2001 Acura CL car randomly stalls

There is no apparent pattern with the car stalling. I can be traveling at any speed and in any type of weather. The timing can be after I have operating for a while or shortly after starting the car up and driving a short distance. I rarely have an issue starting the car in the morning or after sitting.

When the car stalls is slows down. The radio, ac/heat, and all other lights and electronics remain operable. It usually restarts after about 3-5 minutes.

Please advise. My safety is at risk!

The dash lights do stay on when it stalls. Thus, the ignition switch has been eliminated.

Is it possible for the primary oxygen sensor to be at fault? I am now considering the main relay but it does not seem to be temperature sensitive. The car does not seem to be a problem with starting - not even in very hot temperatures.

The problem has persists for about 4-5 months now and it is getting worse - stalling more and more. It occurred after the fuel injectors were cleaned by valvoline.

1 mechanic is absolutely certain it is the 02 sensor; another is absolutely certain it is the fuel pump; and another is certain it is the main relay.

Please advise

Can the 02 sensor be diagnosed without the check engine code coming on?

A scanner/"acura-honda" diagnostic machine has been applied to the car and nothing came back.

Is this becoming a manufacturer's problem such that the car has a problem that is not showing up on the diagnostic? Acura has checked the car and advised me to change the spark plugs. It has 79,000 miles! The car stalled while it was in their possession and they claim they cannot find the problem at all.

I am having the exact same problem on my 01 Acura 3.2 CL.

Over the last 6-8 months it has randomly stalled. Twice on the freeway while accelerating, a few times in slow stop-and-go traffic, and a few times when I park for a few minutes and return, it won't start. It always will restart after waiting about 5 minutes. There is no check engine light and the battery stays on. I have had it looked at with no luck yet. Were you able to find out what was wrong with yours?

The shop diagnosed it as being a problem with the Crank Shaft Sensor by elimination. Does this sound right?

I am facing the same problem with my Acura CL from last two months. I have taken it to diagnose but no luck, they couldnt identify it yet. Any other way to find the problem. Thanks in advance

When this was happening to me about 3 months ago, I ended up taking my car to my old mechanic who I trust very much and he was sure it was the main relay. Sure enough, he put the part in and its been running great since.

Chelsea. What did the problem end up being with the cl
