I have a 2004 Dodge Ram 3.7l v6, 5 speed. Just last week on my way to work my truck started misfiring and I barely made it to my office. So I started with the basics, and changed all the plugs and all the ignition coils. Nothing! I then read that it could be a bad MAP sensor, so I go get a new one and put it on. Still no fix. I then figured my best bet would be try to make it to Autozone and get my code read. On the way it dies multiple times and barely has any power whatsoever. I make it there finally and the code says bad ignition coil #2. Well knowing I got all brand new ones I figured maybe i didn't connect it good or something, so I disconnect it reconnect it push down on it and take off home. At first I'm thinking I fixed the problem cause truck sounds normal, is idling fine, and have some power back. Until I reach 2200 rpms it stalls. No matter which gear I was in, the truck was fine until 2200rpms. Even in neutral when revved up it would stall. So now I'm stuck again. I continue reading and find that possibly the TPS could be bad, so I replace it and now my truck won't even start. Even after re-installing the old one it will not start. Will turn over very strong but nothing more. I really need help with this. Thanks
