-On my way to school on tuesday, the car bogged getting up to highway speed. A CEL came with the bog, as well as, my boost dropping from 26psi to 10psi. I got home and shut the car off until today since a friend came to read the code it threw. The code said "3 way catalytic converter" so we cleared it and the car was running fine again.

-Used the car again about an hour ago and the same thing happened, car bogged and now i'm down to 10psi. what could be failing? could it be my cat? i have the perrin downpipe+cat

 

hmm, try checking your plugs? Maybe they are really badly fouled and their causing the car to misfire and backfire really bad so it cuts fuel, its a possibility

 

I have full engine power, but just no boost when that CEL comes on. I guess it's like limp mode so it limits my boost. could that still be the plugs??

 

Do you have a o2 spacer installed?

 

Have you checked vacuum ?
