When i installed the new O2s last night it fixed the idle issue which I didn’t know was an issue until I installed the new O2s i thought it was just a cam thing.

 

i have pretty bad surge with mine too but i also think i have an o2 problem cause one of mine doesnt really bounce from 0-9?? like the other it stays around 200-600 so maybe thats my problem too...anyone know who has decent prices on delco o2's imma just get 2 new ones i have one bosch and one delco

 

I bought denso O2s i did a search on here and most people like them. Here is their site. http://www.densoaftermarket.com/cata....php?part=o2sn
I bought mine for 80.00 at union auto.

 

After driving it more since the new O2s it fills a lot better but i notice that in any gear at any rpm the stutter is when you very lightly apply throttle.

 

This seems to be a throttle position issue to me now. It doesn’t seem to be anything with a certain rpm. This happens when the throttle is at a certain throttle position which is very light acceleration in any rpm or speed. Does anyone have any suggestion? Thanks

 

Did you ever contact Ion about this issue? Maybe he can help you out.

 

Yea i sent him a data log file and he said that everything looked fine.
