Hi, I'm very new to this but wanted to see if I can get some feed back on my problem. My Accord is a 2003 with 250,000 miles. It was running good then I started noticing that it was losing power. When I'm at 30-40mph the RPMS go to 3000 and stay there and I can't go any faster. It doesn't shift over. If anyone can take the time to give me a few pointers, I would appreciate it.
