yes, if you have installed a new cam, then you'll need the computer reporgrammed. we can do a basic tune to get the car close enough to start and drive assuming the work was done correctly and there are no other issues with the car.

feel free to give us a call to set it up.

Like Bryan said, it needs a tune b/c of the hotter camshaft.

As far as a throttle cable, look through the classifieds and find someone parting out one of these cars and get one from them. You could also try a locla junkyard if you have one nearby.
