04 coupe 90k - Started rough & smoking...Help

[SVTCOBRA]

Started rough & was smoking then shut down.
Turned over 4 or 5 times but would not stay running.
Then, finally stayed running and running smooth.....
No SES light or anything. Did not drive it cause didn't have time to.

The only thing I did to it yesterday was wash the car.
Rinse the engine off, then cleaned out the air filter box and replace the air filter.

Any ideas??
Going to try again today & see how it behaves.

Probably got water somewhere it shouldn't have. But must have dried out now.

I'm hoping that's the case....at the time, I had had a beer(s), so didn't want to go out and test it....was just moving it over so we could play cornhole in the driveway. Family gathering for Mother's Day.
Decided to work from home so that I could check it out today.....instead on the HW at 6AM.

I assume you check your oil frequently?

yep, it fired up fine every time today. Thinking something might have gotten wet.

Water for sure man...can't do that on modern vehicles anymore. Get the codes checked to see what is toast.

Well, I made it into CLT today, so keeping my fingers crossed that I get back home!!
Only difference this time when washing the engine is that I did not stuff grocery bags in the intake to keep the filter from getting wet by indirect spray because I was going to replace the filter once I was done. Maybe that was my mistake cause I've washed the engines in all of my cars numerous times over the years.

I normally spray Castoral Super Clean all over the engine and bay, let it sit, and gently hose off with spayer on shower setting.
Been doing the G's like this since our first one in 2005......hate working on a dirty engine!!!

So is she good now?

[SVTCOBRA]

Yes! Thanks!!
Thinking some water went down the wrong way....
Other than the airbag light coming on (reset and is off now), the gas door sticking, the driver door not locking....she's good!!

[biggie]

Driver door just the lock actuator gone out? That was a PitA to do.

or going....works sometimes, other times does not.

I would say might be a partial flooding coupled with the humid weird weather we are working on in this side of country.

It happens from time to time. The smoke and long crank probably are working together.

Best advise I can give you is give the ole G a few miles of spirited driving. High engine load, but not abusive. Once you start to smell it your in the zone. Drive it for several miles to make sure the cats are clear and make sure the injector tips are nice and hot.
As they age they can choke themselves on fuel sometimes accidentally. If it happens only once and a great while you shouldn't need anything major.

Especially in the coupes. I techs who have worked on many cars who do not do these well. It is not something I would advise the DIY'er to do themselves. Lining up that window takes some practice.

[SVTCOBRA]

Oh crap! Sounds like a pita!!!
Remember resetting windows in my 69 mach.....also putting on new (fresh from the junk yard) door hinges by myself!
Maybe I can talk Biggie into heading south for some BBQ and range time in exchange for help!! But, for now my key works old school style.....
