Hello, I recently my 93Z and it has a missing problem. I have taken care of the coded issues and a little extra. Two new O2 sensors, a fuel pump and a throttle position sensor. The fuel pump was putting 14lbs. of pressure, replaced it now it runs better. It still a miss though, only under a load though. When I drive down the road it runs good, but when I add some throttle it starts to miss. Any suggestions?
