Default dealer ripping me off????

I have a 2004 MPV V6. It developed a misfire on the highway and we had it towed to the dealer. They tell us it has a bad coil and needs a replacement. No problem there. Here are the problems:
They tell me the intake needs to come off to replace a coil. That true?
They tell me that I really need to replace all three coils on that side because the labor is to high to take off the intake(about $220). Is that really necessary?
They also are trying to sell me a $150 fuel injection system cleaner.

I am thinking do one coil and skip the injection cleaner, which reduces the bill from $530 to $260.

Default Check the PCV hose

I had similar isssues and had those coils changed. Yes it is long but if you are going to replace one might as well have them all replaced. But before you do check the PCV hose. To replace it its a DIY project.

I am convinced that the PCV hose was going bad for a while and caused the random misfire codes. I think the dealers are jsut repairing items that do not need to be replaced and ultimately they end up replacing the PCV hose anyway.

Best thing to do get an OBD code reader. It pays for itself in no time.
