feul cut....help!!!!!!!!!

[jbencosme]

hey i have what people call feul cut and it sucks really bad
why do i have feul cut and how can i fix??

 

[msp1986]

could be a lot of reasons. Can you describe your problem a little bit more in depth? fuel cut isn't something that happens like a flat tire a bunch of things together or one big thing can cause it. and it will fell like your car literally just hit a wall. the first question i would ask is how much boost are you trying to run

 

[jbencosme]

im runing 5psi.......the problem is that im in 3th gear and i downt shift or put it in neutral and the rpms fall to zero then the car shuts off like the elctricity is still running also.....to turn the car back on instead off turning the key i just pop the clutch and the literally jump starts itself

this is more than likley a vacuum leak.

Is your blow off valve vented to atmosphere?

doesn't sound like fuel cut, your car is just pissed that your are trying to make it idle. bury your right foot into the fire-wall....or look into what they just suggested^.

This has absolutely nothing to do with the topic and it does not help him in any way.

Isn't the msp supposed to cut fuel at 10psi? What's up if it dosent?

 

[SeR_Cyclops]

It just depends. Alot of things are factored in. Air temp, time of day, air density. boost. ect

Well I'm at 7200feet its 20deg I got filter no cats and running 16psi(not running lean) I'm suprised it'll run at 16psi

wait... what?


what have u done to it?

 

[wyomsp]

Ya 16psi is a little much but holy hell is it fast it'll run with evos up here (8,9's) and I check plugs regu?arly they stay with good fuel no pinging so ill run it till it blows then a full build

 

[wyomsp]

Only thing it has is a filter I punched the cats out and I'm running it to the ground lol got forged everything in another block @ 8:1 ready to go and I run it hard as hell daily and its not given me any problems besides slipping the clutch at mAx boost hah

 

[jbencosme]

Is your blow off valve vented to atmosphere?

yea it vents out to the atmosphere and loud lol

 

[jbencosme]

this is more than likley a vacuum leak.

what number dose my boost gauge have to read when in vacumm to determine weather i have a vac leak?

 

[SeR_Cyclops]

Is your MAF relocated?

 

[jbencosme]

idk but its rubbing up against the hardpipe thats coming from the intake manifold...is that bad??

 

[SeR_Cyclops]

Show me some pictures of your set up.

 

[jbencosme]
