I have a 95 tl Trans Am with a miss in the throttle. The codes it's giving me are injector circuit and oxygen sensor bank 2 lean. (Code 18 and 64). The injectors are brand new. A noid light on all of them blinks when you crank the car. Any ideas?

How is your fuel pressure? Fuel pump not keeping up pressure could cause a lean condition.

You need 41-47 at prime, and at WOT. You can simulate WOT by removing the vacuum from the fuel pressure regulator, but it isn't a substitute for WOT testing.

Also make sure watch the pressure. Does it hold for a bit, or bleed down quickly?
