oh MASTER SCOTTY !

I HAVE A CODE P0171 "SYSTEM TO LEAN BANK 1" DOES THAT 1 CYL IS BAD? WHERE IS THE MAF LOCATED IN THE 03 HONDA CRV AT if any or is the map the maf ?
I FOUND THE MAP AND INTAKE AIR TEMP SENSOR AND CLEAN THEM WITH MAS CLEANER, CAN YOU HELP ME. WHILE ENGINE IS RUNNING
I PULLED THE PLUG ON THE MAP THE
ENGINE CUT OUT A LITTLE HOWEVER ENG STILL RUNS does that indicate the map is BAD or the I.A.T.S is bad too?

your engine is running too lean, it only has one bank being an inline 4 cylinder engine. It has nothing too with #1 cylinder being bad. AND, Unplugging stuff is not a good test anymore due to computer software back up programs. You honda does not use a maf only a map. More often your problem is a vacuum leak https://www.youtube.com/watch?v=zMok2y05jNE

Thks oh master scotty they told me when upped map harrness and put back while running it wipe out the codes and the dealer said let the suv have a fault. since it is wiped out code can they reload the software back in also their was no leak
They told me it is to rich
Lean means more air than fuel ? Or vise versa. I also
For purises i use maf cleaner to clean map and iat and see if that cleared the ck lite. Thks oh mighty master.

If you wipe out the codes on 03 crv honda can they reload the software at dealership or your out of luck or when a fault is found it will reinstate it
Plus when take for smog in calif will the car pass or what. Thks oh mighty master.
