- 05 ford explorer v6
So to start off Im new to working on Ford vehicles. Recently purchased this explorer, it ran well, but its got some miles on it so I decided to give it a once over and do some preventative maintenance. Air filter, oil change, the muffler had a hole in it so i put a new one on, and fixed the broken ground wire in the door and all went well. But after changing the plugs, which are motorcraft, I noticed it ran pretty rough at low idle rpm and would have a slight misfire, also felt like it had a slight power loss while driving but not as rough as when idling. Naturally I thought it was a issue with the plugs so I did some research on the forums read stuff about making sure to check the gap which I didnt at first so I pulled them out and gapped them to .052 (owners manual says gap spec is .051-.056). Still no change, I then thought maybe I had a bad plug wire so I replaced those and still no change. Then I thought maybe I had a faulty plug so I bought a new one and changed out the plug on the cylinder my code reader said had misfired and still no change. After that I though maybe I had a some weird fluke type of coil failure so I replaced the coil and again nothing changed. I feel Ive ruled out the ignition system, I quadruple checked my plug wire sequence. Now Im down to checking for a vacuum leak but Im not even sure where to start, all I can say is I need help. Im extremely frustrated because ive done this on other vehicles before with no issues, and in "fixing" something that wasnt necessarily broken I made it worse and Im having a hell of a time pinning down the issue here. At this point Im looking for any advice on what direction to proceed in before I swallow my pride and take it to a shop.
