So, I've been noticing my IX seems to run very poorly in the mornings when its cold outside and the engine is cold, once it warms up its fine. but this morning, it was really bad...if i keep the rpms up, it'll go, but don't want to be reving it when the engine is cold.

is this due to 10%ethanol in our gas now? Should I get retuned to make this stop?

 

No it would be that you need to let your car warm up before you go out and getting on it....

 

go start your car 5 mins before you leave.

 

Yeah.. .this is really pronounced if you have a different intake set up. The car runs really lean if you just start it and drive (you can see that if you have a wideband).

 

When i purchased the mitsubishi new from the dealer... they told me Mitsubishi Factory recommends that you let the engine warm up AT LEAST 2 min before driving everytime!!

 

Even in my 8 manual its recommended you shouldn't move the car until the temperature needle starts moving.

 

wake up 6 minutes earlier in the morning... that will give you 2 min. to get down to your car and start it... then go back inside...pour a cup of coffee...look at the funny page. that will give your car 4 min. to warm up...then drive to work.

 

I usually wait like 30 sec. and then won't really go at it until my factory water temp is up to the normal point

 

ok, just to clarify, i never get on my car until the temp needle is in it's happy warm place...what I was saying is the car on some mornings will now only stop sputtering if I keep the revs up, which is new, and is a problem - thus my posting. So, if this hasn't been happening, and now it is happening, that strikes me as strange and not normal - normal being over the previous 13000 miles it not happening.

Ok, got the point about letting it warm up, but still - why the change all of a sudden? I guess that's my question.

 

vacuum leak--- something is making it run lean--could be temp change as well from your last tune till now..

 

Could be your throttle body shaft seals going out....

 

Why don't you feed the shaft seals?

"<sigh> But the shaft seals are actually a series of interlocks and safety mechanisms that ensure the integrity surrounding the ships main propulsion shaft, and not nautical mammals; but I'll go feed em if you want."

Oh, the force is strong with this one.....

 

Okay I couldn't help but put that in there, and probably only the Navy guys will get it.

Anyway..... without knowing much more about the car I guess that's what everybody assumed. I know that once I put my AEM intake on, it ran really crummy when I first started it if I didn't let it warm up before. Also, maybe your spark plugs are due to be changed out. I know that when mine were due, it didn't run as well when it was cold. Factory recommends every 30k, but I change them every 15k and it seems to help them a bit.

Just a thought.

 

Mine was doing the same thing in the am/cold mornings and i had a boost/vacuum leak. Do a boost/leak test.
