Maxed injectors I found that out the other day. As far as the lean spot either my tune is not right or my sensor is on its way out or I have a leak, but I think I fixed those. I am guessing MAF table and I am in the process of trying to fix it.

 

you could try bigger injectors to fix most of your problems

 

Ya I just need to find some 8.1's and get some money for them. It dont see much wot so that does not bug me nearly as much as the lean spots at part throttle.

 

Let us know if you find more info. Other than that green, the electrodes and insulators look normal but I'm not a builder or tuner.

 

My guess would be something in the gas that you're using...one of the additives, detergent, etc. (just a guess though)

 

Beats me has me all confused. O well I am going to get it running a little richer and see if they change. If not then it must be something in the fuel.
