drive the truck and once you get home open the gas cap and see if it has alot of vapor trapped in it. If so i bet your evap can is bad. the can shouldnt really make your truck run that poorly

it always does that and it has been running poorly for a while. It idles rough. I can't get a full tank of gas in it anymore either. I tried to seach the forum but only found a little bit of info regarding 2nd gens.

Have you done the small things like plugs wires cap rotor fuel filter? That wont make it so you can fill your tank the whole way but it sounds like you have trapped vapor in the tank aswellor maybe a bad filler sensor. when you go to fill it with gas does it sound like the tank is airing out when you take off the fuel cap? Do the small things as well because that may be why you have bad idle

It has the following:
New wires
New plugs
New coils
Cleaned MAF
BG intake cleaning
BG fuel injector cleaning
New fuel sending unit
I cleaned the throttle and IACV even though they were spotless after the BG intake cleaning.
New PCV valve
Seafoam treatment.
I am thinking that it may be the canister since that seems to be a link and how it was hissing all the way through the night to the next day.
I wonder if I can just gut it?
My friend did that on his Elantra and it worked.

I don't know how you could test one on a Toyota but at GM we push nitrogen smoke through the EVAP system and do a purge/seal with a scan tool to diagnose any EVAP problem. I would highly suggest taking it to a dealer or a shop with a smoke machine.

new symptoms, when first starting when it is cold, it idles normally. When I shift into reverse or drive it starts lugging over and surging. It does this until I step on the gas. As soon as I give it gas the surging goes away.

Top of my head.. idle air speed control valve needs cleaning,you said you did this though?Might have to take it off and really clean it....or,possibly low coolant as well.(older trucks more sensitive to this vs. newer ones.) Vacuum leak leak could do it as well..while its surging spray little bit of carb cleaner on hose connections engine side of throttle body butterfly.

Ah, I wondered what that was under my hood. When I first got the truck and was messing around under the hood, I thought there was a bee nest in it. It had been sitting in the PO's barn for a month before I bought it. I did quickly figure out it wasn't bees but didn't know that it was

Still does it, goes bzzzzp bzzzzp for a little while, I haven't timed it, after the engine is turned off.
It comes from a box on the fender well just in front of the brake fluid container. Is it NOT a normal noise??
