Describe your 1995 Chevrolet Blazer Probl1994 CHEVROLET 5.7L BLAZER RUNNING ROUGH AND WONT IDLEem
First thing, check for vacuum leaks. Wiggle all hoses while engine is running and listen for a hiss. Check all intake bolts for tightness. Dump some soapy water along the edge of the intake where it joins to the head. If it bubbles a lot, your intake gaskets need replacing. Change plugs, wires. Change cap and rotor. Change fuel filter. Do that much and get back to me if no change.
