About 2 months ago my sister was driving on 95 North & the driving belt came loose on her 2004 Toyota Camry. She kept driving cause non of the cars were letting her get through the shoulder. It took 8 minutes & 5 miles to get into the shoulder lane. Anyway, My mechanic said that she blew a head gasket. We got the block cylinder fixed with a new head gasket but now it still runs with no force. For example, I would punch the gas and it will pick up slow & once it speeds up the RPM goes high & steady. I be driving on the highway 70 mph & the RPM stays on 4 rpm holding steady. When I let go the gas the RPM goes down slowly along with the speed. My mechanic doesn't know what it is but I'm guessing that he didn't adjust something to shift the speed. Does anybody know what it might be? PLEASE DO NOT ANSWER FOR POINTS!!!
