Lol, you’re right there’s no cap and rotor, I’m getting my vehicles confused. The new coil made no difference so I’ll probably throw t he original back on to avoid any complications that may have caused. I think I went with NGK copper plugs and wires, but I’ll double check. I got it from a friend and he said this misfires just started randomly. All he tried was replacing the motor mounts and that didn’t help. The car had been bd tiring and there was lots of evidence of rodents u see the hood which is partly why I’m suspecting an electrical issue. The knock sensor wiring had be an chewed on. All of my spark plugs looked fine when I checked the compression, but I’ll take a look again now that it has some miles on but he new plugs. I appreciate the help. I’ll report back with my findings

TPS and knock sensor have both been replaced recently. The old knock sensor was cracked like you mentioned. it is an automatic and I’ve heard of this. I’m not sure if the axles have been replaced at any point so I might try getting some oem ones. It smoothed out a little in P and N but the vibration is still there. thanks for your suggestions. I’ll try the propane into intake and checking out the battery cable. I have have a charger that shows me the voltage constantly when I’m driving. It’s usually 14.1-14.5 when running and drops down to around 12.8-13 while I’m rolling down all the windows. I sometimes notice more vibrations when I use electrical components. Does that sound normal for voltage?

Hi All, I’m new to This forum although I’ve been lurking around with no account for a while, but I need some help. I have been trying to figure out an intermittent misfire on my 1999 legacy Outback for over a year now and I am not having much luck. The car runs and I daily drive it, but it vibrates at idle, especially when in drive/reverse and I have intermittent misfiring when driving, especially at around half throttle and when going uphill. If I push the gas pedal down the misfire always goes away. It also misfired worse when using anything electrical (windows, ac, turn signals, headlights). I have a CEL for engine misfire cyl 4. I have recently replaced battery, alternator, spark plugs, wires, and coil and it seems like I have a strong spark. I did a compression test and I have 165 psi on all cylinders with very little variation. I swapped fuel injectors 3 and 4. Misfire stayed on cyl 4. I tried cleaning and then replacing with a reman injector #4. No change. I’m thinking there could be a problem with my injector wiring, but I don’t know to test for this. Can anyone point me in t he right direction? I’m going to try cleaning my grounds this weekend. Can someone tell me where the most likely culprit would be? Any other ideas on what to check?
