Initially, where is it? I just bought an 89 Camaro RS 2.8l v6. I don't know much about car as it is. I'm trying to fix that. I have every 89 Camaro repair manual I could find on the way.

From what I've been reading, there is a good chance that I have a severe carbon build up problem. I bought c-foam to run through the carb to see if that will help with the problem.

I can't find the main intake vacuum hose that I am suppose to pour the c-foam into.

"Performing a Sea Foam Engine Treatment on a Fuel Injected Engine Begin by parking the vehicle in a well ventilated area. Locate a vacuum line that you are certain DISTRIBUTES EVENLY TO ALL CYLINDERS. On many vehicles the easiest option is taking the vacuum line from your brake booster PCV."

 

It is fuel injected, on the rear of the intake, look for a large black vacuum line that runs to the break booster. It is a T fitting with a plug on the opposite side. Remove the cap, attach a long piece of vacuum line and put it in the can. Just bought an 88 with a v6 for my son's first car and did this to his. Smokes like heck but seems to help. I run Sea Foam in everything I own.
