2000 blazer runs rough and surges


Faulty idle air control valve or timing chain has jumped. So after you changed plugs it got worse? Better double check to see if the wires are right. You should also look for more damaged loose or cracked vacuum lines. Wiggle them all around with the engine running.

2000 blazer runs rough after gas tank was overfilled


there is a vapour purge line from the tank to a charcoal cannister. The line& cannister has been contaminated with liquid gas. When the engine attempts a normal purge from cannister it gets loaded with raw gas, causing rough running and cherck engine light. Replace cannister. Never over fill gas tank, especially on hot sunny days
