Just changed the fuel pump. Prior to having it diagnosed by the dealer, the car ran great, although it cranked a while before starting, then just wouldnt start. Never had a problem with the idle.

Once I replaced the fuel pump, the car started perfectly, and still starts fine but now runs very rough and I am not comfortable driving it. When diagnosing the fuel pump, they said the throttle body needs attention, could this suddenly be a problem causing this type of change or am I still experiencing problems with the fuel pump?

I am fairly handy, is the throttle body something I can work on or is this best handled by the dealer?

Any advice opinons welcome.

Thx
