S10 Blazer runs very rough at idle
This is a 4.3 CPI W series
I was driving on highway when engine light came on, took exit, upon stopping very rough idle, terrible exhaust fumes, no smoke, poor brake pedal.
Used Seafoam with fillup gas, ran w/no changes. This engine has run flawlessly til now. Fuel? Spark? Most likely?
