Boost Leak or bad O2 sensor?!?

[Shapingo]

I was driving today when all of a sudden my car studdered. The factory boost gauge (the plus and minus one just stopped working, it doesn't move) but my after market one still works. Also I'm running extremely rich and the car feels like it is going to stall every time I come to a complete stop.

I thought at first it maybe was a boost leak, even though I don't know why it would suddenly occur. I don't get the boost gauge just dying though at random and suddenly running rich.

Any thoughts/ help would be appreciated

A coupler/hose could have popped off. Do a boost leak test, they never hurt.

Well, you answered your own question basically. Sounds like your runnin pig rich. Bigger injectors + aft. fuel pump and no fuel control?? Your engine is basically flooding itself. At the very least, get an AFC...standalone is always great.

Exactly. How are you controlling your injectors?? WTF

actually I have the stock 450cc injectors in right now (have for 2 months) Yes i have do a afc (apexi neo)

The problem I think, is a combo boost leak and bad 02 sensor. my luck is like that.

Do a boost leak test and find out for sure.

thanks guys, it was a boost leak. Apparently I must have hit something while driving and a clamp on as lower pipe came loose. The bad part is when I took off that pipe some water was in it. I hope I didn't suck that water into the engine.

Car starts but needs new spark plugs, thanks for the help
