Engine Cooling problem
1992 Toyota Pickup 4 cyl Two Wheel Drive Manual

hello! I'm have a timing problem. At idle it's 5 degrees BTDC, you touch the gas it goes 40 degrees of advance. At a stop sign it cools down, on the freeway it heats up. I have a new distributor and checked the throttle position sensor. According to the book it's good. Also the mass air sensor checks out good. I also put a new thermostat, water pump radiator cap, and eletric fan on. Any ideas??? Thank you and have a nice day!

Have had the radiator checked to see if it may be plugged or partially plugged?

Have you checked the fan clutch? Has the temp been checked to see what it is at the upper hose verses the lower hose at operating temp?
