Well, the results are in . . .
Took the car for a test drive. I think there's another problem other than the fuel pump. The car pulls hard above 4k, but i still get some bucking and hesistation up until the secondaries open up. It seems to happen more when throttle is more than 50%. Definitely does it with open throttle, atleast until about 4k, then it runs smooth.
Any ideas what would cause the problems at lower rpm's? The car has 72k. I replaced plugs, wires, coil pack 2 or so yrs ago, might be 2.5yrs. I don't think they are causing the bucking problem. Would a dirty maf cause this? I don't get check engine lights or anything. Because the car does run smooth at higher rpms, I'm thinking it's not a fuel problem.
... Strange indeed!
