GMC Sierra 3500, Truck
#29 of 36 1986 Chevrolet truck, 350 engine - Acceleration Dead Spot
Jun 09, 2009 (9:02 am)
1986 Chevrolet truck, 350 engine, ¾ ton, 4 speed manual – bought the truck recently, after replacing carburetor, distributor, cap, rotor, wires, vacuum hoses, radiator, thermostat, also pulled emission controls off. I hauled a 27’ 5th wheel to the lake (80 miles), no problems and ran and pulled good, on the way back it developed a dead spot in acceleration between acceleration and de-acceleration. The exhaust smells gaseous. Checked all the vacuum hoses, connections, etc., adjusted timing. What now?

I just bought this truck,it has 78,000 miles on it and I thought it was a good deal, 350 engine,auto. I have several issues:
Heater: I can't get the heat off the floor. It won't blow on the mid range dash vents or on defrost. I have removed and taken apart all three actuators and they all seem to work. I have pulled apart as much of the dash as I can to get to the vents thinking they might be jammed or rusted shut. I am unable to get close enough to manually open them. I noticed the radio controls for speaker settings are sketchy and wondered if it isn't the push button controls for the heater system that are bad.
4 wheel drive went out on me Christmas morning, stranding me in the sand for a couple of hours.It went into 4 high, the fell out into 2 wheel only. I have the stick on the floor shifter system, light doesn't go on. I had to be pulled out. I have read about the "shift actuator" in other posts. Maybe that's it, I don't know. I figure with the low miles and barley used 4 wheel drive by previous owner, it can't be anything big like the transfer case. I can't figure out why they don't make these actuators fail in 4x4 only so you don't get stranded in 2 wheel drive..
Radiator leaks. I can handle that though. Kind of disappointed as I am used to old Jeep CJ's with manual hubs and go anywhere attidtude.
Body is in great shape and it is a looker. I want to get it up to speed mechanically and drive it lightly. I appreciate any help.

I think my power steering cooler is leaking. Anybody know how to get to it? It is attached to the radiator on the side. I can see it though the grill. Maybe I have to remove the grill to get at it?

Just bought 1975 K20, 350eng, Holley Carb and others, it starts right up, idles great, put it in drive or reverse no problems... press on the accelerator and it wants to die, for 1 i was told the Holley carb is probably in need of some adjusting, but they can be a pain in the neck, and frankly i have no idea what i'm doing, haven't checked the timing yet but that'll be next, please someone give me some tips, i'm an automotive idiot
