1999, 996, 117k miles Due to leaking I recently changed my coolant reservoir tank, which involved disconnecting and re connecting 2 fuel lines.. Upon restarting the car I had a rough idle and CEL. I purchased a $100b code reader, read a bunch of stuff online and decided to clean the MAF sensor, change the air filter, spark plugs, plug tubes and coils. upon today's startup I get an erratic/rough/low rpm idle, flashing CEL and the following codes: P0102 mass air flow circuit low P1319 misfire emission related P1318 misfire cylinder 6 emission related P1315 misfire cylinder 3 emission related P1313 misfire cylinder 1 emission related Somehow I went from a leaky tank to some bad stuff based on a do-it-myself moment. I wonder if the coil packs might not be perfectly seated? I'm thinking a new mass air flow sensor and all four O2 sensors need replacing?? Please advise. Hugo Kohl
