Thanks for the welcome TXBill! Our check up did include replacing all injectors (we knew that the #1 was about gone so we decided to do them all at once and we did replace the fuel filter. We are going to try and install a different filter hoping something may be wrong with the one we originally purchased. Do you happen to agree with my rationale' about it not being the fuel pump itself since the car performs wonderfully at all other times? Again, I'm not the mechanic but it seems if it were a pump problem I would notice it at all times that I try to accelerate, not just from dead stops.
