Exhaust sputtering and engine shaking

[Kiraush]

Rain or Shine, Cold or Hot, if I start up my Supra the exhaust has a light "putt putt putt putt" noise coming from it, and the engine is shaking a bit.
I just had my power steering pump "explode" and had fluid all over everything under my hood, riding without power steering right now as I'm hesitant to buy a new pump (150$) when I need to tend to stuff like this.

I was thinking maybe a spark plug is gunked up with PS Fluid, so I'm checking those tomorrow (Bit dark to be doing it now)

But that's the only idea I have of what it could be :1zhelp:

Edit: I do also need a new o2 sensor, if that could cause it?

What's it idling at

Fairly sure it is idling at 1,000 and keeps dipping down to about 900

Check for ecu codes before anything. Is that idle speed warmed up or cold?

PS- I have a brand new direct fit Denso O2 sensor in the box.
Lemme know if you want it.

I would also suggest to get a timing light and double check the timing. I fixed a supra yesterday with similar problems by realigning the cps and timing it correctly.

Does it stutter on acceleration? If so, I would check the spark plug valley for contamination- especially water.
ANY water in the spark valley will cause a misfire, and it will also cause the "put-put-put" and shaking you mention.

I think my grandfather has a couple laying around his shop, he keeps a few stocked in case any of his go out.

It's done that like twice, once a couple weeks ago and once a few days ago.

When I noticed that it was cold, but I am about to go buy a few parts so I'll check and edit this post accordingly
