I have a 2001 Silhouette Oldsmobile that is stalling out and having troubles idling, it seems like. When I am driving around town, around 35 or 45 mph, the van will start to shake and sputter. Sometimes the exhaust will "pop". When this happens, the rpm's will jump up to 5000rpm and then drop fast down to 1000 or turn off completely. I have taken it to a mechanic and they have changed the fuel pump and the catalytic converter, then he says well maybe the gas gage it messing up. I need help! Still having the same problems, nothing has changed. Do not want to take it back to this MECHANIC!
