i have a 94 toyota 4x4 with a 22re engine and it bogs teribly when the engine is starting to warm up. i have adjusted the tps to the specs it is supposed to be at but still a problem. when the engine is cold the truck runs with full power but as the temperature rises the truck runs out of power with lower power to acceleration and driving abilities. i dont know what the problem would be and if it would be related to the auto tranny? could it be fuel injector leaks? could the computer be goin bad? please help me im stumped. i have been trying to figure this out for months. thanks
