I'm S/C
New TB gasket after a cleaning a while back, new upstream O2 after PCM threw a DTC. I don't know how it was still working up until then. Looked like the end was welded shut. No O2 or anything else getting in that thing. Took a can of PB and a 4 foot breaker bar to get it out lol. I should probably do the downstream as well, since I'm getting intermittent P0421 cat efficiency, but only after changing the upstream. Makes me think it might not be the cat
Wow, I really should do the LIM yeah. I run G05 coolant now, but previous owner left original DEXCOOL in for 130k :/
It's gonna be nasty.
What should vacuum be at idle? I'll go take a look at what I'm showing. Thanks!
