Only thing I can think of is as I stated earlier check the resitance of the injectors to see if electronicly they're fine. The one I had bad was on the passenger side fuel rail and that side was fairly easy to get off. Good Luck. That is about all I have let me know how it turns out. I hope...

There are two fuel rails and all three injectors have to come out when one in the rail is changed. They can check to make sure the injector is electronically functioning with a resistance test, without having to remove the fuel rail. Depending on the position of the injector they may be able...

Hi sorry it took me so long. If you have not figured out your problem yet, here is what I did. Checked coil by switching with another to see if misfire changed cylinders. Checked wires. Cleaned MAF which is just behind the air intake by the air filter. After that the problem seemed to clear...

Since cleaning the MAF the light has been off and it is running smooth. Thanks.
