My 1996 dakota v6 would cut-out only after it got
hot. The computer (PCM) shut off all the fuel
injectors momentarily (0.1 sec) when accelerating
around 1800 rpm. After changing PCM, MAP sensor,
ignition coil and running many different tests to
isolate the problem with no success, I finally
replaced the timing chain and sprockets ($42 at
AutoZone). A lot of labor but no more cut-outs!!
The old chain had a little over 1/8 inch slop when
cold and I expect more when it was hot.

 

I would bet you haven't seen the last of that issue........

 

What makes you say that?

 

Because the timing chain is purely mechanical, and you have an electrical problem..... If, after replacing all those parts, it was still doing it, the problem is quite likely still there, just with the colder weather, whatever sensor isn't overheating quite so quickly.

 

I changed out the coil and ignition switch when I had those symptoms...

 

Even though the timing chain is purely mechanical, the cam and crank sensors convert the mechanical position to a precise electrical signal for use by the PCM. So far, the truck has been running great with the new timing chain and sprockets; no more cut-outs. I suspect the old timing chain/sprocket slop would momentarily cause cam/crank relationship (which controls fuel sync) to go beyond the limit that the PCM could correct for causing a momentary loss of fuel injector command.
Thanks for your response!

 

Good to hear a fix!!
