I need some help !

Hi all..
just picked up a 1990 convertible automatic
Decent enough deal. Until this thing started running like crap..
Starts up fine cold, then starts missing and slowly starts running worse the warmer it gets..I have done rhe following
Plugs , cap ,rotor, wires, map sensor, tps ,cts,
fuel filter, and cleaned Throttle body .checked for vacuum leaks but was usable to find any.
I checked the fuel pressure it was about 43 with out the car on and about 30 with it running.. .. any help will be greatly appreciated

Just a guess...If your injectors look like either one of these, they're probably the originals and need to be replaced.

Otherwise the best thing to do is get an OBD-1 scanner so you can see what the computer is seeing.

cts has been changed. I didn't change the ignition module as my experience with them has been dead or alive. I could be wrong about that
