128,000+ well-maintained miles and suddenly the engine behaves like it's missing on two cylinders with matching loss of power + gear-stick vibration and "electrical smelling" smoke coming from right hand side of engine towards the rear. Smoke also appeared in passenger compartment, maybe from the air vents...but looked like it was coming from the area of the stick shift housing. Dash instruments not indicating any problem, oil pressure OK, Alternator generating, and temp OK. Shut engine off and had a tow back to home base. Before heading to garage mechanics would appreciate possible causes for the problem. Thanks! Richard Cooper.
