My problem is that the pass side header will actually glow from just a short trip. The only thing I see a problem being is the fact that i saw 3 wires arc on the pass side. INjectors have 20 miles on em everythjing else is pretty good plus the drivers side is fine its only pass side that is glowing. No vacuum leaks or anything like that. I dunno what do you guys think?

 

Glowing manifolds are usually the biproduct of a clogged cat. Misfiring usually causes a rich condition. Running rich can damage a cat. Try disconnecting the cat on that side and see if your glowing problem goes away.

 

Heres how to check to see if you have a clogged exhaust without disconnecting the cat. Hook up a vacuum gauge to the manifold. Measure the reading at idle. Then measure the reading at 2000 RPM's. It should not be any more than 2in/Hg higher than the reading at idle. If it is, the exhaust is restricted.

 

Unfortunately vacuum level decreases with engine speed.

 

According to my hayes manual, if your vacuum gauge fluctuates as the engine speed increases or vibrates excessively at all speeds then you could have a plugged catalytic converter.

 

no cats on this car im gonna change wires tomorrow Ill tell ya how it goes
