Kinda a weird questions

There are a few things that I have had all year

code 23 tps voltage it is there every time I start the car ? I have talked to another guy with an LT1 and Gen 7 and has had the same thing?

Is there anything that might pop into your head on what to look into?

2nd...

the car all year has had a miss???? but the miss is intermittent...

you drive the car and it feels like for that one sec something is Turing off it is a real dead spot, it will do it under light load under 3000rpm or if you are trying to pass someone on the highway under 1/2 throthal, I don't think it is doing it at WOT...it didn't show anything on the dyno......



what should the WB02 line look like when driving around town......mine is spikeing up then down..not very smooth at all....should it be straight and what should I set the read time at..

thanks
