2004 Jeep Wrangler Problems

Water can leak near the A-pillar, at the front edge of the driver and passenger side doors. An improved seal is available.

The throttle position sensor (TPS) may fail causing intermittent drivability problems like hard starting, stalling, and/or hesitation when accelerating. A failed TPS will require replacement, proper diagnoses should always be performed before replacing any parts.

Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Leakage from the transfer case normally occurs at the case-mating surfaces and require removal of the transfer case to reseal.

2004 Jeep Wrangler Questions

Missfire code p0300. On excelleration gas pedal clicks medal on medal and does not excellerate properly. Engine light is on and sometimes blinks.

After driving at highway speed my oil pressure gauge sometimes goes to zero when I stop. It never does this if I put it in NEUTRAL as I roll to a stop. I replaced the oil pressure sending unit
and it stopped doing this for a few weeks, now it's doing it again.

Can I download data from RepairPal to my computer? I want to backup the data.

I have a 2004 jeep wrangler 4 cyl,.5 speed. It just shut off,.everything seems to be O.K. but there is NO fire going to the plugs. Please advise,.Thanks, Ben

2nd best Jeep I have ever owned. The best was my '86 CJ-7. I drove it forever. It had nearly 300,000 on it before loosing compression to the point that I could no longer get up to highway speed with it. Traded it in on an 04 Wrangler. Re-geared it to 4.56, ox lockers front and rear, 4.5" Rubikon lift, slip yoke eliminator with a rear cv shaft and I can go anywhere my 33's will take me.
