Very low Idle at stop. Runs fine above 1100 RPM. Changed O2 sensor already. Check Engine Code 41, but issue started before new O2 Sensor installed. Smells like running very rich on fuel.

Any Ideas greatly appreciated.

What other information can I give to assist?

 

try check the TPS

 

Sounds like what my 91 accord was doing to me last winter. When I would stop, the rpms would drop so far that the lights would dim and my cd player would restart, and the car sounded like it was extremely close to dying.

I thought it was possibly my alternator, but I never did figure it out because it fixed itself after about a week and I haven't had a problem since.

 

I'll try checking the TPS tomorrow. I have already replaced the alternator two weeks ago.

I check back tomorrow after work and let you know if anything new has arisen.

Thanks for your assistance.

 

And Iacv

 

While you're checking the TPS, It might not be a bad time to clean your IACV (Idle Air Control Valve) & FITV (Fast Idle Thermo Valve) as well. That's explained along with some other good cleaning tips here:

Let us know whether any of this helps.

 

One of your jets could be clogged.. That was my issue at stops when my idle would drop to like 200rpm instead of normal 600rpm idle.

 

Okay,

I cleaned the IACV and snugged up the yellow piece on the FITV, no change in idle.

I then proceeded to the TPS and checked for supply voltage. My Hanes manual says it should be about 5V, there is a problem here. My supply voltage is only 3.8mv.

Where should I look to solve the power supply problem? Is there a fuse for this? or do I need to look for a broken or loose wire? Thanks again for your help.
