1997 GMC Jimmy - Page 6 Questions & Answers
Key is stuck and everything is dead
Tried moving the steering wheel firmly in one direction or the other while (gently!) attempting to turn the key? Or look for a little lever that your knuckle sometimes hits when you do turn the key.
Why do i have oil in my antifreeze
Transmission cooler inside the plastic parts of the radiator may be leaking and causing the oil to mix with the coolant. GM also has a problem with their lower intake gaskets leaking, which would allow the oil and coolant to mix. Last possibility is the head gasket is leaking and mixing the oil into the coolant side but not the other way. Check your transmission fluid for mixing evidence. Another thing to do is pressure test your cooling system (Radiator, hoses ect) to see if there is a leak. Another test to try out is compression.

Codes po 141 & code 155
If these codes only show after rain then the moisture is affecting the connections in the wires. Pull each connector apart and clean out with wd-40 or other water dispersant and ensure that the connections are water tight. Any dirt ,oil ,grease green gunk on the pins will cause a problem
