How much should it cost to replace the spark plugs on a 2004 Lincoln Aviator?

Vehicle diagnosis was that bad plugs were the reason for misfiring on 3 cylinders. Vehicle has 41000 miles on plugs. Quoate from dealer was almost $350 to replace plugs?? Seems high for eight $6.00 spark plugs unless I am missing something??

I am skeptical about the spark plug diagnosis. 41K is too soon to have no less that 3 plugs fail. If they are merely going by three different P030X (X would be the number of the cylinder misfiring) code to condemn plugs, they are not doing their job. If they use a scope to measure primary and secondary voltages, then they'd know 100% that it's plugs

I hope you didnt have to pay for that diagnosis, because I am fairly sure it is wrong. This code means more than simply bad plugs.

Possible causes for P030X codes:

Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

There is also a TSB (technical service bulletin) out on 04 Aviators for vehicles with those misfire codes. Have the dealer check for:

TSB No.: 06513
NHTSA No.: 10019912
TSB Date: January 1, 2006
Failing Component:
Engine And Engine Cooling:Engine
Description of Summary:
Engine misfire with diagnostic trouble code (dtc) pewee, p0302, p0303, p0304, p0305, p0306, p0307, p0308, and p0316.

If they wont, then go to another dealer.

Hope this helps

they charge by the hour labor rate is high just check with another garage and get another estimate but you should be concerned about why the plugs are bad they are 100,000 mile plugs so they shouldn't be bad. and the warranty is still on the vehicle so you need to say to the dealership hey there is something wrong if this vehicle needs plugs because they are 100,000 mile plugs and try to get them replaced under your factory bumper to bumper warranty.

350?!?!?!? Spark plugs are 2$ a piece at checker. Replace them your self, its easy.

They must have wanted to change the plugs, wires cap and rotor.. and something else. that still doesnt seem worth 350$.. at all...
