rough idle in all gears, park drive, ect.
i am having trouble with my 94 ford tempo 2.3l 4cyl. its just started a couple days ago and idk what its deal is. when i start the car it idles normal but runs really rough. i am lucky to get it into gear without it dying. i have been mass air flow and idle air control, o2 sensor or sensors and a load of other stuff but the guys i was talking to arent the brightest bunch of mechanics you will ever meet. im just trying to get another opinion before i go buy a 75 or 80 dollar sensor that it might not need. just put new spark plugs in it. has compression and fuel pressure and has a half tank of gas. idk what to do. any help would be appreciated. thanks have a good day.
