EML question
 

To keep it short:
EML light came on and the rpm jumps whiles cruising, idles horrible and big power loss.

Ran codes:
P0221 TPS B
Range performance
Tps A circuit P0121

Obviously its one of the TPS (simply fix) but which do I buy? The Front TPS or the gas pedal assemble (I have smg)?

This happened a day before I went to Iowa for work till November!!!

Thanks in advance

You can test both with a voltage meter. Search. I'm having the same problem but my EML light only comes every few months. I'm going to test them this weekend. I believe there are some videos on YouTube.
