Ok here is what just happen today. I was coming back from Macomb and the car started running very poor. Throttle respone is terible. At 60 i can give it 1/2 throttle and for a good 3 seconds there is no respone. After 3 seconds, you finally start to gain speed. It did this all the way home for a good half hour. Got home got out my tech 2 and check the codes, i have 2
O2 sensor Bank 1 Sensor 2
O2 sensor Bank 2 Sensor 2
These are both my O2 Sims Why would i be getting a code for if i had Sims in place. Can these go bad and cause the car to run weird? I know my front O2s are good, they only have 10k on them and look good on my Tech 2
Has anyone had this problem before?
Could it be TPS, MAP sensor, ??? I can clueless here.
Help me out guys my car isn't the same anymore.
Thanks Brad

 

As far as I know the rear two 02 sensors do nothing but monitor the cats. If one of your cats go bad the 02 sensor triggers a code for bad cat.

 

if you burned a wire going to your o2 sim it would act the same as if you had unhooked them and i'm not sure about the lt1 but i think if that happens the car goes to maximum retard and pulls 12* of timing out. which would really be a kick in the shins to your power.

 

But if i burnt a wire then why did i get a code for both, instead of just one. But its an idea and I'll check it out. Anyone else have any ideas. I just went out and drove it. I was slightly better but its still there. It feels like it just sucks alot of air for a couple seconds then finally the fuel comes. ????? Its really driving me NUTS!! Help!

 

Going to check the O2 sim wires tomarrow morning.
Anyone else have any ideas until then??

 

Just checked wires on the O2 sims, they are fine. I e-mail TPIS and explained to them whats going on and they think my sims are bad. I am about to order some new O2 sims if i can't come up with any more ideas to check.
As for the car, i drvoe it today and it was alot better, almost back to normal. But it does that. I will come and go.
