Testing Opti/Electrical

[LS1ow]

hey guys were finaly about to drop the motor in to my Z but we still got some work to do. 2 days befor the accident we did the intake manifold swap on the car, in those 2 days we ran into some problems with the car. during normal driving all electrical power on the car would cut of and sometimes it would even stall. the problem seemed to happen around 2k-3.5k. i was wondering if it possibly had to do something with the opti? or perhaps something else? thanksss

Opttiiiiiiii.

How long did you let the intake sit before you started it up?

[LS1ow]

what you mean? we gave the sealant time to settle if thats what you meann

[LTb1ow]

Well I usually wait a good 24hrs before driving it after torquing down the intake.

finished it at like 9pm and i didnt start it up till the drive to school in the morning.

Did you check for any codes? An opti issue should result in a code being set. I'd start with looking at groung wires, check coil wire, Opti, and ign module wires connections to ensure they are tight and there is no corrosion etc. Make sure you didn't pinch any injector wires.

definitely sounds like a ground/connection issue
