code 41 on ford ranger?
everything was checked and double checked,everything is pretty new and clean, no leaks of any kind, check engine lite comes on 15 min after driving, when u shut the truck off and restart it, its off ,till the next 15 min , no problem running what so ever, the only thing isnt quite new is the oxygen sensor,7 yrs old, drive it 6 months out of the year and only put few thousand miles on it. my antilock brake lite is on,been on for 3 years and was perfect.the test was koeo test.
