Help me with my 88 suburban
I just bought this truck. It's a 350. It was driving fine, and now it's started to hesitate when I step on it to much. If I accelerate slowly enough, it works fine, but if I step on it it'll bog down, and I can even hear a little knock, but if I step on it harder it'll accelerate through all that and gain speed. I changed the air and fuel filters, and just dropped some fuel injector cleaner in the tank. It's running a whole lot better but it's still doing the same thing! I just moved out to LA and I'm trying to avoid being ripped off by some mechanic out here. Anybody have any similar experience that could offer help? Thanks in advance

I got a 99 surb and it was doing the same thing. I did the fuel filter change and then put a can of seafoam in the tank, after about 150 miles it cleaned up and runs great now.

If you have not found a fix yet try unhooking the EGR valve, if this curse the hesitation then replace the EGR valve.
