1. You need to be a bit more patient... TTT it every 15-30 minutes isn't going to get you an answer any faster (It will probably annoy people and they won't reply at all...)
2.
Per the stickies in this forum...
P0121: Throttle Position Sensor A Circuit Range/Performance
P0134: HO2S Circuit Insufficient Activity Bank 1 Sensor 1
3. Check all the fuses... The PCM is finding your front driver side O2 sensor is dead or switching too slowly... Regarding the TPS code ... SEARCH this forum for P0121 and you'll find your answer ... most likely the thread entitled: "New sensor still throwing 121?? "
Regarding the idle sucking ... fix the P0134 error first... try swapping O2s and see if the code follows (after you've checked your fuses) ... if it's a bad O2 get a new one, then start tuning (Search this forum... idle tuning threads are ALL OVER and alot is covered in the stickies... you just need to use the SEARCH feature of this board...
