Question about GMC Sierra 1500
I put $20.00 in gas an put a bottle of injection cleaner in the tank and then after about 25 miles it started running really rough and the check engine light came on. What can I do to fix my problem?
Put more than 3 gallons of gas in your tank- $20 = 3.5 gallons here. The bottle of cleaner specifies how many gallons of fuel is to be mixed with the cleaner. Usually 8-10 gallons for the small bottle cleaners. Whatever. Follow the directions. It will likely run like garbage for about a quarter tanks worth, but should clear up eventually, UNLESS - there was something wrong before you put the cleaner in. Have you put cleaner in before now? If not, why did you decide to do it now? If there was an issue before, that issue needs to be cleared up before trying additives, unless you are absolutey sure you have a dirty injector or two. Also might help to buy the highest octane rated gas you can for a tank or two. The more expensive brands (Shell, Exxon, Mobil, etc.) usually have some detergents in their gasolines that help clean injectors on their own too.

SOURCE: check engine light need help
Your Air/Fuel Ratio sensor is failing. It is also called the Bank One sensor. The sensor itself is about $200 from a parts distributor and somewhat more than that at a Lexus parts department. Labor to remove the old sensor and replace it with the new one will also run you several hundred dollars.
If you're mechanically inclined, you can tackle this repair yourself. But you must first determine the exact location of the failed sensor. And be careful not to strip the threads in the manifold when you remove the old sensor.
Let me know if this helps and please rate this solution. lone99star

You could be running to high of an octain for fuel. Try running your car with the sugested fuel rating and see if that works. Sorry there is not enough information with your problem. Good luck

fuel pump is burned out from running out of gas, the pump is cooled by the gas it sits in inside the fuel tank, when you run low on fuel or out of gas you over heat the pump severely and the bearings in the pump seize up, have seen it dozens of times in my 30 years of dealer work.

It wouldn't hurt to change the filter, but it sounds like you got a bad batch of gas, if it was running good before you got gas.
Get a bottle of dry gas and put it in the tank, if there is any water in the gas, that will clear it out, also it wouldn't hurt to put a bottle of fuel injector cleaner in the tank, I use that stuff all the time to keep the fuel system clean.
