hey all, will i got and down pipe (test pipe) that i bougth off online, and now i'm putting the stock down pipe back on. Now when driving the car, the car is leaking off, like the car is going to die and the rpm and mph will drop down on me. To me i think it is the o2 that is doing this or somthing because this never happenend to the car before but know it is. Also all i can say is that it seem like there is no fuel coming in or not. i have to trun the car off and trun it on again so that i car will be back the same as is. Help to all.

 

The car is "leaking off"? What does that even mean? Is it dumping fluids at certain RPM's?

 

Any codes?
