Alright, just yesterday my Blazer started acting funny on start up. Doesn't want to keep running and the idle seems really low. Specs: 90 TBI stock. If I rev it on start-up it will eventually stay running. I would guess clogged injectors, but the weather just changed the day it started acting funny. Cold and rainy. Could this be water or temp change? Any guesses? K-5...Soccer moms inquire within.
