My camaro just started acting up the other day and i have no cluewhat the Problem is. 1. When I go from park, to reverse or drive it bogs down quite a bit and kinda Shakes the car, about 800 rpm in park. 600 to 500 in reverse or drive. And when It put it back in park it goes up to 1200 rpms then back to 800.

2. If im in drive, no matter what speed, and I give it gas, it sputteres and my rpms raise and I hear a clicking noise in the engine, but after 2500 rpms it goes away. Or if im doing 60 mph and let off the gas, the just touch the accelorater a little bit, you can feel it shake, then it goes away after I let off the gas. One time i was at a stop sign and I punched the gas and it stalled out.

I already replaced the icm, coolant sensors, plugs and wires. The guy that owned it before me ran really rich you could tell by the spark plugs.

It seems to be really bad when it gets warm, which leads me to believe its icm again.

Also, i don't know if a bad battery would cause the icm to malfunction but my battery has died twice and I've only had it 75% charged, so could this be the issue? A bad cat? Or fuel filter? Pleasehelp me!!

Bad cats bad o2 sensors as well opti?

Well my opti was replaced 6 months ago along with plugs and wires. Only does this sputtering under 1900 rpms. I punched the damn thing at a stop sign and it just died. My fuel pump is reading 35psi and no ses light
