2F popping sounds.

[Cruiserhead05]

Driving down the highway today and all of the sudden when i let off the gas the engine is making a popping sound. sounds like its coming from the exhaust manifold?

Sounds like the throttle positioner isn't working (I'm assuming it is a carbureted engine and not the FJ80 or UZJ100). This is pretty common on "desmogged" engines or maybe the VSV isn't working.

If you are talking about a small backfire, I had that until I adjusted my carb. I think the carb adjustment is listed in the FAQ.

I suspect the ABV. RustyNailJustin had similar issue, and that was his problem.
