Question about 1995 Jeep Grand Cherokee
I have a 1995 Jeep Grand Cherokee 4 liter automatic that I purchased new. My problem is that when it is really hot (and it is in Kamloops where we live ) and the air conditioner is on, after a while maybe half an hour the engine quits. If you try to start it again it misses and black smoke pours out the exhaust, but if you let it sit for 10 minuets it runs fine. I have had this into repair shops and dealers from new and nobody can solve. To date I have replaced the fuel pump and complete distributor, Any suggestions? Thanks Harvey
Hello, it sounds like the ECT (engine coolant temperature sensor) is failing, the sensor communicates with your computer and has affect on fuel usage, it is common for bad sensor to allow too much fuel and cause cylinder flooding, this in turn will lower cylinder compression and cause miss, black smoke, check engine lights, easy too overlook without propper diagnostic equipment, easy too change and fairly cheap! good luck, marty
