hello, first time user on this site. I have an 1985 Mercedes 190e that I bought last year(about 9 months ago), and the ignition switch had gone out on me so I just recently got it running again. Now the issue fuel. It seems to be using a lot of gas, a lot more than it was before. It's taking an unbelievable amount every day. I was wondering if anyone can give any tips to what could be the cause. I am guessing it needs a good tune up but I am not a mechanic. any advice or info would be appreciated.
