Got stuck and overheated now it will not rough past 2,000 RPMs. Change the O2 sensor, new injectors, new fuel pump, and new spark plugs.

Hi,

How badly was it overheated? Also, is the temperature gauge accurate?

Here is what I suggest. First, start by checking to see if there are diagnostic trouble codes stored. This has an OBD1 system and doesn't require a scanner to retrieve codes. Follow the directions in this link:

Do this and let me know the results.

Take care,

Joe
