hey just wondering if anyone has had experience with an evo 5 running rich at idle im out of ideas

ive only had this dramas with my worked nissan.

What type of mods if any do you have? Do you know for sure its running rich? sure its not just misfiring? A misfire can give the impression its running rich

100% running rich i know what a miss is and i ve had the gas analyser on it it richens up heaps on deceleration and idles like crap . leaving the back of my car covered in unburnt fuel

Silly question but, have you had it to a tuner to have the tune fixed up? You're in Brisbane somewhere, right? Book it in at Neal Lowe Motorsports in Slacks Creek. They're Evo experts. They work on my car and tuned it 2 years ago and mine's still going strong.

hey disciple wats the number for that place ,good on price

I would assume they would be about $120 an hour on the dyno as most places are.

Although cant help but think if its a STANDARD motor running a STANDARD ECU how are you mixtures out? Unless you've tampered with something then yeah you'll need a dyno tune.

He used to charge me $88/h for dyno time. It may have gone up.

Afaik the boost was upped a bit. I can vouch for his rich claim :p can smell him coming from 200m away and the rear of the car is black!

G'day mate,
hey it could be something simple.. have you check your exhaust/dump pipe sensor... thats how the ecu know what the air/fuel ratio is... Or your mapp sensor / Air flow meter

had is happen to a mate, slamped in new sensor in and he was on his way, if your car has been tuned then its normal for the air/feul ratio to be rick at idle and up until it hits boost, so the fuel is there so it doesnt leen out.. becuase thats the last thing any motor wants. Even mine blows Black smoke at idle, as long as its not blue or a crazy amount of smoke it should be okay?

Let me know any way when you find out :P
