Bucking/Misfire only at idle

recently i replaced my icm and ignition coil with a auto zone replacement. it seemed like after the replacement my 93 lude started to misfire and do this weird bucking thing when I'm idling and when it does misfire the rpms are normal. After doing an inspection to see if i could find a problem i noticed my axle had beed rubbing on my o2 sensor wire and it totally cut one black wire in half and worn another black one down to the bare wire. i reconnected the wires and the car still has the problem. *I'm pretty sure there is no vacuum leaks*

the only thing i can think is wrong is the auto zone parts are not as good as the factory parts. can someone please tell me if they had a similar problem

Re: Bucking/Misfire only at idle

do you still have the old coil? if you do swap it with the new coil start the car up and see if you still have the problem. if you still have the problem return the icm and get a new one then try again

Re: Bucking/Misfire only at idle

ok just return both and get new ones from them. just say you think there is a problem with the parts and you want to exchange them.

Re: Bucking/Misfire only at idle

is it only audible, do the rpms drop? does the motor itself sound like its misfiring or bucking?

Keep us updated because my car is doing the same thing but it started out of nowhere, and its only audible, so driving, no misfire, when idling it misfires but rmps dont change and motor deosnt sound like it is..

i have got it down to it either being
a. injectors
b. fuel filter

I replaced my wires, replacing spark plugs tomorrow, i had an egr code i was hoping it was that, but i cleaned the egr valve and it still presists..

Re: Bucking/Misfire only at idle

I have the same misfire issue at idle. Was throwing the heated o2 cel. Replaced it and was still misfiring until about 2 days ago. Now my idle fluctuates up and down. Reaaallllly annoying. Gonna check for a vaccum leak when I get some time.

Re: Bucking/Misfire only at idle

i already exchanged my icm once and it still does it so i guess now it will try to exchange the coil but 95bb2 let me know how it runs after you change the plugs and wires... i had this problem before and it was the wires but i just change my wires last year for some bosch wires and did a full tune up cap/rotor/fuel filter plugs and wires, so unless i already have a faulty wire i don't know what the problem is.

Re: Bucking/Misfire only at idle

Im pulling my spark plugs out today to see if they are fouled, they are less than a year old but I have ran sea foam through the car and its said that they can foul the spark plugs, if they look bad I'll replace them. If that doesn't fix the issue, I'll be replacing the fuel filter next then the injectors, I will check back as soon as I'm done.

Re: Bucking/Misfire only at idle

So here are my old spark plugs:


So I went ahead and replaced the plugs with ngk iridiums and the misfire/sputter has evened out, I can still hear it, but it's not as noticeable, keep in mind I'm running the car with no exhaust after the cat, so it was a lot worse before, you could hear it and feel it on the floor board, now you can't feel it anymore but you can still hear it very lightly, I'm going to go ahead and replace the fuel filter and go from there.

So far I have:
Cleaned EGR, IACV, PVC or whatever valve
Replaced spark plugs and wires
Seafoamed the car

I'll keep u updated, let us know how its working out for you.

Re: Bucking/Misfire only at idle

alright guys..i think i fixed the problem. faulty Spark plug wires. today i went to auto zone and was like since I'm here i should just ask about the warranty on these wires. it turns out that they have lifetime warranty so i switch mine out for some new ones and so far the car hasn't jerked at idle.
