Problem Solving

Can anyone tell me how the KA will run if the MAFS is not working correctly? Also, what about an oxygen sensor. I've been trying to sort out this problem with my engine, and I don't know what to do now. What about if the fuel pump isn't pumping right? My acceleration is horrible. I'll have the pedal to the floor, and its accelerating like a damn honda.

Why don't you just take off your MAF and clean it with some CARB cleaner and replace the O2 to find out what's wrong. That would cost you all of $30 or somewhere around there.

Is it accelerating like an Integra Type R cuz that would be pretty good. Or how about like an S2000 or an NSX. That would be even better.

anyone do this? is the MAFS something that can get dirty and not work properly?

ive found my car to be fussy like that everyonce in a while it will be very sluggish. Do a usual tune-up, fuel filter, clean / gap / replace plugs, inspect wires... check your mafs connection, although if i recall the car wont even run at all if its not plugged in

Well, I am seriously starting to think it is my fuel pump. Becuase sometimes now it has a hard time cranking. I've spent over $300 lately trying to work this thing out. I've had the engine scanned, and it came back injectors. I replaced those, and helped a little, but didn't fix it. I've replace the air filter, fuel filter, spark plugs, spark plug wires, dist. cap, and dist. rotor.

The MAFS sensor is definitely something that can get dirty and just screw up the way your car runs. All those sensors are a mystery to me, but cleaning them off or checking them out once in a while definitely makes a difference. Definitely give it a shot.

Good luck,

T in to the fuel rail or wherever you check fuel pressure and check it. I dont know stock FP specs but you could find it.
