I have read a lot of the threads about these two items. However, it is hard to to put all the info together because i get confused by the acronyms (DHP, PCM) and terminology. I have a 2002 Grand Prix GT. Common engine symptoms such as engine sputtering and loss of power when driving uphills or giving lots of gas is occurring and is getting worse everyday . Much of the solutions i have read are new plugs and wires, O2 sensors, and new Cat Converter. I already put new plugs and wires on. I have a buddy who says he can just gut the cat converter since a clogged cat is a common issue. Without going into detail on he does it, if he was to do that, would i even need to have 02 sensors? For legal reasons, i do not want to do this cause i'm not sure if Indiana has emission laws, but i really need to get this fixed asap. If this is not a good idea, then whats the best solution in dealing with clogged cats and O2 sensors. I would like to avoid buy a new cat converter since they are always getting clogged. Also I have no interest in adding any mods, i just want my grand prix run right. I am desperate for anyones help and i would greatly appreciate it. Thanks.
