01 s80, shuttering flashing CEL
Car started shuttering and flashing a CEL on my way home the other day. Swapped all the plugs, got the following codes P1171 p0455 p01132 p0301
p0301 is a cylinder one misfire so I swapped the coils to see if I could get a misfire code on a diffrent cylinder to be able to determine if it was the coil. Still the same code. Trying to get to the bottom of this, please help

your happy meal of codes add up to 1171 fuel trim (running lean or rich), 0455 evap system, 1132 front O2 sensor out of range and 0301 misfire on #1. My first step would be to look for an intake air leak - probably starting with the J hose back by the Evap cannister, then working my way through the vacuum lines, intake air hoses and the like that come off the Evap system. The codes are saying the O2 sensor can't compensate enough for the air being metered incorrectly and as a result #1 is the first to misfire. If nothing is obvious then you may want to clean the intake - ie MAF, idle air valve, throttle body but my bet is you have an air leak associated with the EVAP system.
