I have a 2001 with the v-10. Recently it began to stall when going down the road particularly when encountering a bump but also on smooth roads. Have replaced the MAP, TPS. Do not want to start throwing money at it. It did not stall when at the shop for three weeks. It ran fine for a couple of weeks and then it began again. It is a standard trans and 4wd. Any direction would be greatly appreciated.

 

Have you checked the connections for things like the PCM?
Check connections on the Ignition control module, and the ignition coil packs.
Maybe ASD issue also.
A test light or multi meter are gonna come in handy..

 

Any luck with it?
my v10 runs funny, kinda like a slight missfire out the passenger side, kept putting in new plugs cuz that was the problem the first couple times, but now it does it no matter what, still halls *** on 40 inch michelins, but doesn't sound so hot, not sure what to look into,

 

i'd agree with what Veeten suggested, sounds to me like you have a loose connection, do you get the "no bus" on your speedo when it stalls?

 

40" michelins!!! holy cow, hope you changed your gearing!!! stock 3.55's and 40" tires are NOT a good combination.

 

I had a slight miss after I changed plugs.
The plugs ran too hot so I went back to the stock champions.

I also had new wires from autozone that one had a break between the wire and the little snap that clips onto the plug.
Took a couple of days to figure that one out..LOL
If it's you're CATS it will have the mother of all Ping.

 

Make sure the plug wires are routed properly. I've screwed it up before and had that stupid hesitation. I went from 8mm to 8.5mm and had to change the loom so that I could route them correctly.

 

I cant believe that missing the back loom for cyl 7 and 9 and the two wires touching made such a difference but it runs just fine now. I wonder if they were cross firing and the computer was protecting it. Thanks for the insight.
