If your 1991 Econoline won't idle or shift properly, it could be due to several issues. Common causes include a malfunctioning idle air control valve, vacuum leaks, or problems with the throttle position sensor. For shifting issues, check the Transmission Fluid level and condition, as well as the transmission filter. It's advisable to perform a diagnostic check to pinpoint the exact issue.

You may have to clean or replace you Idle Air Control (IAC) valve. Mine did the same thing, but after I cleaned it, I realized that it idled too low, so now I have to replace. Be forwarned... you will most likely have to order the part (it cost about $43.00) or you can get one from a junkyard if you trust that. Hope this helps.
