fuel injector problems

[discodancepant]

I had my 99 yukon (5.7 v8) serviced by jiffy lube, just for oil change at first. They asked if I would like my fuel injectors cleaned. I said sure. Little did I know that this procedure had caused countless other people issues.

That said, I am having issues with inconsistent ignition which I beleive is due to what I said above. My question is how can I verify this is the issue? My next obvious question is, if I do find it to be the source of my problem, can I repair the injectors or do I need to replace my whole spider system?

What type of cleaning did they do? I'm guessing they used an arosol can of cleaner that they ran the car on until it died.? What is happening now? Rough idle , no start, something else?

Probably used a chemical fed into the power brake booster, if executed incorrectly, it will blow out the injector "O" rings.

I would not go to places like "Jiffy Lube" even to use the restroom, their goal is to work on as many cars as possible in a day, and the quality control suffers. Find out how many drain bolts they have stripped on the aluminum oil pans in the last month, they coordinate with a repair facility just to fix their mess ups.
