I am in a warm climate area(arizona and it's about 75 degrees today) and my car does this to for the first ten minutes after starting for the first time of the day. then it doesnt do it anymore for the rest of the day unless the car has been sitting for 3 plus hours

 

****... CEL? already, WTF? i'm starting to freak out....got my X last night

 

this is one big reason i will wait for an 09 model, until the gremlins get worked out.
it always happen with first year models.

 

First year , if I remember right, we had the p0300 code for like 3 years not just the first. only 170 miles on mine and no issue you guys are speaking of. TX weather has been great so for 60s and sunny.

 

Yea, some guys are lucky..some guys aren't. I am still waiting for that P0300 code to trip!

 

I rarely get the idle issue. 1300 miles on my X. I've run the car hard many times with no CEL lights, this includes 2 dyno runs by GST and Speed Element.

 

No, the car runs fine on cold start up. The idle is a little higher as it should be but very steady. The issue is after the car is hot and I stop to run an errand and re-start the car after 5-10 minutes. The idle jumps around from 500-1000 and then the car sometimes dies. It doesn't happen consistently. Sometimes it idles smoothly when hot. I'm friends with the owner of the dealership so I'll wait to see them on Monday. I'm sure they'll be interested to try their new CAN scanners out.

Does anyone know if the CAN bus provides more insight than OBD?

 

Like you said you rarely get this, so you are saying you too had this issue with your EVO-X?
Not like I get it every single time, Just want to have some idea of how many people had this happening to them.

 

People dont need to freak out about a CEL. this is not p300
Im sure he has the CEL because he stalled his car.
You can do that to the EVO-8 and 9. You would need to force a stall.
But if you ever stalled your car before in a EV0-8-9 you sometime get a CEL.
after a few restart, it just goes away by it self.

 

hey guys this is really retarded and not sure if you want to test it out. when you are in idle with the hand brake pulled up. turn your steering wheel a bit and see if the motor revs up. My X does that, really bizarre.

anyway about your dip during idle, i get it also but not as severe. have you noticed any drop in power or hesitation during redline pulls?

anyhow, i think i have a quick easy fix for the problem, i just did it yesterday and it's been working like a champ. PM for more info

hey unowned,

i am making about 240-245WHP right now with 2 simple mods and no hesitation at the high end. Actually for the time being, if you want to fix the hestitation on the top end, it's one quick easy fix. PM me for more info.

I haven't gotten a CEL yet, but I have had this erratic idle. I came off the interstate directly to a stoplight and got this, kind of like the car had big cams. The car is 100% stock. I let it do this for about 10 seconds, then it got annoying and I turned left at the green light. I had to stop about a quarter mile later for another light and the symptom was gone.

It did it once earlier too on the trip back from Cali a couple weeks ago, but not as bad. Blip the throttle and it will find itself. I suspect there will be a dealer reflash for this before too long. I've only had it twice in 3200 miles, but its good to talk about stuff like this so we can figure out what is going on.

 

Here we go again. SES Fun!!!!

 

It's a new platform guys, you can typically expect a few kinks, Im sure it will all get worked out.

 

I made it to the dealer today and the CEL is P1320 - Retard Ignition Timing Fail. As you know catalytic converters don't do much when they are cold so evidently the new ECU is suppose to retart the timing when the water temp is between 45 and 97 degrees F (cold start up). This creates more heat in the cylinder and heats the cat up faster. If the ECU senses less than 3 degrees of retard for more than 10 seconds, it throws a P1320.

The tech wasn't sure what was causing this so he called Mitsu central intelligence (?) and they were aware of the issue. It's a false CEL and a known problem. They will be shipping a re-flash in mid April to fix it. It seems to get triggered when you turn the key on but don't start the vehicle or some sequence of ignition key events.

As for the erratic idle issue, I haven't seen that for a couple of days and the tech said Mitsu hadn't heard of it and didn't think it was related to the P1320.
