What plug type did you install? Is the CEL on? Double check your firing order as you may have 2 (or more) wires crossed. Fuel shouldn't be that bad. Was it sitting outside the whole year it was down? If so pull the airbox open and check to be sure that no critters built a nest in there, thus restricting the air flow.

Did you get it tuned for the top swap?

This.

It may sound like its running great, but is it really running good?

No it's not good to go your probably getting tons of KR and will likely blow this motor if you don't get a tune or headers or some flow mods.

[98regal]

have cat delete and high flow muffler i no i need a tune but if u guys say its bad to drive it as is then i gotta finda way to zzp can they program it if i just take out the pcm and take it there

take sc belt off drive to be tuned, no worry's.

you really want headers before you tune it. it needs to breathe more, well exhale.
