hey guys I think I'm in trouble with mechanical issue in the middle of nowhere could use help think it may be vacuum leak if someone could call me 706 951 0213 if possible I don't want to stop and stall out again on 44w

 

update...car idles like **** around 500 rpms.....still will boost 21psi....DV flutters even when still at 5 vacuum in 5th gear.....one time in 5th I was passing a semi at 19 psi.....car jerked and sputters EGTs went from 15 to 12 in an instant. car sputters for a few then returned to normal. Everything looks connected and I double checled everything...i have 400 miles to go. I hope I make it. anyone have any idea what it could be?

 

Check all of your intercooler piping and vacuum lines.

 

+1 your problem more than likely lies in loose piping/broken/loose/ripped vacuum hoses.

if it continues, call CBRD and play 20 questions... i remember seeing you saying they built your new ride.

good luck.

 

possible blow Intercooler pipe off.. check all Intercooler pipes and couples..

 

Check your maf to see it's plugged in all the way. Throwing any codes?

 

poke around at what i suggested zach,

and call me back if you cant find anything..

cheers

Must be an air leak somewhere past the maf. Spray some water and watch for bubbles...

 

So far no luck on finding anything loose or cut hoses. I am beginning to think it could be elevation and the tune for 93 octane since there is only 91 out here. Could that be cause the rough idle and strong jerk under high boost?

 

it could be pulling timing... but when we talked i said DO NOT BOOST IT on 91... turn the boost down... you were tuned for 93

but still sounds like a leak.

another suggestion, if your car is barely idling, you know something is wrong with it, NEVER boost it. your just asking for very expensive repairs.

 

what altitude are you at? if you are tuned for 93 octane why are you still boosting 20+ lbs on 91 octane? altitude makes a huge difference. i'm guessing you may be at a fairly high altitude. the fluttering you are hearing is most likely the wastegate trying to control the turbo which is trying to overspeed due to thinner air.

 

yeah about 5k ft higher than the norm. I had it tweaked and fixed for altitude and octane. Running good again though, I checked everywhere for leaks before hand and found nothing, but all is fixed for now. Thanks for all the input and suggestions.

 

yeah,

you had called and caleb said at the least turn the boost way down... then you said it was hesitating at high boost on 91...

our tune was for 93, we went over that....

regardless.... hope all is well now.....

cheers

I did turn the boost down, ran into issues here in AZ with the hills, i could not get up without getting to about 10psi thats when the problems would occur. Its all good for now just gonna have to get retuned when i make it back to the east coast.


EDIT: The high boost was the first time the problem occured, i did not keep hitting 20psi after the intitial problem.
