new o2 sensors and still stalling

hey guys,

to start, thanks for the help with my previous thread.

for the last 10 days or so my car stalls whenever the rpm's go below 800, ie. whenever it idles after warming up. i pulled the codes and got a code 24 (right bank o2 inversion error). after running the dianostic procedure, i found out that it was a faulty o2 sensor. i've now replaced both o2 sensors and my car is STILL stalling in the same f**king way. there are no more codes that are being displayed. does anyone have any ideas? fuel pump or injectors? ICS? i'm running out of ideas.

it drives beautifully, i just have to make sure that the rpm's don't drop below 1000.

thanks guys,

I don't believe the O2 sensors are even used at idle, so bad O2 sensors shouldn't effect idle.

Vacum leak maybe?

Try adjusting the TPS - page F2-150.

if the TPS is that lil screw that controls your idle, then i would go with IanL. warm up your car then adjust it so your idel stays around 800

doubt its your TPS...

the tps is on the side of the throttlebody, u undo two screws & turn it til the proper voltage is being output.

Might be a vac leak. Did you reset the ECU after replacing the o2's?

I just had the exact same problem, when warm it would struggle to idle and usually stall. Air leak in the big hose that goes from air box to inlet manifold (was split). Examine the hose carefully for splits.

that's funny because i found a a crack in the air intake tubing when i was leaving work today and taped it up in an attempt to solve the problem and ... voila! she now works wonderfully again. i just got home and saw your messages.

and i figured that the o2 sensors wouldn't affect it, but the code appeared at the same time. i guess it was just a wierd coincidence. thanks again guys.

coolant temp sensor? It starts to adjust the fuel when the car is warm but won't affect the way it drives until the car is fully warm.

but once warm, if the CTS is fux0red it can cause the car to run like crap, stall, and sound like a dirt bike. They are 18 bux new from autozone and easy to replace.
