Hello,

I have a 92 lesabre and this is the symptoms:

Once warm and idling if I try to give it any gas, the car stumbles and sometimes it stalls and dies. i have checked fuel pressure, at idle it has 37 pounds pressure, and fluctuates accordingly when throttle is applied. I just replaced the mass air flow sensor today, and that was not the issue either. The car is giving a code, but when I looked for the 12 pin dlc, I couldn't find it. I was looking under the driver's side dash, and there are no female connectors visible. I am curious to see if it is throwing code 41, as I have gathered the problem may be the crank sensor. Where exactly is the dlc on the 92 lesabre? Any input to this problem would be much appreciated. Thanks for your time, and have a great day.

 

call your local dealer & ask 4 a service tech. They will be able to tell you where to look over the phone.

 

I am hoping someone has some insight for me here. I have a 92 Buick Lesabre that I cannot figure out. When it gets to running temperature it starts stumbling and falling on its face, even stalling. It is only throwing code 41! Also, the Service Engine Soon Light goes off and on, like there is a short somewhere. This is what I have done thus far:

1) Changed the MAF (Mass Air Flow)
2) Changed the Harmonic Balancer and Crank Position Sensor
3) Changed the Cam Sensor
4) Changed the ICM (Ignition Control Module)
5) Changed the 3 coil packs
6) Changed spark plugs and wires

All these parts were replaced with new parts, and I bought the GM alignment tool to put on the Crank Position Sensor (b/c I messed the first one up trying to eye-ball it) I don't know what else to do, other than change computer. But I feel like that's not it either. It only does this stumbling and stalling once it is warmed up. Has anyone else experienced this?

 

I have also checked the fuel pressure and it is within specs.
