part throttle power loss after engine warms up
96 Taco 2.7 5spd 4x4 runs just like a new truck right up until the temp gauge reads normal operating temp. After the truck is warm I loose power and and there is a part throttle stumble like it is starving for fuel. I have been chasing this for a while and followed multiple mechanics recommendations.
Cleaned throttle body, cleaned MAF, new O2 sensors, new coolant temp sensor, new plugs, wires, cap and button, new fuel filter, air filter. I take care of the truck and treat it to Amsoil front to back, Wix filters all over, lube the damn thing regularly but this is kicking my ass. I have access to a really good scanner so if i need to pull data let me know, I have done it before but dont know what the limits or numbers should be so it's pretty much pointless until i can find reference numbers.
Thanks in advance

the only code I have thrown is for the front O2 sensor, and i am sure that was caused by the cracked manifold, I replaced the manifold with a header , code cleared no problems.However I blew a collector gasket and the code came back, same code, front O2 sensor. I am driving around still and have yet to clear the code again until the new sensor is proven to be needed. I replaced them both a month ago and no difference in anything. But to answer you, drives the same , CEL on or off, really great until its warmed up. Thanks
