 Subject: Engine dying momentarily @ hyway speeds
IP: Logged
Message:
Does anyone know what may be causing this problem. It's happened a couple of times. While driving on the Interstate, my rpms drop to almost 0 for a second or two, then come back up and everything is back to normal.
I've got a 98 Dakota, 5.2 V8, Auto, 4x4, ext-cab.
I would appreciate any insight.

first thing i would do is go to your local Auto Zone and have them pull the codes then report back what you find. sounds like possibly a dirty/loose/corroded connection somewhere.

my 02 does the same thing at 100mph. Does this happen at the same speed and rpm, If so I still could not tell you what the problem is.

I have a 5.2 that used to just up and die. I would notice the check engine light wouldn't come on with the key turned to on like it usually does just before starting it. So while the key was on I smacked the computer and it came on and started . So I unhooked the battery and pulled the plug w/about 60 wires out of the computer (I think that took a torx socket) Then I used electronic cleaner and sprayed it good. Well it would still take spells of dying or not starting without its smack till its now like yours just dies for a second or two at highway speeds. Usually @ 65 or 70. I wouldn't recommend smacking your computer as it could worsen the condition, but you might clean that connection

In response to ecdak, It's happened 3 sets of times on the highway, each going around 65mph. Not sure if the rpms were exactly 2000 each time. 2 of the times the it would happen twice within about 30 seconds.
Also, I had a friend put one of those aftermarket car computer code readers on the Dakota, and there were no errors stored.
I might have to stop by a Dodge dealer.

Mine is a 92 5.2 mag . It seems when this happens it is a loss of elec. power. LIke the asd relay is shutting it down ,but mine does give the code 12 . That the power to the pcm has been disconnected the battery and connections are in good shape . If I knew which pin in the connector supplies the power to the computer, I could check that connection a little better . If yours is not reading any codes maybe its the asd relay or its connections
Just my 2 cents

According to alldata, the PCM wiring is the same on the 3.9 and 5.2. I have a 95 3.9
PIN function circuit
51 asd relay control K51 / 20DB/YL
57 asd relay output A142 / 16DG/OR
looking into the connector, black on top , pin 1 top left. middle top is pin 21 and right top is pin 41.
worth spending the $24.95 for alldata.

Yeah it's all online, not downloadable. The wiring diagrams are really nice.
First vehicle is 24.95, second is like 14.95. It's Make/model specific. I have a 95 3.9L 4x4.

Here's one a those tricks we don't think of > Take one of those small cheap timing lights and hook it to any spark plug wire > run it between the hood and forewall and tap it to your driverside wiper so your pretty much looking right at it > Now take your normal next highway trip > When it happens if it's ignition the light will stop working > If it don't it's some sort a fuel problem > Now you got a much better idea where to be looking >oh > I bought my cheapy in a garage sale foe 50 cents lol

more info on pins for Mine too
PIN function circuit
51 asd relay control K51 / 20DB/YL
57 asd relay output A142 / 16DG/OR
k = PCM
A = battery feed
k51 is 20 guage wire, dark blue with yellow tracer
A142 is 16 guage wire, dark green with orange tracer

so what's the verdict. Did you get it fixed? I hope you can fix it w/o going to the dealer. who needs a whole day of hassle and expense like that. When I would hit my gov at 100mph it would shut down until 95 and come back on again. being that you have a 98 that is a 7 year old set up that just might only need some minor help and maintence.

ecdak, no I haven't got it fixed. I'm going to let it happen again, and use a code checker thingamagigg to see if it'll tell me anything. If that doesn't work, I'm gonna do some soul-searching and decide if I want to spend serious money on letting a dealer look at it, or just let it ride until it breaks and eliminate any mystery. In the mean time, I may try some of the tricks suggested on this thread. If I do figure it out, I'll post it. Thanks.
