DIYPNP Noisy TPS Ground issue
Hi,
After trying out three different TPS I've concluded that my noisy TPS signal must be a ground issue.
Thus far I've done the following
I've also opened up my DIYPNP to check for any sort of physical damage, none found.
Could the alternator somehow make this happen? The power bolt is tight, the controller connector is connected and the bolt that holds the alternator to the block is tight.
Is there anything here that can be cleaned? I know the alternator grounds through the block.
I'm assuming this is a signal ground issue somewhere, because my CLT signal is also noisy. I'm guessing this is also why my car begins to misfire under load.
The car is virtually undriveable right now.

Thus far I've done the following
- Cleaned (with brake cleaner and wire brush) throttle body ground
- Cleaned ground under throttle body
- Stripped paint at the first battery ground location
- Added a wire from the upper throttle body ground to chassis
