87 Pathfinder 3.0 V6
4x4
5 speed


Getting an injector leak code (Replaced both injectors with new gaskets and O-rings)

And an Idle Switch code.

(I had the injector leak code when I replaced the injectors as well as after)

I have replaced the Air Flow Metering device, injectors, and O2 Sensor


The truck runs but has no power and pops a lot through the exhaust. The power loss is consistent but seems to be much worse on take off.

When you give it gas it almost sounds like the Throttle Body is whistling.

I don't have a timing light nor do I want to buy one unless timing could definitely be causing this.

Any Idea's on what could be the issue or at least somewhere to start looking?


Edit - Forgot to mention this thing has headers and no catalytic converter

I've been deep in reading here on the boards (God I love the search function)

Could the TPS cause it to run rich which in turn could cause the popping and power loss? If so is there a method to test the TPS via a volt ohm meter or something?

I feel like a kid at a candy store right now for the fact that I MIGHT be getting closer to solving this mystery
