Okay guys this is embarrassing seeing how I do this for a living but I can not seem to figure it out for the life of me and I really need to resolve this issue !!
My 2005 Evo 8 ssl My check engine light doesn't work. My Ecu will show codes for example I have a test pipe. I plug my scanner in and it shows me a p0420. Normal but I have no light in the cluster. I have removed the cluster and replaced the bulb with a new factory bulb and I still have nothing. What do you suggest would be the next step? Now I have been tuned but this problem has been existent prior to the tune but I had my tuner set my ses light for knock. I really want to get this resolved. Please help!!
Also I have a egr code since I have been tuned and I check the vacuum line and sure enough it popped off so I put it back with a zip tie cleared the codes. Drove 2 drive cycles checked it again and it came back so I rechecked the vac line and its still on there ? that also has me stumped
