AFTER GEN V SWAP!!! Help

[XtrmGTP]

Guys i have a constant misfire cyl 1 and 5 not as often with loud backfire out exhaust. What should i check? Did not have misfires before swap. My friend did the work who is a GM Master Certified tech so i trust his work lol

Step one: Question work and search for vac leaks, misplaced plug wires, properly connected plug wires etc.

What is the firing order? 99 gtp

 

[matt5112]

6-1-2-3-4-5

Won't do you any good though.

coils are 6/3, 5/2, 1/4.

Doesnt matter which one goes top or bottom as long as its on the right coil.

What do u mean "won't do me any good?" Lol

 

[matt5112]

The firing order doesnt help.

Connect correct wires to correct cylinders and coils then you win.
