Just completed my head gasket job, replaced the valve springs, rocker assembly, valves, lifters, remanufactured injectors (Bosch Gen 3 19 lbs), oil pressure sensor, fuel filter, new Champion Spark Plugs, and replaced the seal for the front timing cover on my ?96 D1. Sparkplug wires are original Magnecor. After putting it all back together and driving it down the street, my check engine light came on. I pulled the following codes:
P1316 (Misfire Causing Excessive Emissions)
P0300 (Random Misfire Detected)
P0303 (Cylinder 3 Misfire Detected)
P1191 (Downstream Heater ? Harware Driver O/C (both heaters)
P1314 (Misfire Likely To Damage Catalyst, Bank B)
Engine ran fine before the head gasket job (just leaked like a sieve) and the fuel pump is relatively new. Idles fine. Any thoughts on how I would troubleshoot and correct the problems?
