Ok.... I bought this Explorer about 3 months ago. Its been running great.. once the weather started to get cold there would be some mornings that she would start right up, others not so much luck.
I started by replacing the IAC valve... problem still continued. She popped a check engine light .. codes 171 and 174. After the reading that I have done it seems that the SOHC 4.0 has a known problem with the intake gaskets. Tore her apart and replaced those.... checked all lines in the process to make sure there was no vacuum leaks. I used the Actron OBDII reader and reset the codes.
For the past 2 weeks she has been running great. Starts every time.... all the sudden today I get a call. Girlfriend is stuck... the Explorer wont start. Drove out and picked her up... tried for about 5 mins and no luck. Now I just got home from work. I went out and checked to make sure I could hear the fuel pump and she is making the noise she should be. Reach in and turn the key and she fires right up. No codes.... I need help badly on this.
What are the next steps I should try?
