I have an 89 sc 5spd with 79k miles. When car is cold it wants to stall when I come to a stop and push in the clutch. After it warms up it's ok. Also it seems to bog slightly at wot in 1st and 2nd gear. It pulls hard up to about 3000 rpms and then starts falling off. I just replaced the plugs and wires, and the cats are gone. Any help would be greatly appreciated.
