Is my Cam causing my Problem?
I have a 383 stroker motor in my '87 Camaro (was an LG-4 with 4bbl.). I am still using the CC Q-jet and all the SMOG equipment. I have around 9.5:1 CR and my cam is a GM 383HT Cam. Its specs are .431/.451", 196/206 dur@0.050", 109 LSA. Everytime I give the car alot of gas I get a check engine light, same thing happens when I have been driving along time and when I lift off the gas I get the same check engine light. Both lights will go off when normal driving starts again. The code I pulled is 32.
I have everything plugged in, could my cam be the problem? I am worried that the cam's 109 LSA is too much. Someone suggested I switch to a ZZ4 cam. I need to pull the motor again anyway because of a broken oil ring. Any help is thanked in advance.

That code is for a Barometer sensor fault. Check first to make sure you DO NOT have a vacuum line attached to it.

Thanks for the reply. I looked it up in my Camaro manual and it says its a differential pressure sensor. Is that the same thing you are talking about?
I have a vaccum line running from a manifold port to the MAP sensor (passenger side). Then I have a another thing that looks almost like a MAP sensor on the driver side. It too has a vacuum line running from it to a port on the back of the carb. The vacuum lines are all routed the way the chart told me to. If there is something I should change, please tell me.
