druck pressure

[mrizvi66]

When i'm at idle the druck pressure needle keeps jumping from 2 to 5 constantly. What could be causing the needle to keep jumping?

bad connection at the sender

Yep, like Tim said, bad connection or bad sender.

Check for a loose or dirty Faston connector at the sender. The connector should be snug on the tab terminal, and not the least bit loose. After cleaning with Brakleen or isopropyl alcohol, if the connector is loose ... you can crimp the sides of the female Faston with needle-nose pliers, SLIGHTLY! You don't want to close the gap on both sides ... just reduce the gap and provide more holding tension!

Another possibility is the 14-pin connector on the relay and CDI panel on the left side of the engine compartment. Clean the pins very carefully with isopropyl alcohol and a bristle brush ... the pins are silver-plated brass, and the plating is very thin.

If it isn't the connection, sender or gauge defects could be the problem.

Cool I'll check it out when I get home.

Thanks Guys

Its by the crank pulley on most cars. It looks like a 1.5" X 1.5" cylinder with a wire running to it. There may also be a rubber cap over it.

Almost certain to be too much pressure on the druck. Install the electronic druck bypass control valve to keep the dreck out of the druck, lowering the pressure. Also replace all the rubber druck hoses on the car.

FWIW isn't druck just the german word for pressure?

No Kurt, we prefer to keep asking the same questions to see if you old timers have started becoming senile yet
