99 ford escort zx2 cleaned maf sensor, still idleing rough, already changed o2 sensors, is there another sensor i should check?

Listen up! here is the solution I have had to replace two of them on two engines and they are always missed diagnosed by dealers because the techs these days dont understand the basics of a 4 cycle gasoline engine and they use scanners to find problems, instead of checking for fuel, spark, compression, and vaccum.
On the under side of the intake manifold (accessisble only from the underside of the car) you will find a 3/8 inch vaccum line that goes all the way around the engine to the pcv valve on the front of the engine just below the valve cover. This hose rot's right at the intake manifold nipple. this happens because of the heat coming off the exhaust manifold that is very close. So becareful when inspecting. Its avalible from Ford for aproximatly $20.00. have fun and tell the dealer to shuv it.

Try disconnedting the negative battery cable, that should reset your ECU see if that works
