Thanks. Battery tested ok, and connections were checked, seemed to be in good clean condition. Reset computer using method found several places on internet: battery disconnect for 60 min, start car w/ all accessories off and idle for 10 mins, then shut down. Restart car with all accessories on, idle for 10 min and turn off.
Check engine light is now off, but 'wrench' light is on continually. From other info on internet, 'wrench' indicates throttle body issue. 1st solution is to clean TB. If problem not solved, guess I will have to take to dealer for trouble shooting. Even though Check Engine light is off, now have 3 error codes instead of over a dozen. 2 codes for o2 sensors, and 1 code for PCV. Info available thru other internet forums seem to indicate TB issues where wrench light is on, may cause codes w/o check engine light appearing. Does it seem we are heading in the right direction?
Other info also indicates the throttle system needs to be manipulated for the computer to 'relearn' throttle position once TB is removed and re-installed or replaced. How would I do this? Similar somehow to computer reset?
