Hello, I have a 00 S40 that has skip in the idle. Here is what i have done so far.
1. replaced the plugs, didn't fix it.
2. checked the coils all are plugs are getting spark.
2. checked vacum lines for sludge, none!

S0, I wanted to check and make sure each injector was working. So, Undid the cover above the fuel injector rail. With the car running, I unplugged each fuel injector one at a time. I started with 1 and went to the fourth one. When I unplugged the first through the 3rd one, it ran worst each time. When I unplugged the last one it ran the same. So, I believe that the last injector, the one that when I unplugged it did not change the idle, is bad and my car is basically running on 3 cylinders. Does this sound rite to you all. I appreciate any advice you guys can give me.
Thanks
Dennis
