Three problems related to car stall have been reported for the 2004 Jeep Wrangler. The most recently reported issues are listed below.
The vehicle had been driven for about 35 minutes at approximately 70mph on the interstate. The vehicle unexpectedly began to produce a thick white smoke. The vehicle was immediately pulled over and placed into park; the vehicle was already on fire upon exiting. The grass beneath had caught on fire as well. The hood began to blacken indicating a fire in the engine compartment close to the firewall. The entire incident took place in about thirty seconds; from the time it began to smoke to the time it was on fire begin the entire incident. A truck driver with a dry chemical fire extinguisher put the engine fire out; after lifting the hood to a ball of fire. The only injury begin light burns from lifting the hood. Essentially, my Jeep Wrangler, with no aftermarket parts installed, burst into flames for no apparent reason.
Hard starting and stalling. The vehicle will crank and crank and will start sometimes or you must turn the key off and try to restart, and will start the second time, but usually runs poorly for a few seconds. Will sometimes stall when puttin into gear. Dealer has changed fuel pump and put a shield over one of the fuel injectors. Still having the hard starting problem.
2004 Jeep Wrangler sport with 4. 0 I-6 engine. Would stall after complete warm up while idling in gear. Dealer installed heat shield over fuel injector, but still have stalling problems on cold start. No lights or anything come on. Only had 400 miles on it when first occurred. Now, at 16000 miles, I'm having stalling on cold starts in warm weather only. In the winter, the vehicle runs great. Dealer cannot recreate the problem, and do not know what to do.
