Drove it and played with it a bit today so i can go get my pizza, heres the rundown, had a bunch of issues when i brought it out of storage, intake leak, fuel pump.running super lean, been chasing a rough idle for months, very little i get to mess with the car anymore, only driven it once this year new house and all, so few weeks back i put a air fuel ratio gauge in to try and help trace down my issues, messed with it today and it idles high and smooth for about 3 mins then as the idle comes down it starts getting rocky. As the idle smooths the a/f shows rich, 1 or 2 bars (autometer gauge) then as it comes down gets way down into the lean range then idle comes up and goes back to rich....unplugged the map and the idle smoothed, so shut it off cleared code and plugged back in, idle was smoother however when driving it it was dipping WAY down into the lean range to the point i had no lights, yet the cars not running super bad, just extremely low on power. Going to check the coolant temp sensor tomorrow when its cool, but everything i read the cars seem to go rich with the coolant temp bad, mines the opposite, any input, i'm just trying to get her running decent, in january i have to do emissions so all that stuffs gotta go back on and it will stay on since this is going to be my "emissions motor" Since i have a twin turbo LT4 in the works.
