Default Help car misfiring

The car was down for a few days. I was putting a fuel pump in it and finishing wiring up the nitrous. When I went to drive the car it was misfiring real bad. I checked the codes it showed primary secondary coil malfunction P0358 P0351. I switched out the coil packs and it is still throwing the code. I am at a loss. Can someone help me out--I need the car!

btw this is a 99 ta

I've changed the coil pack 3 times now. I changed plugs and wires. I've checked the grounds on the back of the heads. I've checked all the pins in the ECU--everything looks fine but still throwing codes. I am at a loss now. Please if anyone else has any information please let me know.
