2001 S60. I ran Seafoam through the intake per the instructions here: https://www.matthewsvolvosite.com/2010/0 ... -followup/. Lotsa smoke! The idle was irregular before (drops, then rises) but now it drops so low as to almost stall every "cycle". The interior lights dim and everything. Did I break something?
CEL light is on, but it has been for a while (trans is bad, getting fixed soon) so I've been ignoring it. I pulled the code now and it's reading PO237, low input voltage for the turbo? I reset it and it comes back on immediately.
Seafoam...now idle is horribly irregular

Hold the idle steady with your foot and check the alternator's output voltage. Low voltage can cause all kinds of weird things to happen.

The alternator reads perfect, right around 14.5-14.8 or so when idling. Battery is strong, 12.5v.
It idles perfectly when cold but the idle gets all wavy when it's warmed up. Drops to 6-700 the pops up to 1k. Every so often it drops so low as to make the whole car judder. Man, I thought seafoaming the intake was supposed to FIX this.
Codes come back immediately after clearing too. 237 and 236. Ugh!

May have messed up the MAF
(Or it was going bad and this helped it along)

Those codes could point to the MAP sensor; maybe the seafoam didn't agree with it, or maybe you could check the wiring/connector to the MAP.
Hope this helps.

Yeah, I touched the sensor when I picked it up, think I broke it. Ha! It's much worse now. Time for a new MAF. I was thinking I should probably replace it anyways.

You need to remove the TB to properly clean it
Make sure you buy a new gasket
