been driving truck pass 3 days. since weather been nice no problems,took off from intersection .truck pop back through intake not loud .I let off quick truck drove normal for about15 sec .then started going lean .now hard to start when it does start idles 18.0 afr .if you try to ease into throttle cuts off ,if throttle fast off idles it rev normal .have good fuel pressure not skipping .change front 02 sensors they were brown dust looking .only did out the ordinary was got gas from a new spot .I added my race gas concentrate as always .any body with ideas please

 

might of busted the intake open or youre dealing with a hurt motor

 

check your plugs?

 

have check intake . I was not even running 40 mph .I doubt motor could be hurt.

 

speed has no issue with a motor popping but all of sudden lean... ive saw stock intake blown apart

you stated you checked intake, did you remove the intake and inspected it?

 

changed my 2 bar sensor problem gone.

 

oh ****. really? damn. ive never heard of a map going bad. thats good though it was cheap lol

 

odd a map sensor all sudden goes bad
