Ok, I just got my first Toyota in August. 1992 4WD P/U 22re 5 sp. Truck always runs good when cold. Runs good most of the time when at operating temps, but SOMETIMES the idle will drop to 300-350rpm. I tried plugs(NGK), wires(NAPA), rotor button and distributor cap. Still does it. Truck has 234K on it but it isnt the original motor. Any ideas?

Just got my new set of 30x11.50 Swamper SX's mounted today. Garage aired them to 35 PSI. What would you figure to be the optimum pressure to run. Figure 35 is a tad high. On an 8" wheel BTW.

 

I would clean the throttle body then adjust the idle up. As for the tires drop them to 30 if 35 seems to high for you. welcome to YT
