Sudden loss of efficiency!!-advice needed
Hi guys. About 3 weeks ago I noticed that my car has been getting about 10-20% less range on a tank than normal. I would average about 480 km or more per tank before my gas light would go on. Lately my gas light goes on around 415-425 km. This past week I did A LOT of highway driving, which I would usually get up to 550 km before my gas light goes on but it went on around 430 km. This started happening right around the same time that I had my car lowered and alignment done but I highly doubt that had anything to do with it... Has anyone experienced this? Any advice is helpful!! TIA

Check tire pressure, clean MAF, how many miles on spark plugs? Alignment give any issues? I ask because the contact patch may have changed slightly (that's a wild arrow tho)
Eta: maybe clean vanos sols too? |
