i pulled about 4 more codes other than these ones but thats cuz i didnt do the WOT test.
my main concern are these 3 :
91 and 41 are for O2 sensors always reading lean and will not switch.
81 are for idle air control (IAC) circuit failure.
i just swapped my IAC 3 weeks ago but it wasnt a ford brand part. now driving is fine but when the clutch goes in RPM's kick up to 2200 and hold for about 10 secs then drops slowly to 1500 then eventually 800-1000.
its getting on my nerves and i cant find any vacuum leaks and the TPS is new also.
