[crock1990]

Ok, im new and happy to be here, o I just bought myfirst ram 50,sf4x4, 2.6. The truck runs and drives great, but has no power on hills, its almoat like the two barrel isnt working right, any answers or help would be great

Welcome to the site,you will get answers later tonight from the old heads ! I have fuel injection, so I'm no help

[crock1990]

Lol, I think the secondary throttle actuator is bad but im not 100% sure, all I,know is when its running I can only see fuel onone barrell,

[92bluemax]

Crack the throttle and see if the secondary opens

[crock1990]

Ive done tgat, with the truck off or on, it only opens if I do it manually at the tgrottle actuator

[crock1990]

But yes I can get the secondary throttle plate open

What size tire are you using. Many times people put on a bigger tire just to loose power. Check tomming and replace the O2 sensor to start with. Also look for vacuum leeks. But the tire is a BIG factor.

[crock1990]

Factory size, I just replaced the o2, & ive check, listend, and sprayed fir vaccume leaks

[crock1990]

Ive also messed with timing, and the cat , I tested it and it checks out good

[crock1990]

New plugs, wires, cap, all filters

[crock1990]

Ok, so I just put a vaccume pump on the secondary throttle actuator with the engine off and it would not hold any vaccume presure

[crock1990]

Any comments or help would be awesome

[crock1990]

Thank ya, and that was actually the post that got me on here, abd the one that helped me

[ikeepzitclean]

ur welcome bro. hope that helped.. did u get it figured out?

[crock1990]

Ok, so I replaced the secondary actuator, got both barrels workin, but now when I hammer down it boggs?

[92bluemax]

Is the choke sticking?

[pennyman1]

check the accelerator pump to see if its working - it should shoot out a shot of fuel into the secondary when the throttle is rotated fully.

[crock1990]

How do I check? The vaccume line that was going to it has no vaccumr so I put a constant one off of somewhere on the carb and the secinday opens and works jus feels likes its overloading with fuel at high rpms

[92bluemax]

Look in the secondary barrell and turn the throttle cable by hand until it opens while looking in

[crock1990]

180000 on motor, could it be a worn cam lobe?

[crock1990]

With engine off the secondary dont open unless I do it manually, how do I check the choke and accel pump?

[92bluemax]

gotta have it running when you check it

[crock1990]

ok, so start it, rev up untill secondary opens, look in and see if I can see a shot of fuel?]

[pennyman1]

x2 on that the pump is actuated with an arm mechanically linked to the secondary on the carb.
