FYI a p72 is a GSR(b18c) ECU.

Ideally, the car should have a virgin p30 or chipped p28 ECU with the proper B16 Mapping.

If your ECU is already socketed you can always burn a new chip.

For now, check the CEL codes by bridging the green connector under the dash on the passenger side. If you don't know how to do this.. search or take it to a shop where the car can be properly diagnosed.
