I finaly got it figured out how to test the check engine codes and I recived a code 13 wich is the O2 sensor and the 33 wich is the MAP sensor wich is showing high voltage, anyone know how to fix this?
I know that I have to replace the O2 sensor because the wire got against the Exaust Manufold and my Cousin told me that if the wire coating is broken that the O2 sensor will be shooting a code.
This is on My 88 and I am unsure how to fix the MAP sensor Problem.

I just got done today with putting on a new water pump wich the old one was leaking about a Gallon of Anti-freeze a week.

Replace the oxygen sensor first, then clear the codes by disconnecting the battery cable for 10 sec. Unplug the electrical part of the map sensor (black part attached to the air filter by a clip). Now start the car until the check engine lite comes on. What code ya got? Remember it. Clear the codes again and hook the map sensor back up. Start the engine and make sure you have good vacuum going to it. You should. If not, follow and repair. Check codes and you should have a code 34 the first time. If you now have a code 33 and 34 then stop. You need more help. Let us know. Good luck.
