I have a 1994 Oldsmobile Cutlass Cruiser 3.1 with an intermittent engine power loss during acceleration. Usually it occurs just after leaving a stop sign or light once or sometimes twice in a row. It is not a hesitation - it is a very abrupt loss of power. I've kept up on the standard maintenance very well and the car has 80,000 miles, so I would not suspect spark plugs, wires, or fuel filter. It does not have a tachometer, but I am 99% sure the transmission is not slipping or jumping out of gear, but that the engine is actually loosing spark or fuel. This problem is very intermittent, but it has triggered the check engine light a couple of times. The check engine light does not stay on, and when I took it to my mechanic he said to keep driving it until the light stayed on or the problem was more easy to replicate. Right now, if a mechanic went for a test drive, there is a good chance it would not show any symptoms. My mechanic did mention that it may turn out to be an ignition module. I can get an ignition module for about $100 at my local parts store. Is it worth just putting this in and hopping it fixes the problem? Or should we just take the mechanic's advice and risk getting stranded with our 1 and 3 year old in the car with us?
