That was the code I pulled off my 1998 Accord with my OBD II scanner. I've noticed it hasnt been running quite right. What should I do to correct this guys? Clogged injector maybe?

system fuel too lean bank 1

BTW car is a 1998 Accord LX 4cyl. Auto...

 

More specifically...
P0171
System Too lean (Bank 1)
P0170
Fuel Trim Malfunction (Bank 1) (Pending)

Those are the readings I got

 

If it were a german car (I know it's not), then I would say the Mass Airflow Sensor. In your case, I would look for a vacuum leak at the manifold, or one of the hoses going to it. Something has to meter the amount of air going into the manifold. That fault indicates there is air entering the intake AFTER that sensor. Good luck though.

 

I am not positive this is my problem, but seems to be...

What do you guys think?

 

I don't see why not....seems simple enough that you can do it yourself...get the parts from honda and find out.

 

Guys I replaced the Fuel Pressure Regulator, and now theirs a louder sound I can hear, it almosts sounds like its behing the motor, its rather audible and annoying in the car(almost a tick/knock) noise. Still seems to be running funny, almost sounds like an air leak somewhere near the Throttle body, is it possible the seal or whatever between the TB and the intake has a leak?

Anyone have any idea? If I hit the gas real quick and let go, the idle drops so low it almost dies then it picks up...Only sometimes though(doesnt do it every time)

 

Didnt hook the fuel presure regulator up go back double check you lines. Check, Double Check, Triple Check.

 

I hooked it up identically to the way those Honda Papers showed, it is different from their origional configuration, because supposed with the origional configuration, moisture gets into the pressure regualtor. Should I hook up the hoses in their origional layout maybe?

 

Hey could it maybe be the intake manifold gasket?

 

Did you ever get this problem figured out? I am having the exact same issue.
