Well, its an A833OD 4spd, not an auto, so the kickdown would be ruled out. Pretty much doesn't matter what speed. It occurs in every gear, but most noticable in OD4th. Hmmm, that's right, vacuum gauge! Should have thought of that first. Doh!! I'll try that and see where it leads me.

Did you do the swaps all at once, or one at a time? What worked first?

You are best off only changing one thing at a time. This way you will always know "what made it better" or can always easily change things back to the way they were if problems become worse.

Another thought i had on this, albeit unlikely, is perhaps your coil is weak and not providing a hot enough spark at higher rpms. If you have a known good coil to try out i would do that next.

Have you made any determination on the cat yet?

No determination on the cat yet. As a matter of fact it's pouring rain out off and on today. I'll probably check it out this weekend. Keep you all posted.

Oh, and to Justin's response, I was looking to see if his was all leanburn, cat, or a combination there of.

As far as coil, I hadn't even thought of that. It is original, only has 70k on it, but is 20 years old. Maybe.....hmmm, I'll check that out too.
Gotta break out the tools this weekend I think.

Well.......the cat is fine. Checked using a vacuum gauge. 22" Hg at idle, as a matter of fact good vacuum across the board. The gauge held steady and didn't drop. Also, the vapor out the pipe turned out to be just that.....water vapor. The smell seems to be more on the HC side now, might be slightly rich at idle. So now I'm thinking the bog is being caused by the Leanburn system. I think the best thing I can do at this point is to convert it with the MP electronic ignition conversion kit. When doing this does the carb need to be swapped too? It's not a feedback type carb, but would it be jetted too lean? Its a Holley 2280, not the original to the truck, but it is a Holley Reman carb. So I'm not sure if it's for the application or not. I thought in '83 they only used the Carter BBD, but I could be wrong. Can anybody shed some light?

Nope, did it all at separate times

First off i cut the CAT out, it made the engine run alittle better any you could tell it made a little difference, the next step was to swapp the lean-burn out, this pretty much did it all, set the timing at 12* advanced and it was good, did the muffler out later because my old one was done, other mods consisted of using a clutch fan, and hooking up the EGR (powergoes down, milage goes up)

If your throttle solenoid is grounded past idle your distributer won't advance. Have you checked your timing with a timing light? Super 6 made a good point about a weak coil. Some body also may have installed the wrong coil. My 85 uses one with an internal resistor an no ballast resistor.
I had problems on my truck with low coil voltage. It was a combination of a weak alternator (new from Autozone) and poor grounding. Compare your Battery voltage with coil voltage with the engine running and the lights and all electrical accessories on. I think some of these trucks had a problem with the amp gauge causing a lot of resistance in the system. I noticed the one on my truck was deactivated.
I built a backup ignition system for my truck using a vacuum advance distributor and GM HEI ignition module. It took 10 minutes to install. For my emissions test I will re-install the old distributor along with the catalytic converter and air pump. Good luck !
D150

Throttle solenoid? Ummm, mine doesn't have one. The more I'm checking this truck out, the more I'm finding by-passed or removed. I think its also missing the air charge temp sensor and the egr solenoid. I think I've gotta pay a visit to the junk yard soon and find a fairly complete /6 leanburn truck, do some studying. Maybe after replacing these items the truck will run the way its supposed to.

OK the Ram is finally fixed! And you know how stupid a thing it was? Air charge temp sensor was missing! I replaced it (cost all of $15) and now the bog is gone. Not a real powerhouse by anymeans but drivability is back. The computer must have been in "limp-home" mode for years! Now it sees what it needs to see and runs decent. Thanks for everyone's input on the subject.

Glad its fixed

Sounds like a route for me. But I think my problem might actually be slightly more extensive. After running my '83 D150 about 75mph for 15 min and stopping at a fast food restaurant, I noticed smoke coming up around the cab. When I parked, I found the cat glowing bright red. I have a slight oil leak so I assume most of the smoke was from the oil being burned on the cat. The muffler man said I was dumping too much fuel into the exhaust causing this. The carb was recently rebuilt. I would hope the shop did it right.
Since I live in a county that requires the sniffer, I'm not sure if I can legally replace the lean burn ignition.
