If I am running lean what are the steps I need to solve the problem. As far as I know this has never happened before. I came to this conclusion based on the appearance of the spark plugs and the readings of my g-tech. With ever run I am losing horsepower compared to the previous run. It seems as though the engine is running hotter than it should be causing a loss of power. Previously, I was able to make as many runs as I would like and come within 2-3 hp on ever run. Also, I have not switched intakes. The only thing I have done since this has happened is installed a suspension which involved unplugging a couple of wire harnesses above the front right shock.

 

if your plugs are white, then it's running lean.

I'd get an FPR and raise your fuel pressure. Another handy tool is an A/F gauge... get one, it's your friend...

Or you could just make sure you PLUGGED EVERYTHING BACK IN RIGHT.

 

yes, the plugs are white and I double checked the connections.

I thought a/f gauges weren't any good unless you had a wideband O2 sensor?
