Help with my 99 Dakota by hildyrox

Hey there! Before yesterday I have never had a problem with my truck. I have a 99 Dodge Dakota 2wd 5speed with the 3.9 V6 Magnum engine. Yesterday it Drove great. Until i let it sit for an hour or so then tried to go to my bank. I took off shifted into 2nd, it seemed to just lag. i didn't move my foot from the accelerator pedal, but it slowed down and the tach gauge would drop slightly. Let my foot off the gas and slammed it back down, it took off. Did the all the way up until the end of 4th gear. But If i hammer on it, and shift it at a higher RPM throughout the gears it seemed to not do it. I just don't know where to start!! Any ideas??

I have a 93 Dakota 3.9 with 104K miles on it . It will restart in the winter, but when it's hot, it won't restart until it has cooled down. Then it runs fine. This last time, I got a "check engine" light and pulled the codes. It had a # 22 code, (ECT sensor voltage too high). Could a bad sensor cause this non starting problem? Thanks in advance for any help.

i had the same problem for a year. it is definately the CPK, or crankshaft posioning sensor. they work by sensing a magnet on the crankshaft and sending the signal to the computer telling it when to fire.
 
it's sually by the bell-housing or on it. you can try to clean it, because grease build-up can block the magnetic signal. this might save you money and hassle.
 
the part has a square end on it, wipe that off good and then try it.

Thanks Herb for the info. I did change my coolant temperature sensor and that seems to have fixed the problem. Although, as all owners know, your vehicle loves to play little tricks on you and it may show up again. If it does, I will change the crankshaft positioning sensor as you suggested. Thanks again for the help.

97 Dakota SLT slows down on hills! by tfw3

I just picked up a project dakota to piddle with and here's question...
On level roads, everything seems to work just fine, however, when I travel up a hill, it slows down and doesnt get over 20 miles an hour. It acts like it has a governor system on it. The transmission seems to be shifting just fine and it doesnt seem to be slipping either.
My sister who is a mechanic says that it could be the passing gear...Would appreciate any ideas.
