Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
What is the issue you are experiencing? Is the vehicle Misfiring and running poorly?
Most common thing is what we call the Spider injector assembly. These are fairly common to go bad and the part has been updated. This spider injector assembly sits under the intake. So there is a bit of labor involved to replace it. This can cause the truck to run poorly and misfire making you think it coils and plugs when it's not.
If you have any more questions on this, please feel free to ask.
