First, Although I don't know anyone here yet, I want to thank everyone who put together and contributes to this forum--these places are the about the best information resource any owner can have. Hopefully, I will eventually know enough that I can contribute.

A little background: I bought my '85 Dodge D50 this afternoon. It supposedly has only 136k miles. It's 4wd with the 2.6 liter engine and a 5 speed. I just needed a little truck to use while I am restoring my '71 240z. It's completely stock, beige in color, has almost no rust (amazing) and runs well, although that brings me to my question--the truck was idling fine (under 1000) until, on the way home from buying it, I bought and installed a new air cleaner, since the old aircleaner was incredibly old and dirty. Immediately after install, the idle speed shot up to maybe over 2000 rpm and the engine would "diesel" for about 6 seconds when shut off. This is occurring with the engine fully warmed up.

I googled some info off the web and what I found was is I should use the SAS-2 screw to adjust the idle speed, but the info I found seemed incomplete and maybe not for my D50.

Apologies if the answer to this issue has already been put on this forum--I did not find it.

Thanks in advance,

Matthew
