Pinion snubbers.......thankful for this forum

I have 87 GN with Alky kit. When I floor the throttle, the alky kicks in and the car runs great. But, when I let off the gas, the alky keeps pumping so the car will hardly run. I have to shut off the engine and wait a few minutes. When I start it back up, it runs fine until I floor it again and the alky stays on after I let up. I haven't had this problem before. Can anyone tell me what's wrong?

Could be Map 3 sensor
Unplug it and see if you still have the problem

no very bad advice dont unplug and try again the map is needed to turn alky on and alky is needed for high boost
you didnt say what kit you have ... if its an alkycontrol kit call julio at alkycontrol

 

[conn84gn]

Let me clarify
Turn Key on, turn ALKY pump on, turn dial up and see if you hear the pump increase if you hear the pump increase could be the MAP3
Turn off key Disconnect MAP
Turn Key on turn ALKY pump on, turn dial up and see if you hear the pump

True

Keep it up, and you'll end up with a crankcase full of alky.
Turn off the alky, and turn down the boost. Or, your next thread will be asking how to pull the engine.

It is Alky Control.

Was check valve recently added to the MAP sensing hose?

 

[Pronto]

I had a MAP fail and it turned the pump on full blast.

 

[No disintegrations]

It sounds like there is a check valve where there should not be.

 

[pacecarta]

or the line to the map has a kink in it holding pressure

 

[turbojimmie]

I contacted Julio and he had me send my controller in for a check. He should get it Monday or Tuesday (22 or 23 June). I'll let you know what he says.

No.

You're right about that!

I tried, but I'm too deaf to hear the pump.
