Double check to make sure you didn't accidentally unplug and censors on the harness. Also check your fuses. for you ignition.

1997 Pontiac firing order is 165432

Hi, Very carefully. You'll have to get on top of the engine to remove the back plugs.
Just take your shoes off when you do this so you don't break anything. Also prop the hood up so you can access the plugs better. Good luck.

Disconnect any hoses in front of coil pack
you must rotate the engine after removing the engine mount strut bolts .hold the engine with special tool , there is enough room to get at the plugs and remove them .

under hood, look for relay & fuse center box. it has a black plastic cover. u need to unlock tabs to open it then look under cover for fuse and relay diagram location.

FOLLOW THE AC COMPRESSOR LOW PRESSURE TO THE ACCUMULATOR AND EVAPORATOR LINE GOING INTO BACK LOWER FIREWALL LOOK FOR A LINE WITH A BLUE CAP ON IT.THATS YOUR RECHARGE PORT.

The ign coils should be marked. The front cylinders are 1 3 5 and the rears are 2 4 6..... the coils starting from the front is 1,4 5,2 3,6

sounds like the ignition module is going bad.

check the harmonic balancer
if it is soaked with oil, it will slip and change the timing

also check spark plugs and wires
to check the wires find a dark location(no light)
and run engine ,look for sparks
