Sorry for this long long post but ive been through 100+ pages trying to help me.
I bought this 1987 Chevy suburban R10 RWD TBI (even though it has a logo thing on the truck that says "fuel injection" a year ago. for a little backstory, this truck sat under a awning on a property from 1994 to 2016 when i bought it. before i even turned it over to test drive it i did a change on all the fluids in the truck and allowed time to sit in the engine. it turned right over after that long! so i bought it.
i took it home and realized i was driving with a locked caliper and almost caught the tire area on fire, i replaced EVERYTHING involved with the brakes. the next thing i did was cut the catalytic converter off because of its age and it was full of crap and clogged. i installed a cherry bomb where the CAT was and just went straight piped out the back . it increased the power to the truck immensely. it ran amazing for a few days but then i noticed a loss of power when i would press the gas upon accelerating it would seem to take a lot of pressure on the pedal to accelerate. now its been three weeks and the acceleration is ghastly, when i'm already at speed, if i try to accelerate(even slowly) it seems to actually slow the truck down until i press it almost to the floor and it kicks into a higher rpm and takes off but sounds like its gonna hurt the truck(it acts like i'm pulling a huge trailer with another suburban on it lol) and if i let off the pedal at that point it goes back to losing power.
I have replaced : cap, rotor, calipers, brake booster, master cylinder, wires, plugs, air filter, pcv valve, belts, battery and maybe a few odds and ends.
keep in mind i have learned everything i now about mechanics from having to teach myself how to replace crap on this truck so keep that in mind.
Thanks for anything that helps
