Engine shaking at idle. Multiple misfire code
I have a 2002 S80 and the engine is shaking and bogging down at idle. It doesn't seem to be too much loss of power but when I come to a stop, the engine shakes. The CEL is blinking also and its reading multiple misfire codes. I have changed and gapped new spark plugs at .028 and i have also checked the coils. The coils have all been changed within the last year. The engine is bogging down so much that it's very difficult to notice a change is the engine running when I'm checking the coils. Is there a way to test the coils with a device rather than unplugging them to listen for a change in the engine? Also, what device would i use to do that? I have also cleaned the MAF sensor as well. I dont know too much about cars and i am only going by what i have learned on here and other sites. Does anyone have any suggestions as to what may be the issue? Thanks!
