I have a 97 T/A WS6. My friend has a 97 Z28. Both of our cars have the same LT1 but his car has 2 plugs on his coil and he swears thats what im suppose to have on my car. From what I have gathered I have the correct one plug type coil for my car. Who has the right coil? Me or him?

 

The single connector coil was introduced on the f-body in 1996, so your 1997 should have one. Two connector coils ended with the 1995 model year.

 

I knew I was right about my one plug coil. The intriging thing is how in the world did he get a 97 with a 2 plug coil? All the wireing looks stock so I don't think he would have gone thru all that trouble just for that. I have to get to the bottom of this.

 

Someone blew his motor and swapped a 95 or earlier motor/harness in. Look and see if he has rear O2's in it.

 

Good point. I'll check that. Why would anyone go through all that trouble is bewond me though. There is so much crap to change. Y Pipe wireing harness maybe.

 

Engine fire maybe? or someone didnt know how to make a 97 wireing harness to work on a 95 motor?

I am sure their is a million reasons
