well my idle sounds like i have cams, but i dont. to describe it...it sounds normal but inside the car it seems to shake, and when you listen to the exhuast it hiccups, like when you have cams..what could be my problem?

my mods are dynoflash, greddy type s recirc (it did it when i had the factory dv on too), tbe, intake and mbc

 

I have the exact same problem with the hipcupps but I posted a thread and noone replied 2 monthes ago. Must be us Texans. Hope someone will reply this time for the both of us.

 

I would probaby reset the ECU first and drive around a while to see if it "fixes" anything.

Check spark plugs. might need new ones.

Could also be fuel system. injectors, pump etc.

 

Same here. Brand new IX, 1000 miles. The idle is quite lumpy and there's some good vibration from inside the cabin. It got more noticable when I put on my TBE. I have read that a good flash usually smooths out the idle.

I'm meeting Al for a tune on Wed. I'll post back let you know if it improves.

 

how would i diagnose the problem, ive reset the ecu and its the same.

 

i think it's the plugs since resetting the ecu does nothing for me

 

i got new plugs, coppers and gapped at .24

 

evening bump

 

I have the same problem, had it for a long time.

 

u need to get some NGK iridiums. they are pregapped to .028". the factory plugs are iridium as well. also check all your I/C & vacuum connections. u may have a LEAK...

 

when i dont drive my evo for a week or so then get in it and drive it and be hard on it it has a small lump in it i have a 05 evo and on my 03 evo it does the same thing i think its fairly comin car runs fine tho.

 

bump My car experiences the same problem and I would really like to know how to fix it.

 

car pulls hard, dont think i have a boost leak, all vacuum lines are fine and pretty sure a couple of these guys having the same problem are still running the factory plugs
