Mechanics

CHEVY S-10 168,000 MILES 4 CYLINDER ENGINE / GUAGES

1987 Chevrolet Blazer

My daughters truck has a manual guage in dash set up. The temp. And oil pressure guages go way up and down randomly. It is hard to start some times.I have paid two different mechanics to replace the following parts; Oil sending unit, temp. Sending unit, ac plug, thermostat, tuneup. It runs ok once started.(Guages allways act wierd )I also had a new air conditioner install which comes on only when it wants to, no fan action at times. Any help would truly be appreciated !
Thank you for your time.

If you have gauges that are twitchy and other interior items work intermittently then it might be a bad/poor power or ground
