Poor Idle, Engine Stalls, Hesitates on Acceleration on Ford Tempo

Sludge build up in the throttle body can cause a poor engine idle, stalling, and/or hesitation. The correction is to install a new idle air control valve spacer kit to prevent the sludge build up, set the base idle, and clean the throttle body.

problem details
1991 Ford Tempo 79,000 mi,
my car stalls while im driving or at a stop light. it does it more in the summer time than in the winter but i had my cam sensor replaced a month after i bought the car so i dont think it's my sensor.
1994 Ford Tempo 99,000 mi,
I had this intermittent stalling issue that happened more in the summer than any other time of year. I was at my wit's end. My long time mechanic retired due to health issues. I ended up going to 12 different mechanics before solving. Insist on diagnostics! Ultimately, I had a underperforming on the edge of failing fuel pump. Everyone kept pushing me to the "spark" side and basically threw parts at the problem. Either the state of mechanics being able to troubleshoot and diagnose issues has declined or I got more than my share of less than honest service. Out of the 12: 1 refused to work on my car, he said he was too busy to diagnose (was kind of a jerk), 1 was honest, he said he couldn't get the car to stall and he refused to "throw" a part at it and hoped it worked, 1 guy ultimately fixed the car, the other 9 were crooks.
