    Posted: September/09/09 at 12:58am
Now that the weather is colder, the Mini dies if i dont let it warm up for 5 min. It just seems to really bog down and if i press the gas it doesnt respond. it kinda gurgles and then will rev. but its died everyday this week even when i press the gas. Once the car is warm however there is no problem whatsoever.This is a problem that has started to occur after Jan's tune. Wasn't so much of a problem when the weather was warmer. But i drive to class and waking up 5 min earlier to warm up my car is really draining me Sleepy

Has anyone had a problem with this? I talked to Jan about getting the remote tune to try to figure it out, but he has been pretty busy so I figured I would ask before bothering him again.

That sucks. I am fine. When you did everything did you do the plugs?

I haven't had any problems like that.  It's still warm over here however, so we'll see if anything changes when the weather turns colder...
One good turn deserves another...and another...

yes, but you will have to either make a new gasket or get some sealant like Permatex

This is what i got.... a piece of crap. The guy told me it was in working condition and wouldnt find any problems with it.

Just called him and demanded a refund. Got a refund and now this is going into the trash.

I had my car tuned last June and saw no driveability issues over the winter.

Rocks in the OCC? That's a new one. Usually steel wool or chain is used to catch vapors. Glad you got your money back.

I agree with John, once it's cleaned out, it should be usable. Unless there's something else wrong with it.

well you can kinda see, but there is rust on the entire inside of this thing. I doubt it can even be cleaned without power tools.

I can clean it up for you if you want.

By chance the rocks weren't BB's

Since you have an OCC, your's must be a S/C model.  There is a long history of starting problems with the older cars as the weather starts changing.  Often it corresponds to the change in gas formula.  Outside waiting it out (it will eventually get better if this is the problem), the recommended fix is to run a tank of regular through it and let it readjust to everything.

Rob, i've heard this but never really understood why it would work.

haha John, I wish you could have seen how much rock came out of the OCC. Its unbelievable. The guy must have filled it with rocks and dirt and the thing might have rusted completely. I wont throw it away, i'll try to take it apart and see if i can sand the rust down.

I am still tring to figure the rock thing out, must be special rock. That canister should be aluminum and should not be rusted just stained real bad. If you need it polished back up just let me know, I would be happy to do it for you.

I used to have that problem too with my 2005 cooper but have never experienced it now with my 2008.  Of course my 2008 lives in the garage when my 2005 had to live outside!  But at the time, when I complained of it to NW Mini they gave me a spiel about the gas and how it changes.  That's when they told me to use a mid-grade gas.  But I don't recall it made any difference.

Hmm interesting. Looks like I will be trying some regular gas out to see if this fixes any of my problems.

John, not special rock. Im talking about rocks you would find in your back yard. There is definitely rust in there.

Lololololol , I am sure there is rust just should not be any rust on the canister that is mostly just stained . I would say use carb cleaner but it might take the paint off.

Be careful with regular gas being that your car doesn't have a stock tune. Maybe a call to Jan is in order to find out what the issue is and what can be done to fix it. A bandaid solution, especially since you're running more timing than stock, might not be the way to go. I don't know if the ECU will be able to pull enough timing to prevent knock. Maybe it might but I'd check first to be sure.

John, you mean if he takes it easy, the ECU will relearn? Perhaps but I'm not sure. My reasoning is that since the ECU parameters were changed, will it be able to learn enough? I'd hate to have him find out the hard way. Jan would know for sure.

Jacob, what brand of gas are you using?

Here is some fun reading while you wait to here from Jan. http://www.northamericanmotoring.com/forums/stock-problems-issues/44204-is-your-car-stalling-upon-starting.html

Larry did we ever deside when you have to up grade the fuel pump? Is that after 240hp?

BTW around page 10-11 they start getting into changing fuels.

Good question. I have yet to come across anyone that has upgraded the fuel pump. Even the people with stroker motors and heads haven't mentioned it. They run bigger injectors so perhaps the stock pump has yet to be maxxed out. I'll let you know once I pass 240hp. Wink

That won't affect starting anyway. 

Running a tank of "regular" through there is not a bad idea (keep a bottle of octane booster handy if you're worried about pinging).  It stopped a sagging issue I had waaay back when my Mini was stock...
One good turn deserves another...and another...
