Check your fuel pressure. It shold be 9-11psi. Run a scan on your engine and see if there are any codes. You might have something else screwing up causing your problem instead of randomly changing parts. Also with a tbi unit, check for avacuumleak under the unit and a soft hose going to the map sensor onthe firewall. If it's soft replace it as it may be effecting your map sensor.
