? after FAST install
I've got a question. I just installed a FAST 92. I am pretty sure everything was done correctly. I did the Spin mod to the back of the intake to fit. During the test drive a got a Check Gas Cap light on the DIC. It idles good and runs good. Cap didn't feel loose. Coincidence? Or a problem with the install? Feels strong and pulls hard.

I believe you have a problem. Do you have a code reader and are you getting a code? If no code reader, you can disconnect the battery to reset the computer. However, I would guess you have a air/vacuum leak and I would start trouble shooting by inspecting your work.

After my FAST install and test drive it threw a code/check engine light. The code listed the gas cap as a posible cause. I rechecked my work and sure enough I forgot the short vacuum line in the front near the MAP sensor. I then reset the computer by disconnecting the battery and it has worked fine for about a year now. And you said the DIC actually displayed the gas cap info.

My MAP sensor was a little loose. I sealed it up. I am re-installing the manifold this morning and I'm going to watch everything like a hawk. Thanks for all of the input.

So where the MAP goes into the intake can't be it? I completely removed the black plastic line that runs along the intake. I don't see any cracks. It was hooked up . Could I just run some 3/8" rubber hose in it's place to see if that remedys my situation?

Well i swapped out the hard lines for some soft side hose I had lying around in my garage. Reset the computer again and problem is gone. So far anyway. Crossing my fingers.
