How long since a tune-up? Any applicable mil codes? You can check those codes yourself. You turn key to on just till dash lites come on, no crank. Use a jumper wire between the A & B terminals at the datalink connector. The mil lite starts flashing, you count the flashes to get the get the codes. Your looking for two digit codes.
Use a gage and check fuel pressure? Maybe the system is going too lean when you open the throttle?
