My Rpm gauge bounces back and forth while idling on my 1990 B2200. Any suggestions?

 

Are you saying you rev counter is faulty? or are you sayin the actual engine idle speed is fluctuating?

 

Grim - Don't we all just love posts with inadequate information ????

 

Engine idle speed is normal. RPM gauge just bounces back and forth. when I put it in drive,it stalls out.

Apparently, the engine idle speed is normal. RPM gauge just bounces back and forth. When he puts it in drive, it stalls out.

 

So an automatic.

I wonder if his idle speed is too low.

I wonder if he has stock carburetor or Weber.

I wonder if he has installed a new fuel filter in recent history.

I wonder if he has monkeyed with ignition timing.

I wonder if his spark plugs have been changed in recent history.

But I don't wonder too much.....

 

It might be best to just disconnect the rpm gauge. A lot of vehicles dunt have one an you wunt really miss it.

 

I wish I wondered like you do.. I might find the problem
