Hello im new to this site so im trying to get used to it but I always found answers on here so I thought it would be a good Idea to join so i could ask my own. I have an 88 dodge ramcharger with the 360. It starts and runs fine through the first 3 gears but when it shifts to 4th sometimes it really bogs out and has no acceleration at all. But does fine when I pin it and accelerate up to highway speeds. What could be causing this? It cant be a clogged cat because I already hacked that off I would like to get this problem resolved because when I'm driving through town at around 35 sometimes it bogs out and when I try to pin it it will stall. I also have tried running a bottle seafoam through the gas tank.
