I need help with this misfire guys. Fault code said cylinder 4 misfire , so I replaced the plug and the Coil pack . Can ran fine for a day then started again . The same code appeared and also cylinder 4 injector low voltage I believe. So I replaced the Injector and it's still missing. Anyone have any helpful information to solve this problem ?

Also my AIR SUSPENSION light came on. The car still sits at a normal level but the compressor didn't turn on , so I swapped out compressors and still nothing. Smh any suggestions ? THANKS.
 
did you replace the coil boot? check the old coil and see if it has any white spots on it. normally water will get down there and swell the boot up. blow the hole out with air to clear any water out. then put a little dielectric grease in the boot and reinstall.

you have another issue. that looks like a wiring problem to be. the guys here said there are some common issues with rubbing on these motors. that sounds just like your problem. you wouldn't get all those codes from a miss fire.
 
Lastnight my heavy friend got in my car and the compressor starting buzzing lol . Smh is there a ride height sensor ?

Just checked the car out again. When I replaced the injector I forgot to connect the EGR valve. But the cylinder 4 misfire is still current. I'll check the harness for a broken wire. Thanks

there is a leveling rod on the rear of the car, its normal. he must of been pretty big
 
Fixed it , there was a break in the wire. Air bag light came back on . On the leveling rod is there a sensor to detect ride height ? Also the driver side is sitting lower than the passenger side. I sprayed the bags with soapy water ... no leaks.
