i have the stock o2s in it and they all throw codes. i am waiting for my mechanic to get a new program system to remap and he is going to delete the need for the o2 sensors. i dont plan on any paint or body work for a while. i want to get my suspension first, then i will work on engine, i.e. 3.8l crank, 272 cams, lighter fly, and sport pulleys and gears. after i am satisfied with that then i will save up and re do the whole car to the original paint. i have a dent on the driver rear fender and a bunch of little dents and dings all along the fenders. the total cost for body work and paint for my car is just around $2,400.
