sooo ive beent trying to figure out this idle issue with my car and still havent came up with anything...and now the car is having this issue...if slowly rev the motor it goes all the way up to rev limiter...if you got WOT it stops at 3500-4000rpms and seriously sounds like a 2 step under water and just bogs baaaaad!! what could it be?
seriously...dont anyone say anything about coilpacks or injectors...cause really...theres NO PROBLEM there..ive replaced them more than 6 times with new ones in hopes of finding my idle issue!! no problem there
there could be several things wrong. MAF, fuel filter, fuel pump may be acting up, or your ECM going bad. or if you have a chip the chip could be loose. hope its not the ecm cause that is expensive but they can cause some wierd problems. or haha mine would do that when i had water in my fuel. have you tried a bottel of HEAT
yeah I would to easy things first. try cleanign you MAF with electrical parts cleaner. check your fuel pressure at the rail and compare to factory specs, change fuel filter (if avent already). an pray its not the ECM
brand new injectors,fuel filter and fuel pump are in this car...no tune or anything like that are on the car! ima try cleanin the maf but uhh...could it be the ecm...like maybe thats my problem on why the car doesnt idle right< wish there was a way of knowing
all ford modules have to be programed into a car/truck using the IDS system.
yeah i found that our when i swaped my ecu and i highly recomend just calling a local locksmith to come out and do the programing and not take it to the dealer ship cause they will rape you on charges....also have you tried hooking a volt meter to the coil of the dead cylinder to see if it is even getting power
