P1684, P0622, P0403, P0134. These are the codes that I got from my scanner, what do they mean? Thank you


My guess is you may have wired something up wrong, or installed a faulty part. Either that or forgot to plug something back in while you were putting it back together. In other words replacing a battery and alternator shouldn't cause the oxygen sensor to go bad. So my suggestion is to check all plugs and wires to make absolutely certain everything is put back together correctly before you sink more money into fixing what's not broken. Haynes repair manuals list all the engine fault codes so for everyone else reading this, if you get codes check your manual or head to the library to look it up in theirs.

I need to know what the diagnostic code PO1448 means? thank you


Well it's not a p0 code which indicates a generic trouble code, this is a code p1448 which is a manufacturers specific code, and your stands for a bad manufacturer controlled auxiliary emissions controlled component. Try checking your charcoal canister which filters fuel vapors from your gas tank, there is an evap vent control valve which can get stuck in position. You can replace that valve or try cleaning it with some carb cleaner and then using a small screwdriver to free the plunger up. Your check engine light will go off after a couple drive cycles without a fault or you can reset it iwth a code scanner.

Repair maual for 1997 1500 Z71 pickup with 350 vortex and 4x4


I have a 1997 chevy 1500 350 4x4. My problem is that I can not get my headlights to work. I have checked the fuses inside the truck and under the hood. They are all good. My side markers work, my tail lights works, and even my day time running lights work. The only thing that doesnt work is the headlights. If I turn my head lights on my day time running lights turn off. Does any one have an idea of what could be causing this.
