My smog pump locked up on me last night, so I yanked it out and pulled the veins out of it. All the bearings were fine, so I cleaned and greased everything then just reinstalled it until I can get a delete kit. I've got an interesting stumble under light load now, and cant figure out why. I didn't plug or remove and of the hoses going to the pump, figured they wren't serving any purpose but they're in tack so it's best to just keep them in place. I've searched around a bit and can't find anyone else with this issue, am I missing something here? I didn't disconnect or disturb any of the vacuum lines, and I verified everything is still hooked up, so i'm thinking that's out. Is leaving these hoses hooked up causing unwanted air/exhaust flow somewhere, possibly? Anyone else ever have this issue?
