I bought some throttle bottle cleaner, and plan to take it off and give it a good clean this week. The cone air filter was cleaned a few months ago.

I garage my car so the cold weather is rarely an issue, but when I leave my car outside all night in the 20-30 degree F weather, it can be difficult to start. However, there has been once or twice where it is in the 40-50 degree garage and difficult to start. This happens once every 3-4 weeks.

When I have issues, it will start, but run very rough at about 250rpm for a few seconds. I try to give it gas, and half of the time it will rev up and come to life (1500 rpm then settles to 1000), other times it will die.

When it dies is when I get nervous, it will crank very quickly, but not start. I try to give it gas too. Then after 4-5 tries, it will fire up and I see a bunch of white smoke behind me.

Do you think the best thing to do right now is clean the TB, get a new fuel filter, and get new spark plugs for safe measure? I got the car used with 80k miles, it now has 93k.. no idea when these were last changed, I got it from the dealer.

Anyone had a similar issues? Thanks

 

Sounds like a issue with your fuel pump...

 

What supercharger? Change the plugs for sure. You need colder than stock

 

If you start the car, it runs rich....thus if you pull it into the garage from the driveway, the next time you start it, it will have white smoke (gas). Blue smoke is oil...I would check fuel pressure on the rail.
