95 == CPI motor so the throttle body points out the front of the engine, not up like the 96+ SCFI motors. And with the SCFI motors, you have to disconnect the MAF sensor to get the engine to run at all with the rest of the intake duct work disconnected. The MAF needs the air to flow across it to work properly.
If you have a vacuum line at the throttle body, use that to pull the seafoam into the engine. Use another section of vacuum hose and drop the hose down into the can of seafoam and squeeze the line to control the flow. You do not want the engine to stall out for the first 2/3rds of the can. On the last 1/3rd, allow the engine to stall and then sit for 20-30minutes to soak.

I just used their "deep creep" (seafoam in an aerosol can) and sprayed it into the throttle body. Worked great. Vast improvement and a great smoke show.

I have a 98 blazer with a hesitation problem when throttling up...specially when it rains, which clears up eventually if Im driving long distance....it's annoying though, and this morning on my way to work, check engline light came on, with code 300...random misfire...would seafoam help me? Also, I'm starting to pick up the whole unplug vac line and hold it with thumb till ready to pour in, but on a 98, which line am I removing exactly? Am I removing anything else? Fuel pump and filter are both recent (6 months ago) as well as my cat...fuel consumption is nice, really cant complain, and the oil I still can see through it even 5000 miles later...so really Im only worried about getting the throttle itself cleaned out. Anyone have any pictures? Thanks.
