Engine Performance problem
2003 Buick Century 6 cyl Two Wheel Drive Automatic 102000 miles
When the engine is cold it runs & accelerates fine. Once the engine is warm it stutters / hesitates at low rpm. The head gasket was recently done & I had to replace the emitions (sp?) Valve because they left it on the manifold. Prior to replacing it I noticed the stuttering. I since have replaced the ignition module & the spark plug wires with little to no improvement. I was about to replace the distributor coils (there are 3) but since it runs fine in the morning before the engine warms up im thinking it's something else.
have the same problem?
