1992 Galant fuel delivery issue?

[Doc8404]

new O2 and fuel filter this coming weekend....
and now i have a SLIGHTLY high and erratic idle.

no idea if (or how) it's related to the ARX treatment

well, o2 sensor didn't make it in...totally stripped, heated with torch, etc. bolt in there for now.


new fuel filter ...NO hesitation/surge anymore.
not sure which it was, the O2 or filter. the filter was new after the junkyard tank (with lots of varnish...) I'm thinking the Techron dissolved it all and put it in the filter, that gas was nasty coming out...

now to tap a cast iron manifold!

after looking on rockauto.com, the manifold with both gaskets and new hardware was $77....just the one gasket was $16...so, i figured I'd just pay for the manifold/hardware kit instead...that way, no tapping and I'll be sure the O2 sensor fit...expensive lesson considering I'm now driving around with the CEL on the whole time and she runs/idles like a champ.
