when at a stop and idling my evo 8 drops below 1k idle for a split seccond and jumps back yo idle at 1 k any sugg or ideas its like it wants to stall though it never has well yet that is

 

guess i have a pos car

 

Do you happen to be running a VTA BOV? Or anything like that? That will def cause idling issues.

When does it happen? Like all the time during idle or going from a light to light?

 

My TurboSmart Dual Port BOV did the same until I adjusted it correctly.

 

my evo is bone stock and i mean everything is stock and it happens all the time cold or warmed up interior lights also fade when it bogs maybe a bad ground ?

 

the owner before me removed the aftermarket stereo he had before selling it to this is driving me crazy

 

i have the same problem. spark plugs maybe?

 

maybe all the silver ones do this lol ?

 

you normally idle at 1k? Warmed up? Perhaps the 8's and 9's are different but a bone stock (9 at least) idles between 750 and 850 when warmed up. You may also want to look into the possibility of the ECU being flashed. The previous owner may have kept it stock, but still flashed it (poorly?). Who knows.

 

no he was **** about the car he was a 45 year old man how do i go about getting it flashed ?

 

Have you been around other Evo's.. fluctuating idle is pretty normal. Do you have the AC on?

 

Wouldn't hurt to flash it back to a stock map just for piece-of-mind. The previous owner being **** or not, I would want to make sure. Another possibility is the idle adjuster screw was messed with if the car was previously tuned and then put back to stock. Might as well check your vacuum hoses too while fiddling around the intake.

Trust me, it happens. I was told my car was NEVER modded when I bought my evo. Turns out that was a complete lie once I started adding parts.

 

what spark plugs do you recomend ?using ? and what is the torque specs ?

 

no a/c i rarely use it also is there any tips to get the optimal gas mileage ? im fine with the stock power
