hi everyone i hope you can help, i had replaced my mas on my 92 240 but there is not an change it kept on stalling and running like crap but when i unplugged it the car runs great what else can be causing this problem i'm guessing it's not the mas thanks

 

You need to reset the fuel system adaptation when you replace the meter. You can pull the fuse or disconnect the battery. Just make sure you have the radio code if you disconnect the battery.

 

... also check to make sure there isn't any condensation with the fuel system fuse by the ignition coil... here's something you might want to look into buying for your car... cheap and will save you a lot of trouble when you can't figure out why the car won't start... http://ipdusa.com/Volvo-200/Electric...9-257-335-162/
