Black smoke


Recommended Posts

It could be in the wiring harness also. Going thru similar issues now and did put in a new MAP sensor in. That did clear up a lot of my smoke down to a haze but still having a issue with the ECM not seeing the MAP occasionally. Pretty sure the rest my issue is in the harness. You could pull the connectors and clean them up, connect and disconnect them a few times. Then put some dielectric grease on them.
