How long since over-all tune-up? Use a gage and check fuel pressure. Any applicable trouble codes. Some of the national brand autostores will check codes for free. If you want to check codes, yourself, you need an obd2 code reader. Your local autostore should have these?

Just a thought, it isn't a tranny issue? If you keep your foot out of it, does it drive ok?
