    surging?

    I guess that's what you'd call it. My Bronco (302), it'll run faster than it should every one in awhile. I haven't noticed it when it's sittin there idling, but when driving it does. I've let it cruise by itself and it'll go 30 without touchin the gas...it's a lil slow gettin there, but it will. I jus did plugs and wires and cap, rotor and coil. I replaced the IAC valve thinkin' that was my problem. I let it sit over night with the battery unhooked (neg cable, does it matter which one?). It still does it. I'm not gettin' a check engine light now tho.

      throttle position sensor, perhaps? Can't hurt to check for codes before you start throwing parts at it.

        I vote for vacuum leak. It makes for a high idle and wierd surging. Check the soup can, they rot out.

            No CB yet. I didn't check for code cause I had no light on. Now I do every once in awhile, the check engine light. I went to AZ to see if they could check but the kid didn't even know there was anything but OBDII, he was tryin to find eecIV on the computer like it was a part

            I broke 2 plastic vac lines when I did my tuneup but I fixed those and it was fine....for awhile. I hate this shit...fix one thing then it's another...

                    The stupid thing about EECIV is that it will set codes but not turn the check engine light on except for a second to let you know that a code has been set. If the light is on constantly, that's when something is really wrong (i.e. sensor unhooked)

                      Is the a/c on? Some of these have weird controls that enable and disable the a/c clutch depending on engine speed.

                        Yea I know shit wears out. Just venting cause it all happens together. No I didn't have the a/c on when it was doin that. and the can seems fine, altho it was really hot after I ran it awhile.

                        Now It hasn't done the surging in a couple days. I routed the wires a lil different, maybe that helped. But now I'll be doin front wheel bearings tomorrow. Pass side almost seized up on me last night.
