Check the gas, could be water in it or drive the car with a fuel pressure tester connected to it and watch to see if you lose pressure.
Normal pressure while driving is about 30 to 40 psi

similar problems: After 20min cool down jeep was bucking/lurching that I traced to bad o2 sensor in exhaust manifold (which you've replaced is seems). The second problem of bucking/lurching, backfiring under certain driving conditions I traced to the battery sliding into the computer wiring harness, disrupting sensor input / output signals. I cured this problem by placing a 1" spacer on rear battery clamp, pushing the battery forward. Been years and no return of problem.

Just changed the 2.5L engine in my 89 jeep wrangler and the engine turns over but won't start it just backfires like the timing is off, but thats not adjustable on this engine. Where did i go wrong?


Have you checked the firing order to make sure the plug wires are in correct order. Sometimes an engine will run but rough if 2 wires are mixed but it could be that there's more than 2 mixed up.

1999 TJ Wrangler/Sah runs rough after warm


we have the same problem on our 2004 dakota. The mechanic says that it could be the exhaust vacuum that needs to be replaced. Also, they also mentioned that sometimes when the catalytic converter is plugged it acts that way also.

Let me know if this helps.

It does sound like a vacuum leak. Get a can of WD-40 and start spraying around the carb. It will rev up, and U can pin point the loose vacuum hose, are crack vacuum hose.
