Intake manifold gasket change....part 2

[Chrispbrown36]

Strange thing....yesterday I replaced some vacuum lines, nothing looked too bad but figured since I had the hose might as well do it. Changed out the line from the vacuum canister to the check valve, replaced the line going from the EGR solenoid to the EGR valve, and while I was at it decided to put the vacuum line back from the smog pump to the throttle body (hadn't been there since I bought the truck). I was also doing some brake work on the daily driver, so I didn't get a chance to run the truck. Few hours later I had to get some parts for the daily driver and took the truck. Not a single SES light and the thing idled a lot better. The idle was still a bit high but not nearly as high as it was before. I don't know that the smog pump had anything to do with it...but damnit I am afraid to disconnect it now! ha ha
