I got a first Gen B16 in my REX. Sometimes it'll hesitate before 3000PRM, then pick up after. What do you think it is?...THX in advance

 

MAF sensor might be going out... I know when my MAF sensor went out.. i couldnt even get it up over 3k rpms..

 

codes?

 

how did you wire the two Oxygen sensors? you may have them wired reverse

 

or if its really noticeable it may be the TPS, did you take it off or anything?

 

no its wired cool it wasnt doing this before it hapened after i changed the alternator and no codes

 

bump

huh?

Sounds like an o2 sensor to me.

 

ya thats what i was thinkng. Im gomma swap out both. I think its o2 sensor because im gettin a lil less MPG...

 

I dont think its the o2 sensors i think it might be the map because it wont do it at any other RPM i remember my friends car was hesitating through all RPMs until VTEC mine no itll only hesitate till 3K..

It really depends on how badly it's reading. I've had both senarios.

 

ya i guess i gotta bust out the DVOM...
