I have a 89 Chevy Cavalier Z24. It has a 3.1 multiplier V6 in it, but I can tell the motor was replaced in the car. I need help hooking up all the cut wires in the engine compartment.

First, the '89 was the 2.8 engine. They started the 3.1 in 1990. I got great mileage with my '90 5-speed Z24. I did put splitfire sparkplugs in it back when they were the new thing. I started getting about 80 more miles per tank with them. You may want to try something better for spark plugs. I also ran 87 in mine with no issues.
