Sputtering? Turbo leak? Low blinker fluid?

[muffinstar16]

So today I spent the morning taking my front bumper off to restore my headlights, clean unerring the mount etc. Also changed my oil. As of about 30 minutes ago, my car will get just over 3 rpms and then it'll feel like I down shift. All boost pressure is lost and the car jerks forward. If I roll on the throttle I can get higher in the rpms, but If I try to do a turbo pull, 3k rpms and I hit the problem. Any idea what this could be? Already unplugged the MAF sensor twice and plugged it back in. Still happens.

Have you pressure tested the intake (blt, boost leak test)?

 

[muffinstar16]

I have not. How would I go about doing this?

Thank you sir.
Just in case, as a back up plan, any other cause? Spark plugs gone bad? Need new coil packs?

I had the same issue with mine, check the plugs and your fuel pressure. Check your regulated and unregulated fuel pressure. If that doesn't solve it, then go to the boost leak test.

My wife band Guage is doing the same thing it'd alway been doing, although I could probably stand to replace my plugs and wires for good measure. I'm just about at the 100k miles mark.

Wide. Wide band. Not wife.

I would have to double the fuel pressure, could be pump giving out. do you have any missing links or any kind of fuel cut off installed could be that also.

 

[muffinstar16]

Any info on how to check fuel pressure without spending big money?

Autozone lends a fuel pressure tester kit with a deposit or you could get a cheap one from harbor freight.

if it happen right after taking off the bumper check for any wire that you may have hit or pulled off when doing so, because if it ran fine before that it would be very unusual but not unheard of that other things to cause that problem
