Oil smells like gas, runs like ***, it ain't even fast,!! WTF!?

I installed my SR a month ago, did the break in period and everything and the motor ran fine for a few weeks until last week.

I was riding down the road last week (boosting) and heard loud *** poppin noise then my car started to run like a$$ (bogged real bad, won't boost, won't rev). I took it apart the next day to find out that the AIV plug is missing so I plugged it back up. I started it back up and it ran ok (still bogged sometime but not as bad...drivable but running really rich) so i decided to drove it for a few days. Until a few days ago, my friend came over and told me that i should try and took out my 02 sensor and see how it runs. It ran a bit better until i decided to test boosted it again and heard another loud popping noise. I pulled over and my car died on the side of the road. This time the car won't even start without mashing on the throttle (seems like it's just dumping fuel and getting no air). If the throttle is let off...it'll die. All the Spark Plugs has been tested and they were fine, I pulled out the dipstick to check the oil, it was fine but i smell gas on the dipstick....wtf? I stated the motor up and try to test the injectors by unplugging them one by one and see how the motor reacts, injector 1-3 makes the car bog which is normal but when i unplugged #4 injector nothing happen.....

What could be the problems here guys??I apologize for posting such a long post but i'm really in a bind. Any kind of suggestions are appreciated

BTW, the motor is bone stock except for the exhaust mods (3" downpipe and Apex N1) and running stock boost

Peace and Thank you

if ur oil smells like gas, i would think u have bad rings or a hole in one of your pistons. do a cylinder leakage test. that might narrow down the variables. sounds like you have multiple problems. goodluck.

yep, fanta is right, I'd do a compression test first, if the #4 cylinder has a hole in it, it won't fire and the gas will mix with the oil. Sure hope it's just some fluke though. Good luck to ya.

oh yeh. if you get a number thats really low on one of the cylinders, its probably rings going bad. if you get nothing at all on the gauge, its probably a hole in the piston.

where was the popping coming from, the engine bay, or exhaust? If its the engine bay, that would probably be the sound of #4 leaning out way too much and gettin holy.

good luck man
