Car won't accelerate!
1.I drove my 2005 ford escape to dealer driving 60mph told them I hear a whistle, they charged me $1,900. and fixed exhaust manifold. 2.when I picked it up I could hear another air leak front driver side now max speed is 50mph and light ABS and 4x4 are on, they replaced front driver tone ring. 3.when I picked it up this time I still hear air front right and my top speed now is 30mph. 3 weeks at dealer and they don't know why my max speed now is 30mph I went on test drive with the mechanic and he said sounds like transmission. I find it hard to believe, I had speed before they did the work on manifold, what could this be and how do I get them to fix it? can I do harm driving it home every time I go to pick it up and hearing the air leak...30 min drive?
