Question about Jeep AM/FM Cassette with CD Changer Controls - Upgrade Swap
I have a 1997 jeep cherokee sport, 4x4, with 4.0L motor. i would like to know what would cause the number one cylinder to miss fire, also what would cause it to multiple misfire. I have replaced wires plugs, cap and rotor along with the distributer. please any suggestions would be greatlly appreciated.
Fill up the gas tank and add some fule injector cleaner
that solved my problem with misfire in cylinder 1
took about 2 days and my engine light went back off
i used a brand called
lucas fuel injector cleaner
i got it from advanced auto
auto zone also carries it

I have a misfire in cylinder #1. I have had the spark plugs, wires. coil pack, and upper intake gaskets replaced and the engine still has a misfire in cylinder #1. When I replaced the coil pack it was ok for about a month. I tried the Lucas fuel injector cleaner and it seems to be fine until the gas runs out. If I don't use it again my engine starts sputtering. Oh, I forgot to mention that my engine sputters really bad. The engine light is on as well. Could this be a dirty injector and if I continue to use Lucas cleaner will it clean all the junk out of my injectors? Like I said it seems to be working. Please help! Thanks.... kthompson
