I have owned a 1999 Jeep Grand Cherokee for about four years now. I love the thing but have been experiencing a lot of problems with it over the past few months. At first, it would just shut down while driving down the road. It didn't spit and sputter and then quit, just a clean and quick shut down - almost as if the key had been turned off. Sometimes it would fire right back up, other times it would only crank but not fire. But it always started back up after a few (15-30) minutes.
About a month ago, I paid almost $1,000 to have my computer replaced. It was running really rough, missing and sputtering, and the check engine light was on. Every time they hooked it up to read the code it would show a different code but all were related to a cylinder misfire. The number of the cylinder would continually change though. After checking the coil pack, spark plugs, etc, the mechanic said it must be a bad computer and replaced it.
Since then I have had major problems getting the thing to start at times. I can leave the house in the morning and it will start fine, stop and start the car several times throughout the day with no problems, but then - BAM - it will refuse to start. Again, it will crank normally but never actually turns over and fires. After waiting a few (30-45) minutes, it will start right up as if nothing has happened.
I've taken it to several mechanics, but each tell me they have no idea what the problem is. Any suggestions would be a major answer to prayers and greatly appreciated.
