Why won't my 2005 Dodge Grand Caravan accelerate?
My 2005 Dodge Grand caravan is having real issues accelerating. I have had the wire and plugs changed, air filter changed, tires changed. I have given it a few injector fluid treatments, and it seems like the issue is getting worse. When I'm on the highway, it won't go above 40/45 for awhile. It will eventually speed up, but then it will lose acceleration and slow down again for several minutes before it regains speed again. I have almost 138000 miles on it.
