Just a quick update- I think I found part of the problem. I found the stumble- turns out I had a defective spark plug that didn't make it self apperent until the insulator started rattling around the contact. I got a platnum set and no more stumble so far. Must have just come loose last night after doing the lines. It seemed fine all the other times I checked it.
Next- It seems I have a vacuum leak at the booster- actually the plastic outlet part for the vacuum connections, because the booster checks out using the brake pedal- but I inadvertently tapped that part reaching over it and it hissed. Would this be the reason for the blower only going out the vents when on full blast, and part of my vacuum troubles?
Now, before this, I had the vac gauge teed in where I already had to make a connection on the manifold/pcv
line (see my awful drawing- sorry used my phone to draw it :) ) the pic where I hooked it up, as well as the MAP
line. It was reading a steady 10.5- that's subtracting 1.5 for the needle being at 1.5 ambient. When I blipped the gas the needle shot around for a split second, then down and slowly up to about 11.5. Same steady reading at the MAP
. Put it in drive and the needle flipped around then back to 10.5. I disconnected it and was poking around which was when I noticed the hiss from the booster outlet. I capped off the vaccuum to the booster and started it up- still rough idle, not much change.... It started raining so I didn't check the vaccuum again with the booster plugged yet to see if there was an improvement there. Will do in the morning. Al so I guess I'll recheck cam timing since maybe I didn't do it right the first time- sorry, still learning! But I guess low steady vacuum can indicate bad valve timing and thus cam timing?
So could there be an additional leak causing the rough idle if its low when I check it with the booster plugged?
Oh- NAJ- thank you- I didn't think about checking that line for the HVAC
, I will do that next too!
