See if there are any codes stored by the computer. You should be able to find places that will do it for free. Check the throttle position sensor & Idle Air Control. It could be a problem with the cold start circuit, supplying too much fuel when starting cold. Rent/borrow a fuel pressure gauge from a parts store and see what sort of pressure is present at the regulator/test port.
