Hi guys and girl's , will I'm new to the Mitsubishi community I did have a Subaru WRX .the reason for this thread is because when I'm driving my car rev's up and down when it's around 2000rpm not much but you can hear it and see the needle moveing up and down but what's weird is it's not much,I hope some one can let me know what it can be for I can fix it please and thank you

 

i have also come from Subaru WRX chocolate pistons in the 2.5 ring land

mine also did that with throttle when i first had it but has not done it since i have done the ecu flash and the sst flash

ecu flash


sst flash

 

Thank you so I would have to get a tune to fix it

 

Use the tc-sst switch and see if you have a s-sport mode. If so you have a mod on your car that causes this when cruising in 6th gear...it's harmless in this scenario.

 

I'm sorry I didn't mention I have a 2010 ralliart and the only thing I done to the car is put a k&n drop-in filter

 

It's a reflash mod, no ralliart comes stock with s-sport mode, you may have bought the car with the mod done already...what you are describing sounds very similar.

 

that's very interesting I'm gonna try it thank you for your input I will let you know if it does have it

 

Engine running/stopped/foot on brake - If you hold the sport/normal switch for ~5 seconds - does the "S-Sport" appear?

 

Thank you! Forgot the procedure for turning on s-sport had to be stopped.

 

ok thank you I'm gonna try it today

 

Not only do you have to be stopped, but I believe you also have to have the gear selector in "Park" for it to switch over to S-Sport mode. Then press the "sport/normal switch" forward and hold for about 5 seconds as was stated previously.

 

I tryed it the same way you guy's said and I don't have it ,but I did looked at something I took the heat shield off and looked at the manifold and it looked like it was cracked in two places and welded so I looked even more and found I'm missing 3 manifold bolts so I was pissed , so now I'm gonna get them bolts and put them on I think they are 14mms

 

sorry three nuts

 

it's the three closest to the turbo the driver side I know some nuts are 10mm X 1.25mm and some are 8mm X 1.25mm I'm just going to get three of each just to make sure
