Hello, Having issues with my '01 Explorer 4WD, 4.0 V6 automatic. It started stalling a week ago, got off the interstate and made a right turn when it just quit with no warning. I put it in neutral and it started right back up. Drove another couple miles to work, came down a long, gradual hill to my job and it stalled again.It started right back up again. After work I had kinda forgot about it and left for home. Got to a red light where i sat for 6-7 minutes, light turned green and when I went to take off, it started sputtering and died. This time I had to sit there for 40-60 seconds before it would start again. Check engine light had already been on due to the speedometer not working, so when I got home I retrieved the codes.
Had P0171 and P0174 for lean condition left and right banks. So Far I've: Replaced the plugs and wires, replaced the fuel filter, tested fuel pressure- 60psi, cleaned the mass air flow sensor, checked the MAF voltages using 2000 StreetRod's write up. They checked fine, Replaced the IAC, Replaced a couple faulty vacuum hoses, Resealed upper and lower intake manifolds.
After all this it seemed to idle much smoother and lower and for a while I thought I had it fixed. But, next day it started stalling again. My questions are: could the lean codes cause a stalling issue? and what would you all reccomend my next move be?
Also, it was only stalling after sitting at a red light and taking off, or when coming off the throttle when going down a hill, or approaching a stop. Today however it quit while doing around 65mph down the highway. I was cruising along, went to accelerate, when it started acting up and wouldn't respond to throttle. I was able to coast to the shoulder where after 2-3 attempts it restarted and I made it to work.
I'm not gonna drive it again until I figure it out. I borrowed a nice Snap On scanner and will be working on it tonight. Just wondering again about the lean codes causing this.
One more thing, I just checked the codes again and only the P0174 is present.
Thanks for taking the time to read my post, and for any advice you may have.
