hey guys!
my 99 toyota gave me an check engine light for a bad tps sensor, truck drove fine though, took it to my mechanic and he verified the error and replaced the sensor and cleaned the throttle body, drove it 10 miles and the check engine light came on again for same error, truck still drove fine, mechanic put the old sensor back in and it errored, put the new back in and NO error, said if it happens again, looking at replacing the Throttle Body! well it came On again and now is driving rough when you try to accelerate almost wants to stall. Question: how do I know it's not another sensor MAP, or MAF etc...... going bad. hate to buy this high priced throttle body and get the same results! Whats my options here? Apparently its not the new TPS sensor alone. What is the problem and my options?

Try cleaning the MAF sensor with an electronic cleaner CRC and see what happens
