I think this is what they are calling an evap solenoid Here.
If you can read the OEM part number off the solenoid you have Rockauto has a crossreference search function.
Yep. That's what they're calling the EVAP solenoid. I bet it would work for my EGR too.

Ok so I replaced the EGR solenoid and EGR is functioning now. Fixed the EVAP leak and passed the EVAP test. But I failed the smog. The only driveability issue I'm having is hesitation when I first hit the gas from a stop. I came home and checked the flash codes and I've got 34 and 52. I already put a new VSS in. I'm going to take a look at the VSS circuit and see what I can see. But I have no idea what the Internal Control Failure is. I've got high HC and CO Nox is good. Lambda calc say's it's at .729 53 Internal control failure 34 Speed control Solenoid circuits

But There is no reason to replace a part that has not been deemed bad. That's the main problem I have with your suggestion. I don't mean to sound rude or unappreciative but I need help that is based in logic. Not just swapping a part because that's your guess.
Again did you diagnose the back pressure EGR system correctly? Its not about a guess. Its a guess on how many other parts you want to blame/swap and none fix the problem. I try to help.

http://www.allpar.com/fix/codes/faults/code-51-52.htmlBasically, running rich, which your smog test agrees with. Not likely the O2 sensor here. Run thru the driveability troubleshooting guide on the link. Might be something like coolant temp sensor stuck cold or similar.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

I know you probably can't in Cali, but I yanked all my smog off an 88 R/C I had and it ran 10x better and still avg'd 17.2mpg combined. I had the same issues, ran like poo poo sputtered, hesitated, I could tune it out so I yanked all the unnecessary garbage and problem solved. Ya I wouldn't ask my friend to pass a truck like that so I would be looking at paying $100 extra every other year to bribe some other smog tech to pass it. I would rather just fix it right. I swear it's running hotter than normal and it boiled over when we did the smog. I'm sure it wouldn't have boiled over if we had put the fan in front of it but oh well. When I worked there we didn't bother to put the fan on unless it was really hot that day or the vehicle looked suspect. It didn't really get that hot and it was clean so the test was short. But it did boil over after he turned it off. And it was leaking out the radiator cap. No other leaks. Made me think bad radiator cap or bad fan clutch. But the radiator cap is new. I cleaned it off and topped off the coolant and drove it all around today. It runs perfect on the freeway but when I get stopped at a light it doesn't overheat but it does seem to inch up a little bit. Makes me think fan clutch. Also, everything else it new. Cap Radiator Hoses Thermostat CTS Water Pump Other than the running hot issue it does still have hesitation on acceleration at low speeds, on the freeway it runs perfect. It almost feels like I'm driving with the E-brake on until I get past 35 or so. Feels a bit underpowered.

But runs perfect with the EGR capped off.
Clue 1. Oh, that's helpful.

Swapped out the fan clutch and the running hot is fixed. Still has hesitation on acceleration but I've got the EGR capped off so it's running perfect. But I still want to find out why the EGR is too much or too soon or whatever the issue is. I have tested the EGR valve itself for operation with a vacuum pump and it makes the engine shutter when I apply vacuum directly to the EGR valve. The solenoid is working giving EGR only when it hit the gas. I'm getting 18-20 lbs after the transducer when I give it gas. Not sure what else to try. I noticed today that the back of the oil pan was covered in oil again. I noticed when I got the truck back not only was the timing off so bad it was backfiring it was also over full on oil. Oil is up over 1/2 in past full. Is that really enough to make a seal fail? I don't think it is and I'm hoping it's just the oil filter plate leaking again but Idk. I cleaned it all off and drove it around and don't see anything yet so I'll have to drive it more and maybe get some UV dye to figure that one out.

Yea I know I could just leave it how it is now but I want it all fixed up right. You can get a historic tag in cali too.
"These special plates are issued, upon request, for motor vehicles manufactured after 1922 which are at least 25 years old and of historic interest." -CA DMV
But my pickup is only an 89.
/And actually unhooking your EGR will cause it to fail for NOx most likely. But ya I could hook it up for the test.
