94 volvo 940 still stalling
Hello, After a year or 2 of stalling once in a while, the car now has an issue.
I have a 94 Volvo 940 turbo with stalling issues. I pulled the code, and got a 1-2-1 Faulty signal to/from Air Mass Meter. I changed the Mass Airflow sensor, as was recommended. Since then the car has a hard start, when it warms up, it runs fine, then after about 4 or 5 minutes (in park, or driving) the car stalls out. Most of the time it will start again, but after a couple of minutes it will stall again. I rechecked the codes, now its giving a 1-1-3 Fuel trim (lambda control) too lean or rich. What can I do to correct this? Any help is appreciated. |

Re: 94 volvo 940 still stalling
I decided to attack this problem again, changed out the fuel pump (which was screaming, making noises) but didn't change the filter, wasnt in stock. The new pump installed and making noises same as old. Planning on changing out the filter tonight. Along with the pump screaming, the car is doing the exact same thing: Starts, idles well for a bit, then stalls out after a couple of minutes. It idles fine if I give it a little gas, then let off, the idle becomes rough, then stalls. Am I on the right track, or is there something else I should check?
