240 Volvo 245 Extremely high Fuel Consumption
Hello everyone - This is my first message in the forum so quick intro: Proud owner of a 95K miles excellent condition Volvo 245 with auto transmission. I live in Argentina.
The problem: My Volvo 245 consumes 25L/100 KM ... yes, you are reading right and I can do maths :)
I have no Check Engine light on, and I know it works because some months ago it lighted on and after replacing sparks it went off.
I have an exhaust manifold leak and that long flex pipe with a hole. Additionally, I remember using starting fluid back in December when I bought the car (from a friend) after 5 years seating (wanted to check if the engine was locked). I shot it from the air filter box so it went through the MAF Sensor :(
What it really confuses me is the no Check Engine light on. Every time I measured the consumption I did after refueling it and 100% of the trips were city trips and high acceleration pretty often.
When the car starts it idles high but goes back to normal after it is warmed up and the car moves from Park to Drive. However, sometimes when I go back to Park, it idles high again.
I believe first step is to clean MAF sensor just in case. Any tips will be much appreciated.
Thanks in advance!
