Switched car with the wife and took the Volvo to work today and drove it to school after and now it's idling smoothly as a baby's butt. CEL is still on though, not sure what codes are on there at the moment. Haven't measured the voltage with the new alternator, but no unhappy power failure messages ...

Ok, here's the latest update: It's idling but every couple seconds it feels like it's missing or skipping/stuttering and then it smoothes out for a couple seconds and then repeats the skipping. The CEL codes are P0026 and P0027 intake and exhaust valve control solenoid circuit range. Could I still ...

So far no battery light on dashboard and "power system service urgent" message is staying off. Lesson learned; do not replace the 140amp alternator with a 160amp one even if the parts guy says it'll be ok.

Still waiting for correct alternator to come in. 140 amp is what was in there originally.

Going to replace both Alternator and battery today. Will report back.

It makes no difference if I keep the hose off of the alternator. Also, found that the alternator that is in there is rated at 160 amps, but the original alternator was rated at 140 amps. If I go off of ohm's law V=IR then using the 160 amp alternator could be sending too high of voltage to the car ...

Also, found out that the alternator is intermittently giving off 14.2-14.4 voltage and then sometimes it just drops out to 11.4 (just running off the battery) and then the battery light comes on the dash and the message "power system service urgent" I think this might be due in part to the Diode ...

Well almost out of the woods on this. The intake CVVT Solenoid is making a buzzing noise and the check engine light is saying that both intake and exhaust solenoids are throwing errors. Here's a video of what it sounds like

Thanks mrbrian200.After charging the battery up for 3 days at 750mA and taking it to AutoZone and having them charge it for a few hours on their "fast charger" (not sure how many amps and it's still not completely 100% charged) they put a load on the battery and deemed it good and said there was no ...

Well, I'm going to take my battery in to the autoparts store (Autozone) and have them charge it. I attempted to see if the alternator was connected and it did have one thick wire about maybe 10 AWG coming from the back of it. I'm assuming that this is the positive lead and that the negative is just ...
