2006 1500 Ram 5.7 Hemi Tach / Faint Backfire MPG

I have a 06 RAM 1500 5.7 Hemi. The Tach has worked off and on since i bought it @ 50,000. yesterday it worked fine. today it is reading slightly more than zero. If you nail the pedal you will see the needle come up. I noted the truck is not getting the MPG 12 / 17 it was when i got it 16 /19. the truck has 89,000. i notice a very faint backfire. I have changed the plugs, and did not affect. I have no lights, or codes that come up on a scanner. i did see a mention of "cleaning the IAC" could the tach, and drivability issue be related?

Try spraying water while it's running on the engine, plugs, wiring from a spray bottle to see if you can locate where it might be acting up from!

Go here and it will tell you how to get your codes. Actually on an 06 you can just turn the ignition on and off 3 times (dont crank the engine) and the codes will show up on your odometer. But here are all the codes. PS you can get a manual on pdftown.com for free too.

SOURCE: I have a 2001 Dodge Ram 3500 4X4, w/5 spd tranny.

tach is most likely a cam sensor, hvac could be a bad vacuum problem (bad hose ) the electrical (dash stuff) I would start looking for a loose or bad ground wire or dirty battery terminals
