Thread: 2001 GTP surging / stumbling plus check engine light

I installed original OEM plugs and wires. No mention of a trans problem yet. Can I rule that out at this point? If ordering a new EGR, would you go with an aftermarket one or should I get an AC Delco one this time around?

Also, when I replaced the EGR originally due to the same code, the check engine light remained on even after resetting the codes. It wasn't until I had a battery issue that it went away. Is it standard practice to disconnect the battery after replacing an EGR valve? I read somewhere that closed position is not reset until the battery is disconnected.
