Hello all-I have been reading here for several months but this is my first post.My truck is an 01 with 99200 miles and has had banks sixgun on it since about 66000.In the past week it has set a p1238 code twice and it sends the engine into limp mode.I took it to the dealer and they said not to worry about it.As you can see my warranty is about to run out,so any suggestions would be appreciated.Thanks in advance
