Sorry for cluttering up CHR with this, but I hope someone here can point my in the right direction. My son has a '90 Cavalier w/a 134 ci 2.2, TBI, three speed auto. On acceleration from a stop, this thing bogs pretty hard. When you finally get up to operating speed, it runs good. It kinda feels like driving with a cold engine, but it happens at operating temperature. It starts and idles good, no smoke or odd noises noticed. What is goin on here? Any ideas appreciated, Thanks.
