Chevrolet Repair: 86 chevy cavalier bogging out, tcc solenoid, camshaft sensor

Question
86 cavalier idles but cuts out when gas given. I broke down and had the ecm replaced the other day. This is a RS 2.0 model with automatic trans and a/c. The car remained running but bogged down not allowing acceleration. It would start back and idle normal but when gas is applied a bogging sound is heard and rough idle appears then the car cuts out. If the gas is release the car most of the time will remain running at normal idle but will ruff idle sometimes. The car ran fine for 3 days after the ECM was replaced. Now the car did the same thing and will crank but stalls when gas is applied. I have cleaned the injector, it is ejecting gas. I replaced the plugs with bosh 4+. Also I replaced the fuel filter, plug wires, O2 sensor, temp sensor, distributor cap and rotor button. I have checked and replaced any vaccum tubing I have seen. May have missed something. I just purchased this car for my mother and do not know its history. When it runs it runs perfect. Any advise will be apreciated. I have seen some people say the camshaft sensors can cause this type of problem but I want to do as little shot gun replacing of part as I can, but do not mind replacing thinks that may be worn out anyway. The car has about 150,000 miles. thank you.  

Answer
hmm try the egr vavle and then check the tcc solenoid, one or both might be caueing your problems.  i doubt a camshaft sensor is the prob but i would start the cheap route and work up to camshaft sensor. hope that helps if you need more insturction on how to check the tcc and the egr e-mail me at renagade25sb@yahoo.com
