1. Check eng light on. 92 F150 70,000 mi. Owned since new. Has always been trouble free. 2, Mech replaced fuel pressure regulator. Now ok. 3. NEXT DAY tranny would not start out in 1st gear. Fluid way high with bubbles on the stick and seemed too hot. Drove back to the shop and of course when I got there it was shifting normal and the fluid level was ok. His computer had a code that said the eng computer was not reading 1st gear. He instaled a new solenoid and had the same code. Ditto for the 2nd solenoid. Waiting for number 3 now. I think he also replaced some electronic device on the transmission. Could he have accidently disturbed a wire or vacumn line while working in the area of the fuel pressure regulator? Seems too weird to me.

Where is the timing mark on a 1989 oldsmobile 88 royale brougham? I am trying to adjust the timing chain on my car and cannot find where to adjust it at.
