1990 Ford Club Wagon XL - Help
We just bought this van 5 days ago and it has run great until today. We drive the van into town 18 miles and turn it off it, we have to wait for the engine to be totally cool before it will start again. The engine will catch and stall out with the check engine light on. This just started, ps we drove it into town with the temperature around 45 stopped had dinner at BK and thirty minutes later it would start and stall out, took the battery to Autozone and charged it...an hour and a half later it fires right up, and half way home the oil guage showes the pressure change and see below.
We put some risloan through the system in advance for an oil change, the oil pressure dropped from the middle of the word Normal in the gauge to the end of the word normal and the check engine light comes on. I turned the van off when we got home and tried to restart it and it starts and dies, the same as it has been doing all day.....
I know we need to tighten the alternator belt to get rid of the electric whine along with plugs, wires, cap and air filter. I am just really lost as to the other stuff.
