Hey guys, I searched and searched but I couldn't find anything that addressed this issue similar to mine.

Mods are

WORKs tune
UR turbo-back
ETS 4" intercooler package
WORKs drop-in

No other mods and I started having a lumpy idle about three weeks ago. Changed out the spark plugs to new OEM plugs and it didn't get rid of the idle issue.

My friend is saying that it could be a boost leak, others are saying it might be a vacuum hose that popped off, even though my friend and I haven't been able to find anything like that.

There's no CEL, nothing is popping up, it just lumps at idle and when I go WOT, it'll back fire sometimes and have a hard time building full boost (it'll still go to redline though)

Please help me out w/this cuz I need this fixed ASAP!!!! Thanks guys!!!

 

so did u actually do a boostleak test?

 

we haven't done the boost leak test yet, going to do that soon. Trying to see if anyone else out there has had this issue and it turned out to be something else, that way I can check in the mean time.

 

i had the same problem, i did a boost leak and i had a hole in the FMIC. i patched the hole and at the same time i got a walbro fuel pump + another tune and it went away. but patching the boost leak most of it it still jumped a little so thats why i did the fuel pump and another tune

 

yeah the boost leak test should prove benificial. i had a similar problem when i installed my IC pipping i needed to go back and retighten them and the i was good (ecspecially the UICP)

best of luck to u

 

Question to the OP did you have a service engine soon light on?
I am asking because what you are describing seems what I might be having issues with.
