OK, so I got the car back after the replacement of a crank angle sensor, coil, and fuel pump relay.

Every once in a while, especially when the motor is under stress (going up an incline), I feel a minor flutter as if the car is missing, but I don't hear anything. It's not the kind of bucking that happens when you have a bad air mass meter, or a sudden cut-out for a bad fuel pump, clogged fuel filter, or if the distributor is bad.

It's just momentary, and I don't hear the engine change tone.

I took a look at the transmission fluid. It's at a good level and it isn't black or foul-smelling. I also looked at the way the spark plug wires are routed. I made sure the plastic holders kept the wires off the engine.

Is there anything else I should be looking for?
