Codes thrown- a few quick questions?

[CEMeyer]

My truck started acting funny, check engine light, od light flashing, went to limp mode. I went home pulled the codes, p0123, p0221 & p0470. The first two are tps code which I am sure why it was acting funny. Do I need to change the pedal assenbly or is there something else I can do? As far as the exhaust backpressure code, new sensor, clean tube or because I gutted/unplugged the ebpv?

Yes, you'll need to change the pedal assembly, you could swap it with a known good one to see if it helps before purchase.

As far as the 470 code, it could be anything you've already mentioned.

No need to get testy.

The 94-97 forum is a little bit farther down the main page, post there they may be more help...R
