Ok so Ive searched everywhere and done everything known to man BUT solve my problem with this.
Basically I bought it Jeep and it was running rough...would blow some black smoke when heavy in the throttle.
Threw a p0171 - System Too Lean
Replaced the first o2 sensor and that code went away
Then a week later the light comes back on and it starts running rough again..no smoke now but it trys to idle very low around 400-500 rpm and sputters at idle like a tractor. runs fine off idle and through the rest of the RPM range though.
I get these codes now
p0300
p0301
p0303
I was able to swap injectors this weekend. Just swapped one and two beings it was throwing a code for misfire on 1 and 3. Didnt change a thing so it still comes up Misfire on 1 and 3. So that rules out the injectors, plugs, wires, cap, rotor, pick up coil. Not sure what else to check other than swap out with another ECM.
Got another code on start up this morning P0141 Oxy Sens Heater Circ (bank1, Sens2)
Any ideas guys?
