Question about 2003 Cadillac CTS
Check the timing belt and related parts. One cam sprocket off time will cause this condition with codes for random misfire and 1 3 5 misfire or 2 4 6 depending on which side.

Mine is doing same thing and saying cylinders 1,3,5 are misfiring. Idles rough as well. Now it started occasionally saying engine power reduced and won't let me accelerate. I can tell when it is going to do it because the transmission shifts very rough. Any suggestions?? Thanks
