Cylinders 1 and 5 burn differently?

[Jeff7477]

I just changed plugs on my 1990 GT, and noticed that the plugs out of cylinders 1 and 5 (front 2) looked different than the others. They look more charred and had oil residue on them.

Anyone know why this is? My car burns oil, but it seems wierd that only the front 2 would be the ones doing it.

Maybe because not enough air gets to those 2 cylinders because of the intake design. Maybe someone else will chime in.

Idk but there was another thread about something similar thats only about a day old...it had something to do with burnt plugs or something see if you can find that and check it out if you havent already...maybe it will help? Either way good luck!
