Thanks for replies: Yes the above show vacuum in state I found it when it was rough idling and with yellow pencil I stuck in it which stopped rough idling.
Yes OEM plugs I took 3 rear broken off plugs inside head out with an easyout tool. Phew! and replaced with originals with new OEM.
1st/Front 02 sensor replaced with Bosch NON-OEM, mistake?
Cleaned MAF sensor but not replaced
Fuel Filter likely never changed since it is rusty as hell. I am planning on replacing it ASAP.
BRAND new dual exhaust put in from CAT back No leaks all good there. Manifolds appear to be in decent shape but dunno about gaskets.
Just have to find out where the vacuum line goes yet even though within helpful guys told me it goes to HVAC controller? EVAP? then canister in a long run to front of engine?
LOL My $900 good deal is turning into a $3K nightmare but maybe when all is said and done we can drive it on 3 speeds since OD is shot for hopefully 2-3 years... Shagrin
