Ok, it's hard to explain, but I'll give it a shot.

6 months ago I changed a belt and bypassed the A/C compressor. Summer is hot, so I bought a new belt and routed the A/C back in. I recharged my A/C 2 days ago, and no problems...Driving the car today with the A/C on and the car started lagging. I turned the A/C off, and it kept doing it. It acted like it couldn't breathe.....like a person when they cant catch their breath. It ran fine at a steady cruising RPM, but as soon as I'd give it a little gas, it'd "choke" again. I let the car set for an hour or so, and took off to my nephew's birthday party (with A/C on). On the way there, it does it again. So I turn the A/C off and lope to their house.....car sets for a couple hours and I go home. Didn't use the A/C on the way home, and the car didn't "choke" at all.
I picked up some Sea Foam and dumped half into the vacuum line, and dumped the rest into the tank. I'm hoping this will fix the problem, but I doubt it. It seems to me like it's more of an air problem....like it's getting hot and not getting any.

Anyone else have this happen to them, and if so, what was the problem?

maybe you need to clean ur injectors
