So i went away for the holidays and left the Evo home. It was only two weeks to i thought nothing of it. I did put more air in the tires, left it on a soft surface more than 1/2 tank of gas.

I got back thursday night but didn't start her up till friday. She started up fine, I let her warm up good (15 min). Didn't do any WOT pulls that day or saturday that i was driving around. But last night I made a food run at 3am and decided to go WOT and car started stuttering. It was like she was trying to clear herself up, a fast pop pop pop pop pop sound. I have no clue what this may be, car was running great before all this. Any help or ideas would be greatly appreciated.

 

Check to see if one of the IC pipes blew off.

 

If one blew off it wouldn't boost right, Correct? and it's boosting fine.

 

spark plugs...?

 

Check your fuel pressure regulator vacum line. Otherwise maybe try and put some new gas in it. Ive had some friends with their sport bikes saying their gas has gone bad in 2 weeks time. I find it crazy but you never know worth a shot of mixing in some new plus some octane booster.

 

It is happening to everyone around here in the NE. Just check all of the threads.

The Artic air is causing it. Some are regapping the plugs shorter.

All I did was turn down my boost.

 

If you haven't filled it up with gas I would do that, maybe add some cleaner or dry gas?? I'm guessing some moistur got in the fuel the weather's been crazy the last couple weeks up here with snow, temps in the teens and then about freezing at points.

x2 ı had a sımılar ıssue check the gap on the plugs

 

Don't let it sit and idle for 15 minutes.

 

X's 3 on this.

 

Yeah man it's the plugs. It's happened to me before also.

 

cold air is denser there for it makes the car run leaner than when is warmer and the car will knock. Lowering the boost would be your safest bet.
