greddy turbo kit users with CEL
 

i have the greddy turbo kit and i recently had my CEL codes scanned and they were......
P0037
O2 sensor heater circuit low-12

P0102
MAF input lower than expected

p0302
cylinder 2 misfire

which of these are normal for the greddy kit to cause? i kno that after intalling the greddy turbo kit that it cause the CEL to come on. ive done searches as well and as far as the misfire im replacing the coils with new OEM ones......i really wanted the Ignition Solution but at 600.00 im going to wait and go with the stock ones for now
