Acceleration problems / turbo

[dj675414]

Good day to all you srt-4 techs out there

my srt-4 just had new spark plugs put in by the dealership (did it cause they looked out for me a few weeks back) about 30 days ago. Suddenly im having an issue when i accelerate....my car will jump when it hits around 13 psi and it will like knock and drop down to around 7 then i can accelerate again.

its hard to explain the problem and it only does it sometimes....more times then it doesn't when accelerating...if i don't go above 10 psi it wont do it at all...only when im getting on a highway and dropping that pedal.

any thoughts or advice...btw i do have a p0441 error...last time the dealership said a vacuum line had gotten disconnected from the vapor purge solenoid or what have you...but it has come back on about 50 days after my original visit to the dealership.

you guys have helped me a lot in the past...and made my experience with my srt-4 a lot better...thanks.

Hey, sorry man. I can't really help. I'm on here looking for help myself. My car does the same exact thing and is throwing the same code.

You're plugs are prob. gapped to factory specs....you need to RE-gap em to 038.
