No, it's not the TPS or the injectors. It could be a bad fuel pump, a bad coolant temp sensor, a half dozen other things.
Take it to a qualified mechanic and PAY to have it properly diagnosed.
Otherwise you're gonna throw another $500 in parts at it and STILL not get it fixed.
Tell them you are willing to pay for 1.5 hours diagnostic time.
I'm an ASE certified tech, btw.
