Engine Mechanical problem
1997 Jeep Cherokee 6 cyl Two Wheel Drive Automatic 121800 miles
I need some advice. I just bought a used 97 Jeep Grand Cherokee Limited. It ran fine but I was told the exhaust manifold was cracked and the VIC said "coolant sensor bad". I took it in for an oil change and to replace the sensor and replace the serpentine belt. The mechanic told me the sensor was fine, but it was running too cool so probably a bad thermostat. Turns out there was no thermostat in the jeep at all and the housing was in bad shape. So they installed a thermostat and a new housing. Now it runs rough, the "service engine" light came on. I took it back and they told me it may take 3 cycles of running for the computer to reset itself with the proper levels. I drove it around for a while and now I have bad exhaust fumes inside! Especially when I run the A/C. I know I have a crack in the exhaust manifold but I didn't have the fumes before todays fix. Any ideas what could be causing this?
have the same problem?
