chevy c1500 4.3L been running rough for a while. since I am having a lot of trouble with other vehicles, I have to try to get at least one reliable, this is the only vehicle Ive seen that has a "check gauges" light, I assume that is the high temp, but that usually will cool back down without doing anything Im guessing a sticky thermostat, but when it really starts coughing, it shows a check engine light and is not usually associated with the temp. I dont see where to hook up a scanner, and I am guessing its too old for the obd2 scaner, any help for me to start?

usually retarded timing will cause and engine to run really hot

and that is usually caused by a bad distributor which when they go back will retard the timing and cause these drivabilty issues

if the basic things of plugs and wires are good and the fuel filter is new or newer then most of these installing a reman distributor will correct these type of issues

auto zone just gave me a chevy key with two probes to bridge 2 points and get a code to flash, but i dont fully understand where to put it or how exactly to read the code
Customer reply replied 11 months ago
can I look at the cap to know first if this is happening?

turn the key on and jump terminals A to B at the aldl connector and count the flashes for codes

the issue is the pick up coil and the module inside the distributer its cheaper to just swap it out vs changing those parts alone in your old distributer
