Fuel Injectors

[red123]

All.
I have a 1997 Aurora. I think that i have a or some bad fuel injectors. Does anyone have any info on this type of problem. Chenk eng light stay on. When i drive the car the service eng light starts blinking. Auto zone checked it. They gave a code of p0307. Changed plug 7. The one that went with that code. Still bad. The car is shaking really bad too. I wonder has anybody eles seen this type of problem if so pleased let me know.

Did you check the coil pack for spark plug #7? It may not be getting the voltage to fire. Just a thought!

I would go and replace all of the plugs and wires and maybe if you think it is a fuel injecter problem add a can of seafoam to a full tank of gas it might help clear them out. When you say the car is shaking do you mean like allot of abnormal engine vibration or what?

Thank you all who replyed. I'm glad to tell you that the problem is fixed. It was the fuel injectors. I had what called a motor vac and it cleaned the injectors as well as all the major parts of the motor. It's runs and sound like new again. Only cost me 100.00 bucks. I'm very happy right now.

I also have a 97 Aurora and it is experiencing the same problem with misfiring and Service Engine light is either on or blinking. The mechanic shows 2 plugs misfiring. He suggests a full tuneup and the Motovac fuel injection cleaning. Given your experience, I will try the fuel injection first before doing the full tuneup.

Any other thoughts.
