I have a 2004 Chevy Trailblazer.I drove home from NY to NH during this last snowstorm. I made it home without any problems, and I stopped somewhere for a little bit. My gas gauge read it was low but the light never came on to tell me I needed gas. When I left where I was, my truck died shortly up the road, and I immediately thought I ran out of gas. I did get some gas, and it started, but after it was running really rough, and the service engine soon light came on and started flashing at me. When I first ran out of gas I tried to start it a few times because the gauge didn't say I needed gas yet. I just had the fuel pump changed a couple days prior because of the common gas leak problem. The truck does start fine, and it drives with no hesitation to power from the engine. The transmission is shifting fine. The vehicle is shaking in idle, and it is making a lot of engine noise. The change oil light was also on, and I changed the oil yesterday. I had the exhaust manifold repaired back in September when I bought it. Can anyone determine what may have happened, or the possible cause of the problem?
When the Check Engine light flashes it means there is a significant emissions problem detected and it needs to be fixed very soon. Continuing to drive with this condition will destroy the catalytic converter. You may have gotten debris in one or more of the injectors when the gas got low.
The first thing to do is get the codes read and find out what the computer is reporting bad.

Had a 94 Olds Bravada that did a similar thing and it was EGR valve on the front of the intake. It' s easy to take off and clean with WD 40 and if you have an air compressor blow it out good.

It sounds like u got a coil pack going out. Alot of times when your engine is cold or when you arn't putting a load on it the coils won't fail. How ever when the engine reaches operating temperatures and there is load on the coils that is when they are going to break down. my advice would be to get a scanner and see what cylinder the missfire is at then swwap that coil to another cylinder to verify that the coil is defective. If it is purchase another with a new spark plug put it in and let it rip.

You need to check the fuel pressure to the TBI. I just fought one which was doing the same thing. I pulled the fuel tank to replace the fuel pump. It turned out to be the short hose from the fuel pump to the steel line coming out of the tank. It had a split in it so I wasn't getting enough fuel pressure. Some places show two pumps available. One you can pull the unit and replace just the pump. The other the pump and sender are all one unit. Hopefully you have the first one. The second is around $300.
The easiest way to get to the top of the tank is to pull the front 6 bolts mounting the bed and loosen the back two. Take the three screws from the filler neck and unhook the rear axle vent tube. You can then take an engine hoist and lift the front of the box. You can get right to the pump and gauge assemble in the top of the tank. Most times, this works easier than emptying the fuel tank and removing it.
