Random Misfire 0300: Dealership reflash available...
man, i feel for you guys. glad i did the lemon law buy back. i knew mitsu wouldn't be able to figure this one out. if you guys do the buy back in a timely manner you can get get close to 100% of your money back. good luck!

My car is approaching the 1 year old mark. I have not had my CEL go off since the reflash but I am still wondering if it's going to happen again. So many people are still getting the problem I want to make sure that I have all options open to me should the problem show up again.
well, just wondering. I might be selling my truck in the next couple of days. if so I planed on buying an evo. Should this be something that would make me look towards another car. I really want the evo more then anything. I've been looking into this car since december, but I decided to buy an truck instead((work related. I do constuction as of right now but I'm changing jobs and want need my truck anymore.)) I remember reading one person's post of have aem ems and don't have to worry about it. just wondering if this is just a random thing and if I test drive the car what condition I should put the car in to try to reproduce the problem, if it's there. thanks for you help. hopefully I'll be a new owner of an 03 A.S. Evo8.

how does the buyback work? Just in case. I have had my car in the shop about eight times since the reflash was available. I have been waiting patiently since I brought it to the dealers attention. It doesn't work and they can't figure it out. I'm getting irritated since I commute to work about 44 miles one way and it always goes off. Irritating!
Not that I wish ill will upon anyone, but I hope this problem becomes a 100% model wide issue so that POS Mitsu will get off their asses and take some real action, half-assed ecu reflashes non-inclusive.
I was told by one of the technicians (reliability??) that the reflash was an "idle P0300 fix". How many people are throwing codes at idle?? Not very many I would think. Hmmmm....looks like they spent all that time creating a fix for something that was not a model wide problem. Probably specifically pertaining to mods on peoples cars?? Nice Mitsu....good work! :/
I have been reading the threads for numerous weeks now, and believe that it is established that this random missfire is a serious problem. My first misfire code was thrown at just under 1900 miles, the second about 100 miles later, the third not 250 beyond that. The fourth just was thrown. I understand that it is supposedly a random misfire situation, but I just want to run something by you all, especially webguy330i. I just sold my BMW 3 series to get into this evo and the evo is probably the jerkiest car under light throttle high rpm situations. My car bucks and whips wildly. Do all cars drive like this? I have only driven my own evo. Is this simply the nature of high stress, turbo'd cars? I could hold my 3er on perfect angle when drifting at light throttle, adjusting the rear end angle with my right foot. If I try anything but full throttle in my Evo, the thing just bucks and jerks crazy like!?! Is this just the nature of the car? Can tuning solve some of these problems? Or do I just have a lemon x 10?
To all-
I just dropped off my 04 Evo RS at the dealership, they really don't know s***. The tech told me he would put it on the scope and see what the issue was, I told him, that it had already been relfashed...oh well. I figure I am just going thru the proper steps preceeding a buyback. I will keep you informed of the car's progress.

