The bracket on top of the strut tower can just be loosened so it will move out of the way. The dipstick tube will move aside slightly without taking it out. The cover on the left side will come out by pulling it forward and up. It looks more difficult than it is. The COPs are held in place with one screw and the electrical clip. Compared to replacing the valve cover gaskets, removal of the COP covers is a piece of cake.

Replying to: rgnmstr (Nov 17, 2008 6:21 pm) The first time I had a misfire, I had the dealer do a stress test and he found one bad coil. They participated in an After Warranty Adjustment on that one. Later I had another one go bad so I decided to change the remaining seven myself. I had already changed the plugs once so I knew what I was getting into but had no way to figure out which coil was actually the culprit. Eventually, they all seem to fail anyway. An independent shop might not be too spendy. I don't know what the flat rate manual would say in terms of the time needed for labor but I doubt if it would be more that a couple of hours - just a guess.

| I was sitting on some ice and couldn't move because of the rear wheel drive so I reved the engine probably more than I should have, but after I freed myself, the rpms were high and at idle it's kinda rough. It feels like it's misfireing too at higher speeds. Hope I didn't mess up the transmission. I just had my ignition coils replaced a month ago. Last week it was in for a rear brake problem. I'm a non-mechanical woman so any help would be helpful before I take it in on Monday. | |
