Heres the Story....

Driving to a freinds house for a baby shower, get on the highway....all fine and dandy....10psi, no problems. Car is driving nice.

Stop at a red light, give some gas, car seems to be a bit sluggish and its sounding 'farty'
Cant really explain the sound, but its almost like its miss firing or something....not sure.

Shift, see that the RPM's shoot up more than normal (I have a leaky BOV and it does cause the RPMS to shoot up a little but not this much), so I'm thinking "Ok, I gotta leak somewhere, no biggie, I'll check after the shower"

Well, I took out the battery, took off all the plumbing going from the TB to the IC. Noticed that one of my couplers were cut, it was rubbing aginst the Rad support brace, so I change it, and actually reinforce the new one with 2 sheets of aluminum around it. Put everything back together, checked the vaccum lines going to the wastegate & BOV, and went for a rip.

Same problem happpened.

Any help appreciated guys


Another thing was the car wasnt buidling boost as quickly when I was driving, but it did eventually reach 10psi.....

if you have a boost leak you won't make as much boost
Thats what I figured. And usually you can tell the sound between boost leak and this. The car just sounds sick.

check your plugs and wires... Farty sound means miss, usually.

farty sound can also mean bad fuel filter, upstream o2 sensor gone. I had the farty sound and it was a [censored] o2

Update...

Went for a coffee this morning...

Car seemed to be driving fine at first but after it warmed up a little, enuff for the guauge to move less than a 1/4 up the scale, the car started to do the same hesitation, farting stuff.

Do you have real bad hesitation? Also how are your EGT's? Do they go high when the farty sound starts?

Im taking it easy, but yes I can feel the hesitation being pretty violent.

I have no clue what my EGT's are. I have no logger/guague to tell me so. It does get pretty hot in there. Especially with 96f + humidity weather lately.
