Re: Good Knowledge about Tuning
a wide band is not a heated o2 sensor. a wideband is better used for tuning. The normal guy is Mark Roman but something about him not wanting to do OBD1 cars anymore. you can get a custom chip made. or you can buy a programmer to do it yourself. But if you dont have many mods a chip problem may not fix your problem. sounds more like a fuel problem like Traviz said. Maybe a couple bad injectors. check you fuel pressure, then with key off see how fast the pressure bleeds off, if it bleeds off really fast you probably have leaking injectors.

Re: Good Knowledge about Tuning
That is what someone else said about him not doing OBD1 cars anymore I dont know if its true. I never talked to him. But if you have his # you can call him. But if the car has a mechanical problem the tune is not going to take care of it. But if you can get some info. on it from him it might be beneficial to fixing your problem.

Re: Good Knowledge about Tuning
After looking at your other threads I dont think you need a "tune", seems you have something wrong with your car.
