Very odd problem

Post by dumetre »

If I am cruising around for a while not really getting on the car when I pull the plugs the #1 cyc plug is completely black everywhere even the electrode while the other 3 cyc plugs all look the same and have almost no black on them. Today I warmed the car up put in new plugs and then ran through the gears WOT up to 3500ish rpm and shut it down. When I checked the plugs on that run they all looked exacly the same a nice even golden brown.

Here are a few datalogs of the car not sure which runs they are since I got them all mixed up on accident.

Not knowing what kind of injection setup you have , I'm going to guess that
you have 4 injectors setup for direct port injection .

If this is true , you have a bad injector .

If you can afford it , getting a flow matched , set of 4 new injectors will fix it .
