Hi, it started with the engine stalling while driving on the freeway. Now the engine starts to stall randomly after I drive for about 5 minutes. Sometimes the engine stops while driving with a big rattle that sounds like an old diesel engine. In idle the engine now kind of surges.
Anyone ever experienced the engine dying on you with a loud rattle?

Re: engine stalls with a big rattle
None of the sensors would keep the car from running. The rattle has me puzzled, but i think it might be an ignition problem. To check for spark, remove the wire from one of the plugs or the wire from the coil going to the tistributor, and using insulated pliers, hold it near metal while someone else cranks the engine.
