Can this be a vacuum leak? The difference between normal and bad are extreme. I mean it has been running and shifting fine for the past month, then I started it up and the idle immediattely dropped down and then back up and stayed normal. But when I pulled out of the driveway, it shifted like I had it to the accelerator to the floor but I was driving normal. Crusing around town at 30 MPH in first gear is not fun. So what is my problem? I got a MAP sensor code the day before I started having problems, but I changed it out before and it didn't fix it. It has plenty of power and is idling mostly normal. PLEASE HELP! Thanks.
Oh, my heater also stopped working. I was able to beat on the black box under the glove box and it would start working. Then it would run real slow even on high. Now it won't come on at all. Any ideas?
Also, I drove my Jeep back to work from lunch today and instead of babying it like I usually do when it is running like this, I drove it hard and let it shift on it's own at 4000 - 4700 RPMs. By the time I got back to work, (about 5 miles), it was shifting fine on it's own at around 2200 RPMs. I would really like to know what is going on.
