Check your plugs and plug wires. Also look for boost leaks...

Build one of these: http://www.vfaq.com/mods/ICtester.html ;)

You can also check the IC pipes to see if they're making a solid connection and if the clamps are tight enough...

Don't turn the car on...

You need an air compressor so that you can build air in the system real quick. If air doesn't build in the system; it means that you do have a big leak somewhere...

This will explain it to you a lot better: http://www.dsm.org/menu.epl?item=494 ;)

Take off the intake hose and put the rubber cap on. Then follow the following...

"I just cap off the turbo, put a pipe between the turbo and the side wall of the car so the cap doesn't pop off (it tends to pop off at 22psi no matter how tight I make the cap). Cut the bike pump hose and put a long silicone hose on the end of it, and T that hose to your BOV line. Then put a screwdriver in yoru TB to keep the plate open.
It takes me about 25 pumps to reach 15psi. If I pump 25 times and I see 0 psi? That means I have a huge boost leak. Usually, at 20psi pressure,your psi should bleed down very slowly, meaning you can run from the engine bay to your boost gauge and still see psi. That's ok...
So what was leaking on my car? I had a slit on the bov line that would only leak at 18psi, and I mean leak! So I fixed that. I go to ATCO to race, all good. I come home and just notice the car lost its edge. So what's next? Another intake pressure test. This time, I couldn't get any pressure. I went looking and could hear air rushing out the back of the intake manifold. What was it? My EGR side vacuum hose just was dangling there! Things that I had no idea or didnt expect, just happened out of nowhere. Well, got it back on tighter, and my idle fixed itself, and my gas mileage went up.?
