hey guys i have a 06 eve 9 mr, and at anything past 25% TPS the car hesitates or fees like a fuel cute happens 2-5 before i need to change gear and happens again in the next gear,

my spark plugs are new
and i got my injectors cleaned and put properly with new seals
got a boost leak test and there was none
so what else can cause this problem

 

Maybe it'll help. My car was acting similar and RRE found my knock sensor wiring was bad so the car was pulling timings due to false knocks and running rich. Fixed the wiring and my car is running good again.

 

See if you can run a log, that will help see whats happening.

 

What are the gaps for your new spark plugs that you dropped in

 

im running NGK LFR6A-11 and i saw the specs online just now the gap is 0.043" (1.1mm) what do i need to gap it to

 

Pretty sure that's your problem, that gap is way to large.

Gap it around .022-.024

What plugs are those though, are they iridiums? IIRC copper plugs needs a different gap size, never used one before, so waiting for someone else to chim in.

 

0.043 gap is a bit large, as stated above, gap them down as suggested and try to drive the car some more

 

Yep, gap to 0.022-0.024. Had the same issue but at wot at 20 psi, gapping the plugs down solved the hesitation issue.

 

Good lord as far as I'm aware that's about twice as wide as what it should be.

I ran .024 for a while with no issues until I started making more boost and ended up needing about 0.020 to resolve hesitation issues at 30psi wOT

 

Digging this thread back up I had a similar issue with my Evo 5 turned out to be one of the connector to my coil pack had a frayed wire to my coil pack. Only Discovered it when I was Changing my plugs gap to compensate for the hesitation. Ordered connectors from spooling up and rebuilt the connector and add a COP kit for good measure been running fine ever since hope it something others explore.

 

Out of curiosity, how did you diagnose this? Was it visible or did you probe it?
