SPUTTERS EVERY MORNING

1999 Chevrolet Blazer • 156,000 miles

I have a 1999 Chevy Blazer and for awhile now, every morning when I go to start it, it sputters and misses until I start driving it for about 20 minutes then it stabilizes and drives fine. What is causing this?

Seems like the cold start system is not working correctly. Are there any trouble codes?

There are no trouble codes. Only thing that comes on is the service engine soon light, after a couple of days it goes away. Something else to add, I especially have a hard time when it rains the night before, but again for about driving around for 20 minutes it clears right up and drives fine.

That indicates trouble codes. Get a scan to check for trouble codes. Most parts stores provides free scanning services.
