Hi & thanks for reading this!!
I've been have a few issues with my Impala (codes for EGR, MAF, coolant temp sensor and small evaporator leak). After finding one pretty big vac leak, I was searching for more.. and discovered a cracked coil pack..... Aside from the logical (connect the right *.p. to the new c.p. / same location I remove it from), are there things I need to do first? Haynes manual is pretty obscure about much of this, and since it covers several Chevy models, am I to assume that my 3.8 is the same across the board on the other models? A video I found online for another gm 3800 motor said to turn off the lockout, and to disconnect the battery. Am I on the right track? Thanks in advance
