Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Why on earth would changing spark plugs cost $371? Can you scan that receipt, post it and show it to me?
Is this the 3.6l? I see total labor time for all 6 spark plugs is only like 1 hour. At an average of $75 an hour, plus the price of the spark plugs that should be no more than $75 plus maybe at $5 a plug, like $30. that's only $105. Why is the bill so high?
Is the check engine light on? Did Pep Boys retrieve any computer codes? If so which?
Ok, so what is your question?
You opening post never contained a question, although your second post said, "Sure but how about my question".
I assume you have a question about how to diagnose and repair the engine shuddering or studdering. I would try a new fuel filter and if that don't fix it, check he fuel pressure.
The fuel system pressure for the 3.6l should be 58 psi ± 5 psi.
