6.0 throttle body problem
I have a nick Williams 102 throttle body. The sensor keeps going bad. I've replaced it with both aftermarket and oem ones and it will work a few weeks sometimes 2 months then just continues going into limp mode to the point where I can't drive it, it'll stay in limp mode. Any ideas on what's causing this?

What year is the car ???…first you have to determine what DTC’s (trouble codes) you have stored…also these sensors are electrical circuits so that has to be looked at before you replace any sensor…this may be an electrical issue.

You are in C6 Tech…your profile says it’s a ‘98 so if it’s an ‘03 what engine is in it with a 6.0 ??…can you please change your profile to reflect that because there are wiring differences year to year…when you start using these aftermarket TPS sensors the PCM is looking for certain voltages in determining if you have a TB issue…what DTC’s are you seeing ??…if you have either a scan tool to look at TPS voltages or a DVOM to look at these voltages that way not to much more help I can offer.

Unless it’s a seriously bad *** 6.0, you don’t need a 102mm throttle body. That 102 is difficult to tune for even super sharp tuners.
A GM 90mm LS2 throttle body might cost 5hp, but will be easy to tune and will likely solve all your issues.
