92 explorer 4.0 rough idle/stall when cold

my 92 explorer runs fine when warm, but on startup...even if it has just sat for a few min it idles rough and stalls...it starts right back up, and does it again...then the rpm flutters between 6-900 until fully warm, even then i get a small rpm pulse.....the car is new to me...any ideas?

I would start with some basic diagnostics: test fuel pressure (see sticky in Under the Hood), check for gasoline in the vacuum line to the FPR, and pull codes (see stickies in EEC-IV forum). Check for vacuum leaks. Look for anything disconnected/unplugged under the hood.

For #3, and sometimes #2, I reach through the wheel well and get at the plugs from underneath.

hey there thanks for the info....seens to ide far better now with new plug wires and a good cleaning of the mas & tcm...plugs are next.....and another question, ....the fuel filter...is it on the frame rail? I'm getting an occasional dead spot for a second and am assuming it is the filter since it has never been changed, i'm thinking this is causing the occasional stall when at idle. so, wires, filters, plugs...any other tune up tips for these rigs?
