Service engine soon light comes on after 2 to 4 miles of driving. Turn the engine off, and does same after starting again.
Does the analyzer have to be connected while the engine is not running? If so, is there a way around it?
94 Blazer S-10, Vortec 4.3L, automatic transmission. Observable symptoms are poor gas mileage 13-15mpg, sluggish transmission shifts that seem delayed after driving more than a few minutes. Engine doesn't use, burn or leak oil. No tranny fluid use, color changes, or burning. AC works for about ten minutes then quits (son-in-law says it the low pressure sensor).
