hi every one my rx will start and idle fine you can rev it up but when you go past 1/2 of throttle it hesitates really bad and i found a big hose that i remember i think came off the main cat i stuck my finger in it and reved it up and it has vacuum when the Rs are coming back down

i remember swapping the bad afm for one out of a nissan could this be my problem



and no i didnt sell it yet

 

a nissan AFM. LOL. you might to try an rx7 AFM that is probably the problem

 

If that isn't the problem, try checking for vacuum leaks.

 

?
