got a 98, blew the motor and got an 03.. swap everything over that i needed to run..also installed headers, turn key and engine starts revs to 2500 and then dies...if you hold the pedal down to about 1100 rpms, missing like a mofo... now i was thinking maybe there was a vac leak, but i ruled it out... checked spark=good injectors=good the only thing i can think of is crank sensor or cam sensor....unless there is something im missing here or cant think of...someone please chim in and help out!
