    Default Do not purchase this!

    If you don't mind your engine stalling on quick deceleration you will like this system. Otherwise, purchase a different brand. Personally I like steering and brakes when I need to slow down.

    More info on this on going issue. Since many people have said they have no problems and a few experience the issue I have, I can only guess this is a manufacturing or parts problem. IAC not built to specs? Too slow to react? Internal drilled or cast holes not to specs? Just throwing that out there to see what sticks. I would be also interested to know more about the Decel Fuel that shows on the handheld. If you've been down the tech help road of, your IAC counts are off, the throttle blades are not adjusted correctly, and lastly, you have a vacuum leak! You feel my pain, and I yours. When to cut it loose and ditch this faulty piece is the next step. Or I suppose disassemble the unit in one last effort and see if something jumps out that is not quite right inside. Blocked IAC passage, dirty IAC? Then on the shelf it goes till I decide what to do.

    Most times this is a tuning issue. Not enough fuel on deceleration is the most common issue. With not enough fuel, the engine is not making enough power to keep itself running. You need to log the event to see where in the fuel map it's going.

    Mine ran great for about 1500 miles then just died. Did not want to start. 24 hours later it started, but once I turn it off or if it dies it will not start. Let it sit for over 24 hours it started then just died a minute later. Not sure what's wrong with it.

    It's probably running excessively rich and fouling/fuel saturating the spark plugs. When they dry, the engine will start again. If the spark plugs have been fuel saturated, they'll probably need to be replaced.
    May God's grace bless you in the Lord Jesus Christ.
