There are a couple items I would recommend that you check. First, check the fuel pressure to see if it is at the proper level especially while you are revving the engine. If not replace the FPR. Next, check the ignition module it may be causing your problems in not transmitting the proper signal to the coils when necessary. Lastly, you may have bad fuel injectors. I had a V6 that acted like it had a potato in the tailpipe. If it put it in a lower gear it would run fine. This may be your problem. Hope these suggestions help.
