1984 camaro, newly rebuilt transmission after sitting for 12 years, less than 1,000 miles after rebuild. rebuilt carb, replaced gas tank and fuel filter a few months ago. took smog pump off and put new valve covers on. about a month ago I started noticing it was being real sluggish during acceleration. replaced the fuel pump and it fixed it right away, it was running fine and that was about a week ago. over the weekend I put seafoam in the car and noticed better acceleration. last night and this morning I noticed it being sluggish again, I know it is happening because I can't get above 3,000 rpms and 70mph. any ideas on what it could be or how to figure it out, also use premium gas all the time so small chance for bad gas
