coat the inside of the new coils with dielectric grease.

 

the spark plug is new and the bump is only an intermittent occurance....
it is really annoying though....
do i put the dialetic grease on the boot of the ignition coil or on the spark plug itself?

 

Finally after about 6 weeks of an occasional misfire at idle, the car threw a code. YEHAWWW!

During this period of time, I tested the coils both hot/cold. Did this about 4 times. All coils tested fine. Tested injectors and they were ok too. Even ran 2 bottles of Techron through th car. But it still had that misfire.

Finally the misfire became worse and I have a code. 0608, cylinder 1 misfire. Switched coil with cylinder 3, reset ecu, and yes! code 0606 comes up. Now I know which coil is bad.

Just went to slavage yard, picked up a coil from a 98 for $25
This will get me though until I order a new set online.

 

put a light coat on the side of the boot of the coil.

 

it me again problem is back again.
i read somewhere how our fuel injector on occasion go bad.
would a faulty fuel injector cause this problem of mine?
this is really annoying me.
thanks
mike

 

try a bottle of chevron techron fuel system cleaner to see if its a lazy injector. you may want to clean the throttle body too if its juttering at idle. see the how to on motorvate. ca, its very simple.
