After putting a de cat pipe on a month ago my engine management light came on 100 or so miles later,2 days later 1 of the ignition coils blew,so i changed all 4 and all 4 plugs.a week later another coil blew,so i changed that,i also plugged in the vag com which said the lambor sensor was duff,so i put that down to the decat.and the temp sender was duff too,so i replaced that and had the em light turned off,Problem solved!! No! the em light has come back on 2day so im expecting 1 of the coils to go again in the next few days,has any1 else had this problem when using a decat? the car also has the following mods, revo sps 3,baily dumpvalve,pipercross inductionkit. new coils on order again!!
