I want to get as much emissions junk off my truck as i can, but i need to know what i can remove without messing the ECU.
Ive got my Hanes manual that says how to replace some emissions parts, so i can remove some stuff but what about the coffee can, 02 sensors etc. and all the wiring and such?

advise me on how to get my truck free from the EPA handicapps!

 

The coffee can is a vaccuum resevour I believe so you need that. Leave the O2 sensors, your EFI wont work correctly or efficiently without them. If someone makes a replacement pully to replace the air pump then thats one down. Remove the air tube from the air pump and the exhaust and take it out. Hmmm the EGR then. I would find or make a plate to cover the opening on the plentum the EGR attaches to. Im not sure where the tube on the bottom of the EGR valve goes, but you could trace it and see if it can be removed or just unscrew the tube from the EGR and cap it off.

 

going to have ping issues if u remove egr and dont get the eliminator from ffi

 

I know you won't believe me, but the emissions equipment is not handicapping the motor AT ALL.

 

I have no idea why you would want to remove the coffee can and the O2 sensors. I'm with above post they're not hurting you.

 

nope try agian . the air pump and assorted crap including the converters can go they totally choke these trucks .

also dont remove the egr, it runs better with it .

and like prevoisly metioned you need the 02 sensors and the vaccum tank

 

Theres no easy way to get around many of the "epa handicaps" on a EFI motor.

I've read a few other posts of yours about your future plans for your truck, maybe you could ditch the efi all together and run a carb.

 

The stock exhaust system is limiting, though the cats themselves are probably not as restrictive as everybody makes them out to be. The manifolds and Y pipe assembly certainly don't help matters. But the air pump puts no load worth talking about on the motor. Go ahead and take it off, you'll find the truck runs no stronger, been there.. got the shorter serpentine belt to prove it.

 

If you live where they do a smog check and the guy does the visual like he's supposed to, big fat FAIL. Removing most anything will effect performance and removing the air pump will effect the cat and raise your emmisions. If you're not concerned about emmisions pull just the air pump and wait to pull the cat or go ahead and pull it. All the rest has a definitive effect on the ECU even if it's not directly connected. Had to learn all this while I was working in California on U-Hauls. Customers trying to save a buck and they made it worse. You'd be surprised.

 

thanks guys, and no i dont have any inspections here visual or sniffer

 

This is complete nonsense.

You want some advice - leave it all on there. This isn't 1976. Engineers figured out long ago how to put emissions equipment on an engine and not handicap it. Take everything off, and it will run worse than it does now. The computer is designed to run with all the emissions stuff in place. Take it off and the computer won't be able to compensate.

 

besides opening a can of worms you'll also get pisspoor gas milage and no shop will ever work on your truck when its so screwed up it wont run with out all the emisions junk

 

as much as i hate emissions crap on efi trucks like that you can't get the truck to run worth a damn unless you want to chip your computer and what not. you remove the egr it will most likely throw a check engine light same with some other stuff. the only thing i agree on is the late 80s and earlier trucks with carbs with all the emissions stuff. I just stripped a 87 econoline 350 with a 460 with air injection tubes 2 air pumps all sorts of vacume lines and switches and had to re route the evap line from the fuel tank to the canisters and left them that way with no purge lines on them. i mostly did this because you have to pull all sorts of crap just to take a valve cover off to change the gaskets. again though thats a carbed setup not a efi setup so it really makes no diff if i pull it off.

Something else to consider. If law enforcement were ever to discover the removal, the fine could cost you up to $2500 at the judge's discretion and depending on the state.
