Hello how is everybody?

I just purchased a lightning today. It is a 2000 with 30,000 miles. I have a couple of questions I was wondering if anybody could help me with.

First, the boost is reading past ten at WOT. The truck is supposed to be stock and it appears that way. Is it normal to read this much boost and is it going to hurt anything? I live in Iowa and the temp. is about 40 degrees.

Second, When I got the car the check engine light came on and two codes came up. First it said O2 sensor and the second said max boost or max speed. Then he cleared the codes out and said everything was fine, now the check engine light is back on. Any ideas what these can be? The truck runs real strong right now. I'm new to the Ford Lightning so I would appreciate any advice.

thanks skelly454

 

cold air is more dense and compresses better. so yes u will see an extra 1-2 PSI over stock in the cold weather. and yes O2 sensors go out fairly often
