- '99 XLT Explorer
'99 Ford Explorer, Ran like a typical Explorer with Intake Manifold Gasket problems,
Error Codes: P0171, P0174, P0135, and Cylinders 1, 2 and 3 misfiring.
Changed Intake Manifold gaskets, 171 and 174 came back on, ran a circuit test, cleaned MAF sensor and changed O2 sensor (passenger side, behind front tire.)
Now it runs worse than before, every 5-10 miles it begins to stutter and spit, and when I step on the gas, it does nothing. Then it snaps out of it and runs fine for another 5-10mi.
Where does my issue lie now? I still have Error Codes 171 and 174.
What should I try next?
