Idears? Yep. Got some...
- pull any/all DTC's pending or otherwise (may not have a CEL)
- Replace fuel filter
- clean MAF
- clean TB
- have ye injectors professionally cleaned & tested
- did you use new boots?
- did you use dielectric grease?
- what plugs did you use? Gap?
- fer chits & giggles - drop ye spare and remove & inspect ye FPDM
- how old are ye front O2's? If > 80K, think aboot R&R'ing them.
... fer starters.....
After the low-hanging fruit, may need to delve deeper.
BTW - on a site this huge, merely 'looking' is next to useless - you need to leverage the Advanced Search function to really find anything relevant. Suggest you begin bootstrapping yerself - will serve you well in future...

Agreed with double-checking connections. Those COP "springs" are a PITA, and I'm never sure that they are secure.
