My 2001 Impala with a 3. 8 v-6 would not start after golf last Thursday, so I had it towed to a repair shop. The shop put in a new fuel pump, fuel filter, spark plugs and wires. The bill came to $900. I had the same problem various occasions over the next couple weeks and decided to look on the internet. This site popped up when I "searched stalls while driving" because the car started stalling occasionally while driving under just about any condition. I bought a new crankshaft position sensor from car quest installed it myself in less than an hour and haven't had any problems for about a week now. Thanks for the info.
We bought a Chevrolet Impala new in 2001. Within three years we experienced intermittent shutdowns of the car. Several times the auto just quit on expressways, but getting over to the side of the road we would turn the key off and then it would start perfectly. This occurred perhaps 5 times in the following 3-4 years. It was a dangerous situation. Finally we took it in to the dealership where they had it for 5 days finding nothing wrong. We started calling mechanics, contacted general motors executive offices (an amy green) and other sources. Several mechanics informed me to have the crankshaft sensor replaced. I "forced" the dealership to replace it and have not had a problem since. This was a dangerous situation as a shut down at high speeds a scary proposition. With all of gm's current (2014) handling of dangerous situations, we thought it time to comment on this one. Of course all this gm work was at our expense. I foolishly bought a new 2006 chev. Diesel 2500 pickup and had the whole back braking system rust up within 3 years, but that's a different story.
