1983 380 Sec Help!

[Tims450SL]

Hey guys- got me another one- a nice 380 SEC so I need a few helpful hints-

1. My car runs weird and just curious- is there catalytic converters? could be a bad one if they have it-

2. I have a smooth running engine at park, revs great smooth and really powerful. But in gear driving it seems like it is bogging and misses alot- also when I start it - it kinds hesitates to start like when a distributor is way too advanced or just out of whack.

3. I have no history about fuel filter- which is something i will replace, but there is like a weird feeling - a major miss- but the wires and cap appear to be new- I just wonder did someone mess up the car? Could the plugs be wrong?

I appreciate the help I really do- Any and all advice is thanked in advance!
