Stumbles only at certain rpm, bucks terribly
91 22re pickup, only stumbles at certain rpm, idk exact rpm because of no tach, but very slightly above idle it cuts out and stumbles as long as you hold it there, but runs fine above and idles fine.. I have a Toyota tech for 40 years stumped on this one. Already tried basic plug, wires, cap, rotor button, fuel filter, timing is good( mechanic told me) egr is fines, o2 sensor is new. Tried another used afm. Checked for leaks. Unplugged tps and no difference. Doesn't matter if it's warm or cold out. Or how warm engine is. Thinking about trying a new ecu? Just got the truck couple months ago, it ran like junk when I bought it. I can't even drive it in public haha. I believe it was a beater before I bought it, so could have gotten ecu wet? Just my idea.
Edit.. Unplugged my purge hose from my charcoal canister and wallah. Runs like new
