I couldn't get my hands on CRC cleaner locally. None in stock here anywhere so I ended up going with Seafoam.

I didn't want to do this in my neighborhood so I went to a QuickTrip near the toll road so I could immediately open it up when I was done, except.. ..there was a cop there.. ..so I waited for the cop to leave and I began..

I managed to undo the Brake Booster with the motor running. Surprisingly it did not idle high at all with the brake booster disconnected. I also noticed my Brake Booster seemed very oily.

I slowly poured it in with the motor running, no smoke came out initially. The motor also would not stall when I poured it in despite being instructed to intentionally stall it with the seafoam. When I finished up, I reconnected the Brake Booster, I let it sit for about 15 minutes. It was a very rough crank to get her back to life. She idled okay up to the tollroad, but when I stepped on it, it felt like I was revving in nuetral for a moment and pure soot just exploded from my exhaust.. ..it bucked for a bit and the check engine light started flashing as I rolled onto the tollway.. .. onto the ramp I opened it up WOT.. ..getting it to about 80 where I just left clouds of smoke behind me, backing out of it as I merged onto the highway.. .. .. where I slowed down to about 50 MPH and prepared for another WOT run.. ..but that was interrupted as I ran across two sheriffs in the median of the highway.. ..and I just innocently cruised on by them at 25 MPH BELOW the speed limit ... I waited about a mile or so and then gassed on it again, this time throttle response was much sharper.. ..but not wanting to press my luck, I got off the tollway a few exits down.. ..1st Gear response was no longer sluggish, no bucking or rough idle.. ..so now we just wait and see until the next few cold starts to see if this helped my problem. (My car was randomly misfiring during cold start idles)
