@Bykfixer MIKE! I HAVE SOME GREAT NEWS!!! I was teaching my girlfriend to drive one night, and I literally noticed a hiccuped muffling noise coming from the bottom of the car. Did some research, came across a post in this forum I believe where someone had a similar noise, and found this video: So! I took it to a muffler shop, and lo and behold, exhaust leak! Literally paid 80 bucks to get it fixed, and noticed immediately how quiet the car got when I started it back up. Then took it for about an hour drive, and guess what? NO. CHECK.ENGINE. LIGHT. SO FAR! MY GUY! I JUST SAVED MYSELF FLIPPING 1300 DOLLARS ON A CAT EXHAUST COMBO! CAR IS RUNNING LIKE A DREAM! THANK YOU SO SO MUCH FOR THE ADVICE! I literally meditated on your comment while scrolling through hours of videos and forum posts. Hoping the light doesn't come on, and the cats give me another 50-60k miles. Thank you again! Take care brother. I'll see you on the road!

Thank you so much! I got two codes, and autozone tested my alternator. your gut was spot on. They told me the voltage regulator, verbatim. As for codes, I got: P0420: Catalyst System Efficiency Below Threshold ( bank 1) c1201 engine control system malfunction For now, I’m going to get my !Removed! into the engine bay and change the spark plugs + alternator. Thank you so much for the kind words! Really hoping it’s cheap. I want my girlfriend to be as safe as possible on our 6 hour trip. And of course, I love this damn car lol. It’s my second car, and I’d like to have it longterm- at least until we’re forced to drive iphones with wheels. 😄 To follow up: - I wonder if my alternator is wigging out my vsc, which in turn triggers by the engine system code? - Also, would my alternator be causing the o2 sensor wig out in my cat?

Hey gang, Very new here. Apologies if this is in the wrong area. I just purchased an 08 is250 from an older gentleman for about 5k, with 137k miles on the dash. First went to autozone, and they told me my alternator had an issue, but my battery was at 100%. Went to a mechanic couple days after, told me it was fine. Went back to autozone to double check. Same diagnosis (alternator going bad). What compels me to change it; had an issue two nights ago where I had the car doors open installing seat covers. Kept the ac running (accessory mode) to air out a spray I used while adding the covers. Tried to start, electronics started flickering. Car barely gave me a chug. Closed all doors, left it alone overnight. Next day, started a bit sluggish but turned right on. Tried it again, then regular start. Play it safe and replace it? With VSC + Check engine: Car has never given me issues driving. Lights went on, and still no issue. Could drive with no hiccups, over 60mph. Disconnected + reconnected battery, disappeared for a few days. Stress tested the vsc button, and could literally feel the difference in driving. It works perfectly fine, but light came on again and couldn’t use the vsc anymore. Disconnected battery again, vsc is working again. Maybe alternator is wigging out electronics? Regardless, I’m looking to change spark plugs, serpentine belt, and potentially alternator. Going on a trip to PA with girlfriend, and want this car to be bulletproof. Any recommendations/ feedback would be very much appreciated.
