Two problems related to power train have been reported for the 1997 Jeep Wrangler. The most recently reported issues are listed below.
I bought this 1997 Jeep Wrangler from a used car dealer in June 2002 with a limited warranty and was told the vehicle pased inspection and had no problems. Since then I have had to have the wiring harness repaired, the fuel pump replaced, the transmission replaced, it has a faulty fuel gauge reading, the intake and exhaust manifold need to be replaced and now the steering linkage or stabilizer bars are faulty.
Powertrain control module failure. Vehicle shut down without warning on several occasions but would restart after a few minutes. On last instance, when vehicle was restarted, the engine went to 3000 rpms and would not return to idle.
