Hello new to the forum and yes I'm a girl. Need some help figuring out what is going on with my truck. I have a 02 4.7l ram 1500 sport. When I bought the truck it would crank and throw codes for a misfire on several different cylinders. I put all new injectors, plugs and coil packs. Started throwing only one code for cylinder 2 p0352. Changed the coil pack now I have no codes. But it still smokes black soot out of exhaust and dies when idling when you are driving it has no power can only do about 25mph if your lucky barely goes up a hill. Could it be a stopped up exhaust system. Oh yeah I took the upstream O2:sensor loose and the readings on my scanner didn't change at all

Did you physically remove the 02 sensor from the exhaust? Could be a clogged cat.... could be a bad temp sensor as well. Will your scanner read live data??
Does it run ok at cold start, then start runnin' crappy after a couple minutes???
It's running rich. (black smoke) Need to figger out why.![Big Grin](https://dodgeforum.com/forum/images/smilies/biggrin.gif)

Thank you for getting back to me so quick yes it runs bad after a couple of minutes no I didn't take the O2 sensor off the upstairs one I just unplugged it it's not throwing any codes now like I said before I had misfires and then I had open circuit cylinder 2 and I've managed to get all the codes gone and drove it for a little bit can't get over 25 miles per hour the warmer it gets the worst it runs but what is happening when I'm driving it it gets worse but it also when it starts pulling the black suit out of the tailpipe it'll kind of get faster or go faster get a little bit more speed but then it builds up again or whatever is happening and it will slow back down I have a good scanner yes it does relive data what would you like to know about it
I can always take screenshots of the live data and send if I need to
