Car idles rough, has a miss to it..., Fixed! Close. Options

[joeladam02]

Just put to a new 5sfe engine in my 98 GT...Running absolutely terrible!
Tried O2 sensor, Tried plugs, Tried Wires, Tried Cap and Rotor, Tried Resetting the Timing.

I've been told that the timing is controlled by the computer. Is this true?

Also, someone told me that since the old engine hadn't run for a while and the battery was unhooked for so long "it might just need to run for a while so the computer can reset/recalibrate itself". This sounds like bs to me, but hey, at this point I'm willing to try almost anything. But at the same time, won't it damage my engine by running with a miss if the timing is off?

All input greatly appreciated!
Learn me!

You would need to swap the distributer, egr, and one other little thing (I just can't remember what it was) from the 98 to the new motor. Presure2 and lagos should remember, me and lagos helped presure2 put a 98 motor into his 94 and I remember we swapped those things.

did you change the timing belt ? rayme could be right, could of skipped a tooth.
