GreenCactus Posted January 10, 2016 Report Share Posted January 10, 2016 Cricket has been having some issues lately. She won't start the first few tries, then the idle is really rough. It evens out in a couple of minutes. The check engine light comes on and the code shows misfires. We've replaced the spark plugs and the coils. She ran fine all week, until this morning. Same issue and same codes saying misfires (cylinders 1, 3 and random). Any thoughts? I really hate to take her to the dealership. Link to comment Share on other sites More sharing options...

CarlB Posted January 11, 2016 Report Share Posted January 11, 2016 Check the ignition wires. Look for traces of gray. That will tell you the spark is jumping. The best places to look are anywhere the cables touch. A black spot with gray around it is a problem. If it misfires while idling look under the hood at night and you can often see the spark jumping.

1975_mini Posted January 12, 2016 Report Share Posted January 12, 2016 Laura, Sounds a lot like what was going on with Ebony, it ended up being carbon buildup. Had the walnut blast done, and it was night and day difference. Unfortunately not a DIY or cheap fix. 1975 Mini 1000, 998cc A+ w/ K&N air filter, 10" Mamba wheels Link to comment Share on other sites More sharing options...
GreenCactus Posted January 12, 2016 Author Report Share Posted January 12, 2016 I appreciate everyone's input! I have an appointment at Ptuning on Monday. I'm hoping it's something as simple as the carbon buildup. While it may not be a cheap fix, at least nothing is "broken". Link to comment Share on other sites More sharing options...
CarlB Posted January 12, 2016 Report Share Posted January 12, 2016 You do not need to do the walnut blasting to clean carbon anymore. CRC has a product that cleans the carbon of the back of the valves. It isn't easy to use on a direct injection engine because you need to introduce it into the manifold, but it is much easier than disassembling everything to walnut blast.

That's great to know. I'll be sure to mention it to Ptuning! Link to comment Share on other sites More sharing options...

randmness Posted January 13, 2016 Report Share Posted January 13, 2016 Our cars must be kindred spirits. :laugh: Driving to work this morning...my Service Engine Soon light and check engine light (exclamation in triangle) both came on. The car immediately went into limp mode where I couldn't really accelerate above 50mph. The car also seems to idle weird when in gear. Pulled the codes....P0300 (Misfire.) If I clear the code, it comes back within 1 minute of driving. Spark plugs, coil, and wires were replaced about 2500 miles ago. For now, it is sitting at the local mechanic. Probably won't be seen until Monday. 2006 Mini Cooper S w/ 120K miles 2006 Mini Cooper S Link to comment Share on other sites More sharing options...
FAST060 Posted January 15, 2016 Report Share Posted January 15, 2016 This reminds me of BLUR. It ended up being the gaskets being replaced that brought her back. After all cylinders and coils being replaced.

randmness Posted January 19, 2016 Report Share Posted January 19, 2016 Did you find what wrong with your car? Just got mine back. The supercharger intake tube was broken. The car is alive. 2006 Mini Cooper S Link to comment Share on other sites More sharing options...
GreenCactus Posted January 19, 2016 Author Report Share Posted January 19, 2016 Did you find what wrong with your car? Just got mine back. The supercharger intake tube was broken. The car is alive. Not yet. She's still at Ptuning. They haven't figured it out yet, though they suspect it might be the HPFP. That will really suck, because I'm well out of the warranty. However, assuming it IS the HPFP.... MINI extended the warranty on them to 10years/100k. Cricket has a 128k, but the HPFP was replaced under the original warranty in 2011 at 55k. Is there a case to get MINI to replace it again? I have no confidence in the dealerships anymore. All of the good people have left. Link to comment Share on other sites More sharing options...
JAB 67 Posted January 19, 2016 Report Share Posted January 19, 2016 Randmness: I have heard of supercharger inlet tubes leaking but never 'breaking.' Any idea what caused that? JAB 67 Fairfax, VA 2004 MCS, PW/B Link to comment Share on other sites More sharing options...
randmness Posted January 19, 2016 Report Share Posted January 19, 2016 Randmness: I have heard of supercharger inlet tubes leaking but never 'breaking.' Any idea what caused that? No idea. They replaced it, and the nature of the misfire changed to cylinder 1 & 3. They swapped out the spark plugs, and now the vehicle is driving correctly again. To be honest, I'm not 100% sure if this solved the problem (I pick up the car today.) The spark plugs (in addition to the wires and coil) were replaced less than 2K miles ago. Perhaps, the misfire caused the two plugs to go bad? I'm not really sure. At this point though, I think it may be time to cut my losses and give the car up. 2006 Mini Cooper S Link to comment Share on other sites More sharing options...
Goose Posted January 19, 2016 Report Share Posted January 19, 2016 Just to join in on the misery, my 2011 was in the shop over the weekend as well. Check engine light came on Saturday I limped it to PMoA (glad I was nearby). Oil line leak and coolant issues. I'd rather not say how much it may cost. At least the oil issue has been fixed. I thought the car was running "rough" and I did smell oil burning a time or two last week. Of course I looked under the car to see if I could obviously tell it was leaking. Nope. For now, it's back on the road and running well...but that coolant issue has to be fixed sooner rather than later........:hmpf: On a note more relative to the post, I had my HPFP go at 45K though it wasn't immediate. The check engine light would come on sporadically. Sometimes it would go into limp mode and sometimes it wouldn't. I've also had plugs and coil issues. All my coils were changed at 55K and my plugs were swapped for NGKs at 65K. I have 84K on the vehicle now.
