    Replaced the throttle position sensor, fuel pump and o2 sensors. Car will start but won’t run unless foot is hard on the gas. Giving codes for tps( tried that) and a code 35( which is strange cause that’s for the turbo model) just can’t seem to diagnose the problem! Replaced fuel pump and it started up and ran for a couple of minutes but started the same problem again! Help!

    Having to keep your foot in it to keep the car running is never a good sign. You seem to have replaced the usual parts that go bad. It could have a problem with not getting enough air in the mixture and opening the throttle bore keeps it running. If you keep setting TPS codes, even with a new part, there is still something wrong, whether it be wiring or a bad computer. I would keep looking in that direction for the main problem.
