Ok well i got the check engine light running too lean in both banks, 2001 ranger edge 4.0 4x4. I noticed tonite after i got home from work roughly 20 mile drive i turned the truck off and i heard a "farting noise" Could that be just a vaccum leak i did notice a little air coming out of the throttle body spacer the new gasket is on the way. Any ideas? Thanks all!

 

any input please!!

 

i think its probaly the compressor just making noises. mine does it when i turn the ac or heat off.

 

not to long ago i had the "both banks, too lean" and it sucked. there was a cut in the elbow piece or w/e thats part of the intake manifold. blew alot of money just finding the leak

 

well i did the pcv valve and the line it runs alot better but i know i still have an air leak in the throttle body, i'll let you all know thanks for the imput the new gasket/ O ring will be in tuesday. The sound is coming from the engine compartment its weird i'll pull in shut off the radio and heat wait a minute then shut it off it makes the fart lol its funny its hard to describe the sound other than that. Thanks all again!

 

mine does that too, what did you end up doing to solve the problem?

 

just use some rtv or somethin like that, it should work fine. and its a cheap fix.
