22re randomly bogging

[Wyatt_cato]

Absolutely stumped and you guys are my last hope lol! I’ve got a 93 pickup 2wd with the 22re. Randomly while driving the check engine light will kick on the truck bogs down and runs super rich. Sometimes it will completely die and take a bit to fire back up or the check light will turn off and power comes back immediately. I replaced the AFM pigtail, plugs, plug wires, distributor cap, and rotor. I would try and get a code for extra help but it only does it randomly on rides. Any help is appreciated thank you!

Could try unplugging the cold start injector just incase it’s being activated for some reason.

Bad O2 sensor? Clean IAC valve? Plugged fuel filter?

What is the code its throwing?

When was last time you replace Fuel Filter ?

Figured it out! Finally was able to make it throw a code for code 22. Replaced the coolant temp sensor and as of right now she’s running tits!

You were partially correct on this one. Coolant temp sensor was making the cold start injector fire when it shouldn’t. Thanks for pointing me in the right direction!
