1990 Park Avenue, 109000 miles, 3.8l (non-Ultra). I have been experiencing a mis-fire (backfire) when downshifting under light load, usually when going up a slight incline. I have replaced plugs and wires, and, after noticing a more pronounced miss at idle (when the engine is warm), checked compression, which turned out to be ok (115-125 psi).
The check engine light has not come on, yet, but I was wondering if there is a way to interrogate the OBD1 diagnostic codes through the Climate Control Console? The code scanners that I've seen for sale all seem to indicate that they do not work with Climate Control systems, which this car has.
If it is possible to access the DTC's through the CCC, what are the "keystrokes" I need to use to do so?
Thanks in advance...
