ok so my exhaust was vibrating cause my CAT heat shield was punctured...so i went to a muffler shop to have it changed...he told me its fine and that i should jsut cut off the heat shiled which was making the weird noise during acceleration. I also noticed the CAT/Exhaust had a weird smell to it...cant describe it. I know its coming from exhaust though. So the muffler guy told me that the engines getting to much fuel....and its not burning it all. Could this be due to my TMS chip..since it adds more fuel and air aprently to my mixture?

I would think they thought about this kind of problem....


so what do u guys think..whats the smell from.
If its gettting to much fuel how can i fix it?
Should i take it to a mechanic..my dad said he might be able to adjust it...


???

Does the smell, smell like rotten eggs kind of? That smell is one sign of a cat going bad.

you can't cut off the cat...won't pass smog without it.

But you chip could be adding more fuel to your engine to reach a better fuel to air ratio for more power. But not sure how your chip works exactly

I'd do some new plugs, cap and rotor. Also unless you really know what you are doing don't mess with the AFM, that is the last thing that you should tweak to try and fix an air/fuel ratio problem.

The AFM is the air to fuel mixture. But on a computer controlled car with fuel injection you are usually not able to adjust AFM unless you have a stand alone fuel system with a completely adjustable fuel map.

In other words, just get new plugs and see if that helps.

BTW when you take your old plugs out see how they look. They should not be greasy or sooty at the electrode, but rather a dull metal color. If they look like they are still good and have plenty of electrode left, approximately .040-.060" (40-60 thousandths of an inch), then you might be able to just regap them and solve the problem. Check your owners manual for gap length

AFM is the air flow meter. Its the thing attached to the air box in the E30. Later cars have an AFS, air flow sensor, which is just a wire that reads how much air is going into the engine.
