horrible idling problem
ok heres whats up... i changed my timing like a week ago.. shortly after.. next day... bout 75miles later... this week surge happens when i let to car idle at a stop, or sit in neutral, its gotten worse and worse... long surges were te rpms will shoot up and stay there for a while... or quick fluctuation in rpms... its even starting to drop so low after reving up that it will die... it doesnt do this when i and giving it gas... and it does surge a lil bit when i am good but not giving it gas... like down a hill or sumthan... so i dont hey just move you timing bak... well actually when i put it bak to 10 it almost seemed worse... so i moved it bak up a lil at 12 it seems to be a lil better... so i left it there... rite now its apart im puttin Mac lt headers and a prochamber on as well as pulleys.... some of the pulleys were a lil bad.. but not majorly bad.. but i think i will be replacing htem newayz... there 11 years old with 43k on then... they came with the car... also i put some seafoam and lucas injector cleaner in shortly after this surge started happening thinking it would clean things up... which i htink it did.. but it didnt fix the problem... neone ahve ne ideas

RE: horrible idling problem
you can get a ford obd1 code reader and your local parts store. and yes there are codes stored if the CEL is on. btw ford also made it to where your car may still throw codes even if your CEL isn't on.

RE: horrible idling problem
replace your IAC valve, they cost like $30
they like to act up as the weather starts to cool and you get condensation in them.
IAC valve regulates how much air by-passes the TB at idle, hence controlling idle.
when they start going out they stick and wont idle right.

RE: horrible idling problem
I was quoted 60 bucks at Advance Auto for one, Try removing it and cleaning it with some carbcleaner before buying a new one. My old vacuum leak was also accompanied by a surging idle....something you might want to look for before spending any $$$.
