rough idle on cold days?
when my evo sits overnight in the cold. it idles really rough for quite awhile.. it generally stops after it warms up...
is it because of my mods and no tune?
Turbo XS Intercooler
HKS SSQ Recirc Blow off valve
AMS Intake
HKS Downpipe
HKS Hi-Power Exhaust
Tein Springs
HKS Turbotimer
Go Fast Bits Manual Boost Controller
Autometer Boost Gauge

My car idles rough too in the mornings. I takes a while for it to warm up. I need a tune too though. My motor is fully built bored .40 over so im sure that has a part in it. But i hate the cold as much as my car does. 93 octane

500-700 it shook bad and felt like it was going to die...
throttle response was very bad..
If I was on the throttle, the turbo spooled to double the boost it would normally be at for that amount of rpms...
If I gave it too much throttle it would 'stall' like a fuel cut feeling and back fire.. that was at only 4000 rpms...
after driving it for 15 minutes it came out of it and drove normal..
only happened once and hasn't done it since..

my car runs like crap when i start it...i leave mine for about 3-5 min before it idles smooth... i guess this is more common than i thought... my rpms jump very high though...when i turn it on it goes between 500-1500 jumping up and down...and also starts slowly holding the rpm up to 2000 for a few seconds before dropping back down again...hopefully itll go into the garage soon for the winter lol
My car idles at about 1800 when its very cold, as it warms up steps slowly down to 900 and idles pretty consistent.
I didnt think an evo would even stay running if it tried to idle at 500rpm.
