i will tell you the whole story so please don'r be bored .
i bought my car one month ago . it is a mustang v6 2003
-i have changed the spark plugs.
-i changed the dynamo (alternator)
-i changed the engine belt the outer one.
after a week i installed new exghaust system .
i cut out the catalytic converters 4 of them and install staright pipes fromthe original headers to the new magna flow mufflers.
For the the first day car was g8 after that ithe service engine light cam on i have made my own MIL elimnator and fix them on the back two o2 sensors..
after that a NEW big problem came up with the car .
the thing is when i prees the fuel even if i am on the drive or N when the RPM REACH 3500 the car act like it was on 7500 rpm not 3500 like the 3500 became the maximum rounds for my engine...
i thought it was because of removing the cats.
but after checking the mechanic told me that i need a new computer fot my car ...
so please tell me is he right or i could try some thing else..
please hell my or guide me to the right way.
thanks alot
 
Did he scan it and test it to determine it's the computer? If he did he's probably right. If he puts one in and it doesn't fix it you don't have to pay him but if it does then you're set.
