Thefatmanwrx Posted May 13, 2018 Share Posted May 13, 2018 While having a spirited drive my cars eml started to flash i pulled over read the codes it was a misfire on cylinder 1 and 3 along with the p0113 and p0102 (maf and iat code) i cleared the codes and continued. replaced all 4 plugs to clear the misfire codes, but the p0113 and p0102 code returned i swaped the maf over with a known working one and still the issue only difference now is it doesn't do it every time I drive only under hard acceleration now and again. wireng fault maybe or has anyone seen this before and knows the anwser Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted May 13, 2018 Share Posted May 13, 2018 Cylinders 1 and 3 are both on the driver's side head so I'd probably look into inlet manifold / vac leak ,that the tgv's are operating ok and that earths, coilpack and injector plugs are making a good connection on the right hand side . Did you notice any colour difference between the spark plugs on each bank ? Hows the coolant levels ? Quote Link to comment Share on other sites More sharing options...
Thefatmanwrx Posted May 14, 2018 Author Share Posted May 14, 2018 Hi thanks for the reply the coolant level is full , and no all the old plugs look clean and identical, I'm starting to think it's wireing to the maf it's self the signal wire is my guess i used a multi meter on the maf plug where I receive 12v from the power supply and absolutely nothing from the signal wire it's self with ignition on where as I do get 5v from the iat signal wire. should i be receiving voltage from the signal wire is my question Quote Link to comment Share on other sites More sharing options...
