I'm having a sruddering problem while sitting at ideal....

Misfire is usual culprit for engine shudder, it can feel worse if you have a broken or weak engine mount. Most misfires will leave a trouble code, so check if you had any set. If not, check mounts. If i'm not mistaken your car has an engine dampener as one of the engine mounts, look that part up and check if yours is ok.

I did have a radome misfire code on my car but I clean the connections at the coils and the coDE went off which was good cause I don't know how to tell which coil is bad so I'd just change them all????? Any more help???

Did the code clear or are you still getting misfires? Injectors and plugs/wires can also cause misfires, should also check or clean maf sensor.

No code turned itself off now..... and where's the mad sensor and if u know ws maf?
