32 EGR system failure?

thanks for the help
if any body needs anyhelp with computers or networking please let me know

 

11-Check your sensors and wiring to the sensors. Pull them and make sure they are clean and free of debris. Also inspect the timing belt. How does the car run?
12-nothing to worry about
21-more than likely it's your upstream sensor failing or has a wiring problem. Sensor may need to be replaced.
22-inspect sensor and wiring. May need to be replaced
25-pull the IAC and clean it up real good.
32-EGR valve is probably stuck open. The EGR valve and transducer should be replaced as one.

It would help if you got the car scanned and got the "P" code to narrow down your problems.

Tell them that 95's are OBD II compliant. You can get it scanned.
