My wife has a 2001 Chevy Impala LS 3.8L and the car ran great until recently that is. Doesn't matter if its early in the morning, after a short trip or long trip. The vehicle is very hard to start and this is not all the time, sometimes the vehicle starts on the first try and runs great but other times we sit for at least half an hour trying to get the vehicle stated. It tries to start but runs very rough and sputters out. Sometimes while driving under normal conditions 35-45 mph the vehicle just kills for no reason and is very hard to get started again. I recently changed the fuel pressure regulator but the problem persists. No codes come up on the computer and I hate to get rid of this car because of something simple. Help this frustrated chevy owner. Had tune-up and fuel system cleansed!

I will need some info to better help you so bare with me here ok. When was the last time you replaced the fuel filter? Has it had a recent tuneup? Do you know if you have spark and or fuel when this happens? Get back to me with what you can and we will go from there ok.

I changed the Fuel filter, fuel pressure regulator and air filter a month ago. The tuneup, EGR valve and fuel system cleaning was done at 105,000 miles. I never checked to see for fuel or spark when this happens!

Ok we need to find out if there is spark or fuel missing when this happens until we know that we can guess this thing all day. Let me know what you find and we will go from there.
