Cold Start + videos
Car: 04 AP2 55k miles
Basically every morning or whenever i leave the car for a few hours my car either cranks slow/takes a couple tries to start/or struggles to get into idle rpms. This cant be normal. Spark plugs are changed and autozone claims that my battery and alternator is running fine when i had it checked. I'm assuming it could be the starter but i wanna make sure i can rule out any other possibilities.
I have a few of my own videos below but here's a random video i found on youtube with the exact same problem.

I'm not pressing on the gas pedal and i am giving it a few seconds before i press the start button
Edit:
Here's a better quality video. Excuse the music at the end, radio turned on.

There are times when it's worse than it is in the videos. Sometime's it takes longer to crank, the stuggling idle lasts a little longer, or it takes 3 tries to start up.

how old is the battery? older battery's are tend to work properly, but when it realy need to deliver power(a cold start) it could slack some.
i would recoomend, swap the battery with a other s2k user to test it a week, otherwise just buy a new one, its never a bad idea to replace a older battery.

Not much help other than to say I have seen it! BTW this is in warm weather, California.

I live in northeastern USA so its getting pretty cold up here now that its October. It's basically an everyday thing when it happens. After that it turns on fine unless i let the car sit there for a few hours until the engine is cold again.

My 2000 AP1 would start like this during the winter season. I took it in to check the fuel pump, and fuel pump regulator, both turned out to be working order. After that I replaced the battery with a yellow top optimum, thinking that my original battery was weak. Still did not get solved. When searching the forums I came across something called a "Learning" ecu. Where the ecu gets confused due to the change in weather. That s2000 was sold. This year I recently bought a 2001 s2000 and it did not have the same problem. I wasn't not fully convinced that it was an ECU problem, perhaps you can reset the ECU and allow the car to "relearn" its conditions. That would be my hypothesis, just speaking from my own research.

A few days ago i tried resetting the ecu but i did it after i got home from work. No luck.. Am i supposed to do it when the car is still cold? I'll probably try again tomorrow.

Bump.
Alright so far the ECU reset doesn't seem to be working. Maybe because up here in Northern US we're getting warm days and freezing nights? The "sputtering 500rpm idle" start seems to be worse on freezing mornings/nights than "cool" mornings/nights.
I don't if this is related at all but, I hear a slight rattle at certain rpms (usually around 2800rpm) when I'm driving. My guess it's coming from the CAT.

Any codes? Before purchasing my car the dealer had to replace the starting module and reflash it due to cold start idling issue. I live in Milwaukee Wisconsin. I believe the code was p1607.
