I was on my way to school this morning, my truck just shut down. It turned off! This same thing happened this summer on a hot day (95+). Is this something I should worry about? Could it be bad gas (I use Mobil 1 (UDF) gasoline)? Dirty injectors? Airfilter? What could it be it's been worring me? I just spent $350 on getting my body fixed.

 

How fast were you going? Be honest.

 

Man, trucks and turning off at school.

I was just turning into my parking lot last week and mt truck stalled when i put it into nutural to roll into the spot.
I started it back up and it was fine.

 

^ YOU TOO!?!

I was going 25, 30 TOPS. A cop was behind me, I never speed near the school since I learned my lesson from that.

 

The truck doesn't shut down when you hit the governor, it just hesitates and won't go any faster.

 

Check your battery cables at both ends to make sure they're clean and tight.

 

mine has done the same thing 3 times now since i've owned it... itll happen at random times when im not doing anything weird or harsh or anything... never found out what it was.

 

What the f*ck? Recall?

 

Have you checked your battery cables??

 

^ seriously...

that sounds like what it might be...

battery cables. check first.

and if they seem good, twist em around a little.. i have to hit the ones of the f250 with a wrench to get the connection back, soemtimes...

 

Mine shut down on me and I hauled it back to a friends house in the middle of a thunderstorm. Checked the fuel pump emergency switch and it was tripped for some reason. Haven't had a problem with it since.

 

But you couldn't start yours back up? correct?

Mine shut off and I started it back up. I will check the battery terminals today.

 

Mine'll do it sometimes. I know mine is my IAC. My power accesories stay on, so its not the batt. If your stay on, it may be the problem. But I've had my old 93 4.0 stall out on me before when going from Reverse to drive, or vise-versa. A Computer hick-up is all I could think of... Good Luck!

 

yeah my lights and radio and everything else will stay on.. i know its not my terminals.. i thought it was my IAC valve too, but, it wasn't... i replaced it and it did it like 2 weeks after, so i gave up and now i simply ignore it, it doesnt happen often enough for me to care anymore.

 

Yeah I'm gonna check the terminals anyway, but my lights WERE on.

 

My truck did this exact thing too. But it would not come back on.... Turned out to be the Mass Airflow Sensor.... I was driving along probably about 15-20mph, then the engine just shut off... Could it be an intermittant problem with these sensors?? Of course mine wasn't intermittant, but with electronics anything is possible

 

I do have a k&n. and we know how much fine dirt they let pass.

 

Its not the fine dirt, its the oil getting on the sensors from the k&n..

Try cleaning your MAF for one, and check your IAC, it should be either of those.

My money is on the MAF

 

Ok how do I clean the MAF, I dont want to screw it up.
