Hissing is ok. Good work on performing Tony's test. Hang with us and you will get this. We were all noobs once - even Tony and Targalid.

Spray around the injectors where they connect into the intake runners. Also, the intake runners both ends. Around the rubber sleeves and where they bolt onto the heads. The head interface is where I had a two year PITA unmetered air leak. Made my car put-put-put slight muffled backfire when it idled.

Check the airbox over for cracks. Do you have a pop off valve installed on the inside of the airbox? That can leak.

What is the rpm range when it is surging? Does the exhaust stink like gas?

Do you have a tool to adjust the CO mixture? How many tools do you have available? Do you have an air compressor, dremel, vise, etc? Do you park your car on the street with no garage. Asking because there are limits to what you can do without tools or space.

How about the hoses that connect to the oil tank? You may be able to feel them for integrity rather than going nuts with the spray.

There is a hose that goes from your engine all the way to the brake booster in the front trunk. That can be a stinker sometimes and can crack near the transmission. Try finding that one if you are a newbie - LOL.
