HELP !!!! 2003 Ranger 3.0 (not flex fuel eng). 230K Have had a p068 code and cant seem to locate it. I know what sensors kick this code and pretty much why. I have been through ALL the vacuum lines (EVAP tank to front bumper ). Replaced intake gaskets. evap purge valve. plugs .wires . coil. MAF . TPS. PCV. various hoses and gromets. even the gas cap ! I did have a Catalytic converter stopped up bad. I opened it up (truck only has 5 total) a couple of months ago. now truck runs VERY RICH, rolls coal like the kids with diesels .Using fuel like its .50 a gal. I read somewhere about "Volumetric Efficiency ". Thats a little above my paygrade. Anyone have a similar problem ? Any HELP would be greatly appreciated

 

UPDATE .......Turns out that after a month of 'hunting and pecking'.. The MAF sensor i replaced 3 months ago was a BAD SENSOR . Bought online , don't remember where, but it was NEW and CHEAP. So buyer beware. Some NEW products are not always good. It's worth the time to check the voltage to make sure its good. Hope this helps somebody.. good luck.. Ranger on fellas!!

 

Thanks for the update and one more "beware of new parts" from 3rd party sellers

 

Probably made in China.

 

What was the brand of the MAF sensor ?

 

Lol. Yeah, like everything else. "Made in China". And. ASSEMBLED IN THE USA.
