"Big Pappa" :Do you have the stock carb ? The guy at Napa said his book showed 2 or 3 solenoid for that year ! So what I did is took mine out went to pick a part and took a few from some cars with 22r motors tested them and put it back in !! It wont take much to plug your cat bad sensor bad solenoid = bad cat
I copied and pasted your response here since it might help someone else out with the same problem. I CAN hear the solonoid click on and off when I unplug it when it's cold. So, that means it's working right?
