I am posting this for a friend since he has tried other boards and had no luck in solving this. The car a 97 V6 Camaro (silver in color if that helps
has a stumbling problem that occurs at about 3/4 throttle. He has replaced the coil packs (3) plugs & wires & O2 sensor twice. It doesnt happen all the time, but last time it did the ECM had stored these codes:
These are the codes that came up on the scanner last week. The O2 sensor
thing has been coming on and off for the last year and a half. I changed the O2
sensor but it didn't help. I don't know what the other one could be.

Anyone know what the p1441 code means? I wouldnt think the o2 would cause stumbling unless its running rich. Any info would be appreciated.
