90 Mitsu Miriage
 

{offtopic} Hey guys I just picked up a `1990 mirage for a little daily off CL.

Drove it home from elsinore to san bernardino and it ran fine, right when i got back to around riverside though it started acting up on me.

When I give the car gas it seems to sputter and its like the car isisnt able to go and jerks back and forth then it will pick up, this consistently got worse as i got closer to home. the car doesn't do it when its cold and being started for the first time in the day. but it occasionally has like a rough idle like its sputtering sometimes.

I was trying to read up and find out the cause and im looking at a few different possible reasons.

Spark plugs/Wires.
TPS senseor.
Catalytic converter.

Does anyone have insight on this and can shed some of their car guru info with me?
Would be appreciated.
