PO403 Is rather generic. It simply means that the circuit has failed somehow. This means that the connector on your Exhaust Gas Recircultion sensor could have simple come off. I recommend that you take this to your Ford dealership. They can pin-point the prblem. They have to fix these types of problems for free for a certain amount of time and mileage. It is a government thing. Hope this helps.
Well it all depends on your liking personally i think a roush is much better than a saleen because the roush has a bigger engine most of the time i mean the roush has a 429 supercharged engine that is a beast of a car. So what ever you like but i like the ROUSH!!!!!!
The 427Roush mustang has 435 horsepower.The new 2010 Roush 540RH has 540bhp
It depends what customizations a person has made on their car, but a stage 3 Roush would destroy a GT. A GT (at least for 08) has a 4.6L engine and a Roush (428r) has a 4.6L engine along with the Roush Super Charger, Roush Suspension, Roush Breaking, as well as many other smaller differences. Overall a Roush is much better than a GT because what the Roush company does is purchase GT's and then upgrade a lot of it.
A Roush Sport comes in at around 36000 which is the entry level of the roush mustangs.
Mustang Roush is well known for designing the American Mustang car. He is the creator and designer of the all-American car and has made millions from the creation.
