Being the cautious fellow that I am, I started this process at what could be looked at as the "beginning" - I dismantled the intake from the air cleaner to the fuel injector/throttle body thing. In taking off that black metal tube thing with the large vacuum line coming off of it, I notice that is was kind of dirty so I threw it into the kitchen sink (literally) and washed it thoroughly. Then I stuck my head into the throttle body (figuratively) and noticed that the butterfly valve was a little grimey, so I sprayed Berrymans Carb/Throttle body cleaner ($4 at Autozone) into it and threw a toothbrush in there as well and scrubbed around inside gently as to not break off any internal stuff and the toothbrush came out black at pitch. I then repeated the process a few times, reassembled, fired it up and after the Berrymans caused a little combustion of it's own, the idle was smooth as a babies ass. I also have replaced the lion's share of vacuum lines (one at a time of course) and plan on replacing the rest to ensure the proper amount of vaccum. I will time it also however - just to make sure things are tip-top.

Off topic, this website is a gold mine of information that just doesn't exist to a person who doesn't know about these trucks, thanks a million and if you are ever in the San Antonio area - I owe you a beer.

How do I find the timing mark? I messed around with rotating the distributer cap, now I have that lovely "chatter" when the engine is under load going up a hill. The truck is a 92 2wd max... anyhoo, I am going to try to turn it back the other way (not that I moved it too much in the first place).

as usual, all assistance is appreciated.
