coil pack problem?

catera00 · #1 (**permalink**) 03-03-07, 07:14 PM

symptom: idles rough at cold start and has less than perfact accelleration.

I am getting a multiple cylider misfire on #4 and #6.
I found oil in one of the spark plug wells a week ago. I cleaned it out and scheduled for the drivers side valve cover gasket to be replaced. Today I checked again to see how much oil had leaked in there since I cleaned em.
I noticed the coil pac is rusted and has some cracks in the #4 and #6 coils (hope thats the right name) I imagine they are expensive so I dont want to jump the gun and buy them if I dont need them.

How likely is it that this is causing the problem? I know they can have a littl rust and still work so I dont want to jump to conclusions. What do you guys think?

Thanks for your help guys!

Here are some pics of my drivers side coil pac:

just spoke with the dealer. The coil pack is bad. Its gonna be $250 to 2 fix it. Not bad since its $215-$225 from an auto parts store. So heres my question, why is the passenger side coil $164 and the drivers side $225? (Advance Auto Parts) Other parts stores seem to be the same. The drivers side is always more expensive. Why is that? The look the same to me

God knows why, its only the moulding thats different....

Price is reasonable as we pay about £170 per pair .....(just over $300)

Have you ever pressure washed the engine?

Why do you ask about pressure washing?

no I havent but I just bought the car from a car lot 3 weeks ago.
I know the valve cover used to leak. Maybe the moisture from that caused the rusting?

I can get coils in Michigan for $100.00, either side.

rock auto has these and it shows the different cars it will fit. Rock auto says the 99-01 catera coil pack will also fit the 03-04 cts. Is this correct? If so gm parts direct sells the cts packs for about $65 per side. On the flip side the ones for the catera are over $100.
