MAF mod question???
I did the MAF mod to a spare maf housing that I had. It is for a 99 3.0 FFV ranger.
My question is:
When the modded housing is in, it runs fine. But then starts to ping when the engine is under a heavy load and the CEL light comes on and gives a code P0174 SYSTEM TOO LEAN (BANK 2).
When the normal housing is in, I don't get a CEL light and no pinging under a heavy load.
I did the mod as described at Rogue performance's web site.
The link is Rogue Performance MAF Mod
Any one have an idea of why this happens????????????
