Question 1) Where can i find the obd 1 sensor parameters for 1993 22re engine. I would like a manual or printout of the acceptable values and the high low range of all sensor parameters for the 4 cyl engine in my 1993 truck.

Question 2) obd1 trouble codes and their explanations for this 1993 truck engine.

Question 3) What type of scanner is out there for this engine, where do you buy on and or what options do I have if I want to scan the codes and to get a read out of the scan values and the codes.

Question 4) My recently purchased 1993 2wd low mileage truck gets gas mileage in low 20's seems it should be better any suggestions???
Thanks a lot

1) Search for the FSM
2) Look in the FSM
3) To the best of my knowledge, there aren't any code readers available or necessary: the ECU can report trouble codes to you via the check engine light. So take it to the dealership or paper clip & FSM.
4) My 88 4wd gets low 20's, my 91 2wd/auto gets mid/low 20's.
