Help Please, stalling and hesitation.. Thank You
 

My car has been stalling and hesitation , ............ I Just put a new a filter in , and I still get hesatation , the funny thing about it is when I drive the car without the air filter it has hesatation in the begininng , but after driving it a couple of miles the stalling and hesatation go away , when I put the filter back in , its worse , my question is ...............what else could it be ?? can it be fuel ?? what other filters can I change ??

Thank You

Stalling/ Hesitation
 

First start with the Mass Air Sensor that is plugged into the intake sleeve. Make sure it is clean. As well, check you wiring harness on that M104 engine! They casing falls apart and can inhibit the driveability SEVERELY!

Now, my honest opinion? I would check out the Oxygen Sensor! I had the same problem with my 1996 E320, and VOILA! She behaves again!:)

Uummmm
 

Hi , Thanks for the reply , I need to know were those parts are to check , any pics on this site to show were to look , or can you help a girl out and show were these things are in the car ??? Thanks

Send it over to my e-mail if you want too ??? jubie@cox.net

When does the stalling occur and how often? Does it occur when it running or idling? How is the cars throttle response slow or fast?

I'm still having this problem , any other ideas ??? is there a fuel filter of some kind??

Oxygen Sensor
 

Where is the Oxygen Sensor , in my car , any pics that I can look at ??? Thanks

Or ..........................check you wiring harness on that M104 engine! They casing falls apart and can inhibit the driveability SEVERELY! ,Where can I see a pic of my wiring harness ??? help please .thanks

when the car sits for a few days , the stalling is really bad , I'll take it for a drive on the highway and open it up , and the stalling gets better , but the car still has no balls when floored !!

How do I know if teh O2 senser is bad ?? , can it be checked ?? or do I buy one and see if it helps , ........... it cost around $200 , that would suck if it wasn't the O2 senser and I bought one .

You could damage the mass air sensor if you drive with out a air filter.
it's sounds to me that your car running rich on fuel because the car works fine with out air filter. So the O2 sensor is a possibility, the sensor is expensive but if it never been replaced it is a good idea to change the sensor even if the sensor is working.

What shape is the air filter in if it makes that much of a difference? You need to have a shop see if the air mass sensor voltage is within spec.

the air filter is new , so thats not the problem .
