97 GCL 4.0 6 attempts to stall, idles rough, engine and abs light

First cold start of the day takes 10-15 seconds. Starts immediately afterwards. Sputters on some occasions on take off and I have to back off the accelerator and then press it again to gain power. Today it ran horribly at parking lot speed and oil pressure dropped to zero in gear. Also heard some random warning tone that did not seem to coincide with any lights on the panel. Soon after, my right front brake pads nearly burst into flames as if the caliper had stuck. I've changed the crack and cam sensors, distributor. I really don't know what to do here. Hoping it's not pcm

Suggest focus on the front brake pad issue until you get it resolved.
If you have a sticking piston/pad, that could cause all sorts of wierd driveability problems... but mainly the ZJ never really overheated pads in normal driving, and you appear to have something wrong on yours.

Can't think of how electrical gremlins could cause sticking brakes.

Thanks for the info. Looks like the rotor has definitely taken a beating so new pads and rotors for sure. Just wish the mechanical symptoms would present with more clues to a common cause. Pulling my hair out
