Because PA ******* sucks!!!!!! :mad::mad::mad::mad:





Dunno have to look. But the emmision label under the hood says 5.3.
Weird. He may have hit the wrong button or a bug in the software or who knows. Just sucks because the emissions profile for the 4.8 might have lower numbers than that of the 5.3 so your engine may have to be in gooder health to pass :/

Side project this week- finish the Stopsign front skid plate, and mount the factory GM skid plate that protects the oil pan to the vehicle. I don't own any taps- and don't like self tapping screws, so I will have to go to the store and get some stainless bolts and some galvanized nuts for the oil pan skid plate. Looking forward to it though. I know its added mass, but the stop sign doesn't weigh much, and I'll be cutting it to match the profile of the factory plastic one, and the GM OE oil pan plate is aluminum- just thick. I know they aren't suited for serious off roading, but they'll be good enough should I slide off the road at low speed. Next month I'll order the one for the transfer case.

No idea why this says 4.8L on it when I have a 5.3L????? o_Oo_O:confused::confused:

The 4.8 thing is just a drop down menu(they use a similar system here in NC.)
EVAP Systems not ready mean you have recently reset a check engine light, and it hasn't gone through enough cycles/elapsed time.

it's like 75-100 miles or somewhere in there.

I can vouch for this!!

Same here. I grew up in Harrisburg and eventually I was an emission and state inspector. Stupid laws, but there were a few good ones though, like ball joint tests. But I hate PA for many more reasons than the inspections, lol. Moving to Colorado was one of the best things I've done.

If I remember right, those are done with a 12 point socket. Take a picture and post it. I don't have a good shot, this is the best I have.
The ones on the back side of this pin, I’ll get a better pick tomorrow

The obd check for emissions includes that a certain number of and/or specific system monitors show a "ready" state. This includes catalytic efficiency, evap, etc... I bet @Rocket Man is right, and that Range device spoofs something for the AFM. When you remove it, that module shows "not ready". You need to drive it. You won't have any way to know the readiness state without a scanner, but usually 20-30 minutes or 40-50 miles will do it. Vary your driving and get her good and hot.

Quick google for basic info...

Had to do this with my explorer a few years ago
