1990 ford ranger misses after warm up?

Engine dies and services light comes on, wait a few minutes and runs again

EASY and CHEAP! Take about $20-30 to any oil change place and have the IDLE AIR CONTROL VALVE removed and cleaned up al;ong with the THROTTLE BODY! USe MOBIL ONE 0W-30 oil and BOSCH or ENSO iridium plgus and expect up to a 20% improvement inpower and economy! GOOD LUSK and BYE NOW!

Possibly a cylinder misfire, once it acts up start unplugging injectors one at a time (plug each on back in) to power balance the engine and locate the problematic cylinder

This is heat related. Check for fuel and spark when this happens. If no spark ignition module is acting fine cool but when heating up it acts bad until it cools off. A bad crank sensor will do the same thing. If you have spark then the fuel pressure needs to be checked. Easy way to test fuel pump is to spray starting, brake clean, or WD-40 fluid into intake and try. If she starts and runs as you spray then your fuel pump has over heated and only works when cool.

  • What do y'all think of a ford ranger pickup 1990? I'm interested in a 1990 ford ranger pickup truck. It is a four cylinder and 5 speed truck. Do any of you have any good experience with these trucks?
  • I just bought a 1990 Ford Ranger and it is doing something weird? As stated in the title I bought a 1990 Ford Ranger today and it had recently gotten some parts replaced including: Fly Wheel, Starter, tires and some others. But the problem is, when I'm stop and accelerate the whole truck shakes and jiggles and I'm not exactly sure what it is? Any comments help. It's a Ford Ranger 1990 Automatic 4wd. Also, I'm not sure if this is normal on these old of cars but when on the freeway going about 65 that's red lining it.
