Help! Hesitation right off of idle.

[John Robinson]

Follow the yellow brick road

I just went through a period were I was getting DTC26,55,64,63,72. I naturally started to run the diagnostics for each one and gradually I started to eliminate some of them only to have the Service ASR come on with the DTC26.

I went to the Service ASR section of my FSM and noticed that the tps was connected with several systems and they shared a common ground. I was able to correct all of the codes by checking the fuses and I discovered that the ENG1 fuse was blown and that the car was running on ENG2. Replaced fuse and all is well again.

You guys are describing some of the symptoms I'm experiencing. I had a code once, but I shut the car off and started it back up and it never came back. The car does shift hard both into gear and while driving. The gas mileage is slightly below average. The fans come on way early. It starts hard in warm weather, then idles rough until something kicks the idle up. Sometimes it pulses a little bit when I'm sitting in traffic.

I need to check that TPS out I suppose.

Even though the SES light may not be illuminated, the ECM did store the code that set it. You can easily retrieve any codes. I would suggest finding out what code was set. If you need help with retrieving let us know.
