TBI Smell
My 87 has a 350 TBI in it and it seems to be running to rich. When I get onto the highway and i get on the throttle some smoke comes out of my exhausts and it when i am at a stop light or just idling it has a smell of to much fuel or something. It gets about 8 miles a gallon when i am staying off the throttle and about 6 when i am on it all the time. I did a full tune up on it last year and this year I installed a throttle body spacer. The truck runs great but it has been smoking and getting that MPG's for a couple of years.