So I am now driving a Hyundai Elantra "Vehicle o' Fury" as a loaner. Veracom Mitsu has my car in their possession and I told them to keep it until it gets fixed. We'll see what they turn up by the end of the day. They have a technician (who incidentally has '23' years of total experience... and is heavily bolstered as their best tech by my service advisor there) who will be working on my car and working with tech line to figure this out. We'll see won't we?
I can't wait for them to try to blame it on one of the following mods (I am happy to list them since none have an impact on this problem):
- HKS turbo timer with intermediate ignition harness (no issues)
- Buschur 3" turboback w/ high-flow Catco cat (no o2 sensor issues/cels)
- HKS RS intake (no issues)
- Forge MS D/V (no issues)
- Grounding kit (lol)
More to come as I am updated folks.
Hey 32e-
I am glad you dropped your car off as well. We should get our two dealerships in touch with one another so they can be confused about this problem all together.
I have the same problem whereby my dealership seems to know nothing of this issue, and they continue to tell me "well if it's being caused by your modifications we're going to have to charge you for the diagnosis time" blah blah.
I already know it's not because of the god damned modifications and you do also!!
Luckily they did assure me that they are also of the inclination that the mods are not causing this and that they are quite sure that Mitsu will foot the bill regardless. They have my 'file' and are aware of all my Mitsu warranty issues, so I don't think they want to step on my toes anymore than Mitsu already has.
To answer your question about the throttle 'jerkiness', your bimmer was what year? If it was an e46 it had drive-by-wire, an electronic throttle system. It also had the floor-mounted (as opposed to hanging) gas pedal. The more important part is the DBW, which uses a magnetic plunger setup in the pedal assembly to send a signal to the ecu to modulate the throttle accordingly. This is why your car never seemed jerky. My 330 had nothing but smoothness (except for the fact that we had the model-wide 'sticky pedal' issue, whole nother story on that). Almost all manual-trans cars without some sort of a DBW-variant will be jerky in 1st/2nd gears at very low rpms. The torque multiplication of these gears and the engine's inability to control itself (via the ecu) to prevent stalling/etc. is what leads to that issue.
Did you ever notice with your bimmer that you could get the car rolling very slowly in 1st (even 2nd) and then proceed to let off the gas and have the car 'drive' itself? I went all the way through to 4th gear without ever touching the gas and hit 25mph.
OK, O/T post is over.
Back to the p0300, this **** better get resolved! This is my final trip to the dealership. Go Hyundai go!

Webguy-
I have had several Bimmers over the years, I currently have an E30 track prepped 318is, but the last 3 was a 2000 E46 323ci Coupe Manual. It was ultra smooth, and I never had the unintended acceleration that plagued so many Audis of the 80s and 90 and seems to plague yours. But yeah, regarding the Evo-
I dropped mine off at King Mitsubishi in Fort Lauderdale, FL. I just called to get an update on the car. On the scope it threw the...anyone, anyone?...0300 random misfire code. They too have a call into Mitsu's tech support line...i.e. no idea what they are doing or what to do...As per standard, I will keep you posted...BTW in case Mitsu gives you ANY prob about your mods...my car is dead STOCK!
32E ?2?==>?
haha...OUT!

Hey bro, yeah I wouldn't be surprised either if they came back and said something stupid like "well we'll replace your injectors" or "you need a new ECU" or worse yet, "Oh well it looks like we have to replace your entire turbo system, HUGE job, etc. yadda yadda etc.".
I know a lot of these people are having this issue stock so it's not too much of a concern of mine that they will void me based on mods, but they do love to throw the 'race card' of mods if you will.
Regarding your bimmer, since it was an early e46 (323) you actually DIDN'T have DBW! So I am not sure if it was just the pedal config or perhaps the fact that it's an inline-6 with lots of low-end torque to keep itself 'propelled', or if it was just setup that way in terms of the ECU from BMW.
I can tell you that the 'sticky pedal' issue I told you about above, was addressed within 6 months from BMWAG/BMWNA and actually issued as a 'recall'. The pedal just got a little notchy in the heat of the summer which caused an uncomfortable driving situation. Basically it was nothing major like this p0300 issue and BMW went as far as to come on the forums and post about it, being proactive about contacting customers, etc. etc. Imagine that?!?
I would **** my pants if a Mitsu rep actually got on this forum and attempted to help anyone with their issues.

It is very impressive that BMW was on the forums to proactively help customers. The tech at King Mitsu said "well I don't know about all those forums, but I can get on the phone with Mitsu support." haha, wut a joke...
I too would be very surprised if Mitsu got on to help solve these probs. Anyway...I have to go get a pickup from Enterprise...love them trucks!

BMW is an entirely different level of customer service. I guess it comes with the price of the cars. :P Regardless, I was spoiled and now I am realizing what 'real' auto customer service is all about! Gotta love it. Enjoy the Colorado or whatever they give you.
