Well, I just checked plug gaps... all 4 were left at over .040. So I gapped them to the proper .028 (which is correct for the 1.8l too). The COP's are mismatched, 2 look factory 1 looks replaced a while ago & 1 looks relatively new. One of the factory boots is loose fitting, it slid off & on the plug with almost no resistance.
Worse yet... 2 of the 4 connectors on the harness look different: 1 is missing the little yellow plastic under the metal contacts & another has the plastic ring broken around the contacts. I did get it to seat fully & I could feel the connectors slide onto the tabs, but it's not right for sure. I didn't follow it back to see if there's a master connector before it goes into the main harness... anyone know? Wondering if the connectors can even be found to buy replacements.
Anyhow, after I did that I started it up & let it come to temp & it made no difference at all in it's idle drop out.
I did run around both town & highway driving earlier with the scanner recording. I'm amazed it isn't throwing a misfire code, but it's not. Looked at the scans & I don't see anything that looks off, though I'm not sure some of what I'm looking at.
So next I'll check the TB & plenum & probably pull the ISC & clean it...
