Engine bogs down and stutters under hard acceleration
I have a 1994 chevy suburban (didnt give that year option when choosing for post) with the 5.7L gas engine. She idles fine, revs fine in park, but when I go to drive, if I accelerate hard she bogs n stutters. If I'm in 4th gear and try to accelerate, same thing. I can only accelerate very slowly once in fourth gear. Engine bogs down, trans doesn't seem to even try to downshift to help accelerate. Trans was rebuilt a couple years ago, and I'm trying to figure out what is broken so I can fix it! Distributor is less than one year old. Am going to replace fuel filter. Don't think that's the problem but I'm doing it anyways. My father checked it out and said it smells like its running rich. Could this be causing this? Should I replace o2 sensors?
