R50/53 So then, what typically causes cold start bogging / sputtering for the R53?

Alrighty, gonna dive into pulling the head tomorrow. I have a new OEM head gasket, IM & EM gaskets, valve cover & plug tube gaskets on the way and a local machine shop is expecting me to drop off the head Monday morning. They deal with R53 heads on a pretty regular basis so I'm feeling pretty good about it

so I am starting to get something similar to this. since I opened the thread a week ago to take a look, I guess my car say I should have this too. on these colder mornings im getting up here, starting has been interesting, I didn't have this issue over the summer, or last winter. I figured it was the car figuring out the temp outside. when its 60 deg F I don't have this issue, now that its in the 40's this is when im getting it.
but mine will turn over no probs rev to about 1.5k then drop and chug at 500 for about 10 sec, then catch itself and head back to 1100 at 14.9% throttle for warm up, not sure if I throw a code during that since I already have an SES exhaust related. but the car never dies. and during the day I don't have this issue at all.
I was just planning on changing the plugs since I don't think they have ever been changed and figuring out that would help

Alright, got the head to the machine shop today & it looks like all of the exhaust valve guides are pretty shot, so I have to replace those along with all of the valve seals. So, the turn around time and cost for the project just went up pretty substantially.
Not gonna lie, it's getting to be more than I'd anticipated -
Head gasket, IM gasket, EM gasket, head bolts & valve cover gasket set from WMW - 220
Mini Coolant - 24
Mobil1 0w40 - 34
Machine shop labor (resurfacing, valve grinding, valve guide & seal installation, pressure testing, etc.) 260
Valve guides & seals from Mini Mania - 170
I also noticed that the thermostat is not OEM so I'm throwing a new 53 dollar OEM thermostat at it while it's all apart.
So then, my current total in parts & machine shop labor so far is $761. Ouch.

I cant speak for your car but believe it or not mine does better in the cold than in the heat. I am getting the CAM sensor replaced this week ill let you know how it helps

I don't think it's normal to have hard starting issues when the temps are a little cooler......unless there is a problem.

I never noticed this before. There's a sticky thread in the r53 stock section on this.
First post is from 2005!

Here in flyover country I had been using a non-ethanol hi-test gasoline throughout the year.In the fall the stumbling would stop and come spring would pick right up again so I switched to a different brands hi-test containing 10% ethanol. The stumbling stopped immediately. In the spring it was back to the non-ethanol hi-test and have been doing that ever since. Go figure.
