INCONSISTANT RPMS AND BOGGED DOWN AFTER DRIVING FOR FIRST MINUTE OF THE DAY BUT ALWAYS SOUNDS GOOD AT AN IDLE. WHERE DO I LOOK FOR THE PROBLEM?

2001 Cadillac Deville • 135,000 miles

Does not overheat, but boggs down and recently I'm smelling gas fumes. It especially boggs down wbuthen I put a load on it. (20-30 mph max. Check maintenance light is also on. Recent repair about 6 mos. Ago for a similar problem. I think they replaced 8 intake gaskets of some sought.
Engine is a Northstar V8 32 valve.

Lots of issues with those gaskets causing vacuum leaks that cause similar issue. The gas smell concerns me. Get this checked asap. It may be just the converter overheating from running lean. It may also be clogged causing your issues.
