Check Engine ON, what can you use as a code reader

[theboogins]

Is there a trouble code you can read from the ignition or do I have to go to the dealer to get a read?
O2 sensor?
Thanks.

Depends on the year. Before 1996 you can do a "stomp test" (search for that on here). 1996/97+ you need to buy or borrow an OBD-II code scanner or "scantool".

Something about Pedal position sensor? Anyone?

Never mind-read the code wrong-O2 sensor, right?
Hard to swap?

Not difficult to replace. Order oxygen sensor from cmuzyy, rent sensor tool from Autozone or some place similar, soak old sensor in PowerBlaster to aid in removal.
