I switched my opti, cap, rotor, plugs and wires today on my 95 Formula (I also removed the A.I.R pump and capped the vacuum lines). The car cranks for a while before finally starting, idle appears smooth but it bogs and backfires out the intake manifold.

I had set the rotor to the same point on the cap and made sure the opti was sitting flat (and yes it slid right on under it's own will); however I think I rolled the car backward to move the dogbones? on the crank to be able to remove the old opti. I'd imagine it was very possible to mess up the timing by doing that although I can't find anything online about it... I only hooked up the radiator, MAF, and vacuum lines.

Is it possible I messed up the timing or did I do something else wrong? Or am I possibly missing a sensor or something?
