OK so ive had this a couple time it is no big deal and is not affecting anything while im driving down ther road crusing at any speed but anyway i was at a light chillen at idle stopped waiting for the light to go green so i could turn and a big 18 wheeler came by at about 50 mph or so and rite after he went by my car dropped in rpm to about 200-300 and felt like it was gunna stall but didnt the rpm came back up to idle and didnt jump up any above regular just fell down when the truck came by. this only happen when big vehicles come by and im at idle but they have to be at a decent crusing speed and its not all the time, i have an idea of what it is but just wondering if this happens to any other EvoZ out there and what yall did to fix it or just some ideas you all might have about this....

 

Vibrations/noise is causing the MAF to misread. Happens when I am drag racing staging up next to open header V8s and whatnots.

 

Probably happens because the vehicle passing by causes a low pressure area around your car choking it out. Maybe your idle control valve is failing, or your MAF. Or maybe its because you have an intake and no tune for it.

 

thats all new to me ive never had that kind of problem but yea id check the maf

 

haha thats funny. whats really happening is ur evo just **** its pants cuz its so scared

 

are you venting your bov to the atmosphere? cuz that could cause it also

 

having same problem here. I think due to my injen intake with no tune.

 

thought it could be your knock sensor...? jus my .02cents

my friend kills my car everytime he 2steps next to me when he runs open downpipe

 

happens to me too and im fully tuned when im at the track and the v8 next to me is reving my car gets scared but then i usually beat him by like 20 cars lol
