i have a 2000 ranger w a 4.0 and recently developed a rough idle. first code was a cylinder#4 misfire. after plugs and wires it was gone until engine warmed up.since then it has developed a rougher idle and upon loading it will loosen fillings.it since has coded misfire on 4 and 6 cylinder #s along with a left bank up stream o2 sensor and a code 1151 manufacture fuel air mixture?in the last two days i have replaced #4 and 6 injectors for the misfire,plugs and wires(quadruple) checked the wire locations. i have replaced the upstream bank 2 o2 sensor again along w the the thermostat and the temp sensor as i then coded a highoutput temp code this is in addition to the intake gasket replaced as well.it drinks gas like no tomorrow and since my final clearing of codes i have not gotten another code but it still runs like garbage. cylinder pressure meet book specs and fuel pressure is 62 before starting and 68 while running. im at whits end here and have a new coil pack on the seat that i dont want to install because i reallydont think thats it being the misfires are on seperate banks, please if anyone has a suggestion i would greatly appreciate it. thanks guys!
