So I bought an 09 Journey drove it home with just what I thought was a misfire. Fixed the misfire or so I thought, still reads cylinder 5 misfire even though I replaced the fuel injector, the spark plug, and the coil. Oh and while I was replacing those things I noticed on Cylinder one that someone had put their own plug on there (I could tell by the wire job and the fact that the plug was burnt) so I put a new plug on it. I went to the junk yard and got a new to me/ used tipm, throttle body, and ecu (I thought it was just plug and play) well the ecu didnt work it just put it into the security mode. When I try and start it sometimes it acts like a dead battery, another time the throttle starts going nuts and I have to take the relay out of the fuse nox then disconnect the battery because it is still going nuts, When I jump the started relay the starter is just fine but those times that I try and start it and it like comes and goes and acts like its dying. Im trying to think of everything that I have done I have spent so much time on this vehicle its not even funny. I saw that there is a lawsuit and all this on the tipms but my car has no open recalls. I put the tipm in from the junk yard and I got it to start once after that I can jump it and sometimes it will work but my jumper cables have to be on just so otherwise it wont do anything, it will even have zero power no lights no nothing but i jiggle the jumper cables and it will come back to life. I dont know what to do anymore am I just going to have to take a huge loss and take it to the junk yard(trust me im so irritated with this car it might make my day) please any help would be awesome!! I forgot to mention I also bought a brand new battery, oh and I took a multimeter and when I put it on the tipm sometimes there is no power going to it and other times it has normal power..Im at a total loss as to what to do next so again any help would be awesome I am even taking apart and looking at all the wires just to see if i can see anything oh and yes i have new battery cables also. ok thank you!!!
