WARNING: This page is about a different car, the 2002 Pontiac Sunfire, 2002 Pontiac Grand Am, 2002 Oldsmobile Alero, and 2002 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
DTC P0130 or a slow response is most likely caused by HO2S 1 contamination. Inspect HO2S 1 for silicone contamination from fuel or use of improper RTV sealant. The HO2S 1 sensor may have a White powdery coating, which will result in a high but false voltage signal indicative of rich exhaust. The PCM will then reduce amount of fuel delivered to engine, and cause a severe surge or driveability problem.
