three things..
1. i made a thread a while ago mentioning a pending p1133 code (upstream o2 sensor insufficient switching or something) that pops up every once in a while. since then, i've noticed that it only happens on the highway when the car's been running for 10-15 minutes. i looked at the o2 sensor reading and its perfectly normal at idle, driving on side streets, and the first 5-10 minutes of highway driving. however, eventually the readings are only switching between 500 and 800 mVs. anyone know what could be going on here? (and no i'm not looking at the post-cat o2 sensor :P)
2. my ultragauge is showing the engine going into open loop for a couple seconds as im getting off the highway. is this normal??? (and could it be related to the o2 sensor problem? o.O)
3. has anyone with the 4t45-e had their transmission rebuilt at a shop? if so how much did it cost? i just want to know what i should be expecting if my tranny ever shits out on me xD
