93 Ramcharger help

Try waiting for a dark rainy night. Start it and pop the hood, look for a light show around the ignition system.

Are the connections tight and clean on the fuel pump? How bout ignition system connections? Use a multi meter and measure voltage drop.

How do the plugs look? They have some miles on them now, pull them one by one and inspect for fouling. What are they gapped at?

Go ahead and replace the airfilter for the hell of it.

Check all sensor voltage readings with a multimeter and see if they're in spec. For that matter is it throwing any codes? Do you know how to pull codes? You dont need a scanner to do it.
