I have a 1996 civic hx coupe...and yes I am sorry to say but it is bone stock. I have a CEL on, and although this may seem common. Here comes the stumper part. I jumpered out the computer to get the CEL to flash the error code and got a 48 (lean air fuel sensor). No one at the shops around here knows what that is. I put a snap-on obd II reader on it and got an error code (Air metering). Only problem I don't have a map sensor on my car. The car is also hesitating very badly and stumbling along. I performed a vacuum test with no results, everything is ok there. I am hearing that it is the above o2 sensor not my after, Any help here tech guys would BE AWESOME!!!!!!!!!!! please help I'm desperate.

 

You have a MAP sensor you don't have a MAF sensor.

 

ok, sorry i'm just learning the engine stuff.

 

Change MAP sensor

i took it to the honda dealer, and they say my engine is bone stock and still no map sensor, they say its the upper o2 sensor, and I checked everywhere b/c the price they told me was $452.96.... I checked all over the net, and for a before cat. converter five wire manual o2 sensor they run between $400.00-$424.00. I know i see it for myself, but dang i still feel like i'm getting rammed here. thx for the help guys.

You do have a MAP sensor. It's located on the top of your throttle body:

Also, there is no HX coupe, only hatch... h:

 

Theres an HX coupe, and no hatch h: The VX is only a hatch h: The MAP sensor is also rivoted on the throttle body.
