My car keeps bogging down and has even shut off while driving. Thought I would start with the spark plugs but I can't get to the back three, do I have to rock the engine or what? my car is also an Ultra.

Just bought it and guy who had it said it had a tune up with plugs and wires in the last year.

It just stopped going while driving with no warning of any problems. Engine runs good. Wasn't driven much for several years have had to replace some dry rotted gaskets and air intake valve is all. only 101,000 miles.

The key does not have the raised chip.

My brother was replacing 02 sensor when left on ramps for 3 days. Engine running fine now but when I drive a short distance the transmission stops working. Shut the car off give it a few min start it up and drive short distance same thing happens. Had filters & fluid changed. Still have same problem. I was told that is was most likely another sensor. Is this possible? Has anyone else had this problem?

fan is blowing but cold air only on drivers side and hot air on passenger side and rear vents

Every time it gets hot

Happens occasionaly with no warning when starting from a dead stop.
