I have a 96 tracker throwing a P0510 code and also P0420 code could one be causing the other and possible solutions? Don't really want to buy a new tps since autozone has it priced at $422 so any help would be awesome thanks

P0510 - closed throttle position switch malfunction
p0420 - catalyst system efficiency below threshold.
Unlikely that the two are related.
Have you checked the wiring to your TPS for good connection, shorts, etc? If the wiring is ok, have you recalibrated the TPS to see if it was out of calibration?

Jerome, if you want info, you should start your own post, indicate exactly what your car is, your codes, your symptoms!
