car surges
when i drive my 95 aurora slow, like a grandma(10-20 mph) with very little throttle it surges.the tachometer jumps up 500 hundred rpms then just falles.it does this every second.i can get it to stop for a little bit by stepping a the gas hard.but then it just startes up again.does any one have any ideas what might be causing this stuff to happen??
any help would be good thanks for your time.

Sounds like fuel or electrical.
Electrical possibilities: Spark Plugs, Spark Plug Wires, Bad Coil Fuel: Fuel Pressure Regulator, Glogged/Dirty Injector, a sensor (you getting any codes...check engine light?) just a few ideas.... - Drew

Re: car surges
I have 2 95 Aurora's one with 149k and one with 20k and have surging problems with both. The high milleage car had a leaky intake gasket, that was the fix for it and the one with only 20k I had to block off the EGR valve the computor was comanding the EGR on a very low load witch caused a surge. I simply removed the valve and made a gasket without any openings. This makes the ECM happy and I no longer have any surge.
