Having problems with your 1998 Jeep Wrangler ?
98 jeep wrangler 2.5L #4 misfire
\015 I have a 1998 jeep wrangler 2.5L. #4 cylinder is misfiring I have checked the spark all good there. Cylinder seems to have godd compression.I changes out the injector just because i had one. No change, still misfiring in #4 cylinder.I guess I better verify that the injector that i put in is working but I'm almost positive that it is. Not sure what's happening. I added an additive to the fuel and then this seemed to start. But I wonder if it was just a coincidence. It's called DEHA an amine it's an oxygen scavenger produces nitrogen and hydrogen. not sure if it is reacting poorly with the gasoline. And for some reason causing #4 cylinder to misfire. Appreciate any help,Steve Hansen\015
