1990 Seville sts

[joe5454us]

Just purchased a 1990 Seville STS and going through repairs: After air compressor was changed and dryer, the car shuts down while driving down the road, it starts right up while shifting to neutral and resumes travel for a few blocks them shuts down at about 35 to 40 mph. I am sure others have had this problem or similar. Please, good information or experience is always best. If you do not run the air the problem isn't there or hasn't been yet.

We have a 91 STS and use the A/C constantly with no problems.

You need to read the error codes and report back with them.

Get a pen and paper, then press off and warmer at the same time.

The panels will all light up to test the dots are all working then it goes through the computers and displays all errors that are stored.

Write them all down letters and all then repost.

Codes displayed B440, R026 (from History it stated). Then ended with, ECM?

Thanks Joe

I changed the TPS after reading a notice on All-Data about wrong TPS being on these cars, mine was wrong. Joe
