    If you mean the coil pack, yes. Remove 4 mounting bolts, then 4 electrical connectors (2 on each side). Then just move the coil pack out of the way.

    What DTC's are you getting? Clearing them may not help. If they are current they'll just return.

    You'll find the DTC definitions here.
    http://myweb.accessus.net/~090/dtcobd2.html

    After the DTC's have been displayed, use the HIGH FAN button to answer YES to the prompts and the LOW FAN button to answer no til you get to CLEAR CODES?

    Re: 97 deville-changing plugs and wires

    Here are the 'descriptions' for the codes (up to you to figure out why they are happening)
    P0300 - Engine Misfire Detected
    P0603 - Control Module Long Term Memory Reset
    U1096 - Loss of Communications with IPC
    U1064 - Loss of Communications with DIM
    B1771 - Cassette tape slow
    B1312 - High Side Temp Sensor Open Circuit

    If it were me, I'd clear all the codes for all the modules and then shut the car off and restart and check codes again. History mean just that, they happend in a prior driving cycle. Current means the fault is currently present. Almost looks like someone had disconnected some wiring with the battery still connected but then plugged it back in? With the Two network codes (U1096 & U1064) Loss of comm with IPC (Instument Panel Cluster) and DIM (Dash Intergration Module), not sure about the B1771 (Never used my tape player, just listen to CDs or the radio), the B1312 has something to do with the AC system, the P0603 means the battery went dead or was disconnected and P0300 could be as simple as previously having bad gas (in the tank not from food ) Hope this is a little help, I'm far from an expert!
