well when u had the cats it blocked a lot of shit coming out the pipes- I have seen some smoke a little on start up and that is it.

How bad is it smoking? It could be a protective shipping coating or fingerprints burning off.

At a light i saw smoke coming from my pipes. But doesnt do it all the time could this be the tuner adding too much fuel. Maybe my head gasket going ?

If you now have no cats, and it is a little black smoke, that is normal.

a head gasket going bad would cause your engine to overheat, not blow smoke out the pipes. Now, bad valve seals, a intake manifold leaking coolant internally, or just the cats getting cristened could cause smoke. The air outside is getting colder and denser, causing cars to have the winter look already.

The car may be running real rich. Also, didn't the 99-02 Mustang GTs have a plastic / garbage intake? This may be the culprit...

Unless there is a real noticable about of smoke, I would not be to concerned. But then again, I have come to accept that Dodge/Ford/GMs have rattles, crickets, little ticking, squeaky pulleys, exhaust smells and some smoke.

a bad head gasket makes tons of white smoke, usually out just one tailpipe.


black smoke == fuel
blue smoke == oil
white smoke == antifreeze

all of those mixed together and ur looking at a motor rebuild!

i recharged the intake then broke one of the ends on the mass air. I installed a 2000 mass air. My year 2002 has an extra wire air tempuature sensor. I dont know if my mass air is adding too much fuel to compsiesate or something or maybe my tuner is too rich ? i smelled it today exhaust smells funny

Check out the physical intake on the motor itself, not the CAI. The physical intake is plastic. See if it is cracked and leaking anti-freeze. Is there any antifreeze smell?

typically cylinder pressure forces air into the cooling system, not coolant into the cylinder.

Check the oil and see if you have a milkshake. i.e. is your oil a white/yellow color? that indicates intermix with the oil and coolant and can be a good starting point for what to do next.

just had an oil change oil wasnt bad. I changed my mass air back to a 2002 mass air the connection is totally different. On the 2000 i have i should of just bought a new 2002 mass air when i broke it maybe haveing the wrong one made some problems

That extra wire is your air intake temperature sensor. It got incorporated into the maf in 02. You need to take care of that asap. Your motor is just guessing the air intake temp so it is adding fuel and pulling timing to keep things safe.

If you need a new sensor pm me. $88.00 for brand new and I can get my hands on a used one for you for $20

Also the 02 meter is calibrated for 21lb injectors(pink) and the 00 is calibrated to the 19 lb injectors(orangeish).

I was still typing this when you posted your previous response. Glad it's all worked out.
