Hi,

my wife has a 4 Door Automatic Accord year 91 or 92. She had some problems with the way the car was idleing and the way the engine was running. To be more specific the engine vibrates sort of hard while idle at a stop and the gears feel like they change a little slower (or are hesitant) (Made me wonder if the transmission was going). It has about 150,000+ miles on it.

We took it in to her trustworthy shop and they took a look at it. They suggested the following to her (they mentioned nothing about the transmission, by the way the transmission fluid is at the proper level):

Replace Spark Plugs
Replace Spark Plug Wires
Replace Fuel Filter
Replace Valve Cover (My wife wrote gasket on the next line in her notes, so I think I am going to assume she meant Valve Cover Gasket)

All that for a price of $473.53 (How much should work like that cost?)
Also, do you think replacing the following will help the syptoms above?

I also read about the seafoam stuff, I think that would help this problem to, what do you think?

Aren't those parts cheap, and easy to replace. I haven't done this before, but I would think I could replace the spark plugs, the fuel Filter (even though I do not know where that is), and do you guys think it would be possible for me to replace the spark plug wires?

To give you an idea of what I am capable of doing, I have replaced the front driver side headlight unit for the car. That was easy but it is still required me to remove the front bumper, grill, etc. to get to the broken headlight unit and unscrew it out.

thanks
