I hope you can help me out here, I recently purchased a 1991 BMW 525i with 107,000 miles. I noticed going up steep hills
that the car surges. You can't see it on the tach but you can see it on the MPG gauge as it swings upwards every couple of
seconds and you can feel it in the ride. It has started to get worse and it now surges on smaller hills.
I replaced the plugs and the fuel filter and put in a can of injestor cleaner. I sould suspect the ignition coil but the car has 6 of
them. Would appreciate any tips.
