I bought my car in 2006 and It's had the fuel injectors replaced and the gear shift all in early 2007. In late 2007 I had the air bags fixed too....things were going fine until I woke up this morning and started my car (which I had problems doing) to find the check engine light on. So I got out the book and I read it and decided to leave the car sit for 10 minutes and then try and start it again.No luck still the same problem. Also noticed when I lifted the hood the engine sounds like a helicopter about to take off.It's so bad I can't back the car out of the drive way it sounds like the back end and front of my car is going to fall off. Not only that I also noticed that there is a very bad smell almost like a gas leak but I see no leak....I'm curious if the fuel injectors that were replaced were faulty too...or has this happened to someone else also??? I'm having it towed to the dealership tomorrow since it isn't drivable and I am scared to drive it were with all the shaking...I'm not under warranty any more so I'm really nervous about how much it is going to cost me...I love this car and haven't had any real problems with it other than the recalls...but also very frustrated that things keep happening like this to it.

Hi there: You will have to pinpoint what the engine is missing Spark / Fuel / Compression
three of these are tested when the engine is being cranked over. There
are two way of checking for fuel. Fuel pressure and fuel trigger. Both
are very important and must be present for the engine to start. Fuel
pressure is self explanatory. You just hook up the gage and see what the
reading is. Fuel trigger is check with a noid light. The injector gets
unplugged and the noid light gets plugged in to the injector clip. With
the engine cranking over, this light must blink. This is the signal to
the injectors from the computer. You can have all the fuel pressure in
the world, but it wont matter if the injector is not pulsing gas into
the cylinder like it should.
spark tester, fuel pressure gage and noid light are all accessible at
your local auto store. All three tests play a very important part in
diagnosing a no start condition. Be extremely careful when doing these
Hope this helps; also keep in mind that your feedback is important
and I`ll appreciate your time and consideration if you leave some
testimonial comment about this answer.
These little engines(although very good little engines)have a problem with carbon build up in the intake manifold. It builds up so bad it begins to choke the engine off. The only solution is to remove the intake and soak with a good solvent over night and will generally take you a good couple of hours to clean out to get to "like new" again. Once this is accomplished, it's like driving your car new again!!
Im guessing the miss is very slight being that the check engine light isnt on, I would check with your local GM dealer to see if you have the old style fuel injectors in your vehicle, you will need the VIN.
GM had problems with the early style injectors and they redesigned them, but the only way to know which ones are in your vehicle is to call the dealer. I have had to change these out as early as 80,000 miles. You might be able to have the injectors cleaned professionally, which could help, but if you have the early style injectors i would recommend replacing them if your mileage is average for the age of the vehicle. Once the miss gets bad enough it will pick up a code and trip the engine light. I hope this helps you..
I had the fuel pump recently replaced i just assumed the fuel filter was replaced also cause my fuel pump is in the gas tank. My air filter is clean and I have 4 fuel injectors, no carburetor. A friend of mine who has looked at my car for me says it sounds like there is some kind of air leak but can't figure out where it is coming from?
