I have a 1998 dodge dakota, standard, 5.2 magnum. Just started while driving it stalls/bucks/missing, choose one. It only hestitates briefly for a couple of seconds. Not always.

I have changed the plugs, plug wires,coil, rotor and cap, TPS sensor. All have not fixed the problem. I also checked for vacumm leaks none.

Any idea what is wrong.

bad coil possibly

 

Coil. Or,.. Cam-sensor?

 

or pcm safe symptoms mine had when the computer was shot

 

Thanks, I will look at the cam sensor, it has a new coil just installed.

 

very cool, a 5.2 magnum. I have a 2.5 magnum, 4 cylinder..

all i can say is, if none of the above has worked and your check engine light is on, try getting it scanned by Auto Zone or even local mechanic places. they should not charge a lot of money.

 

look down the throttle body and see if theres oil in your intake, a bad plenum gasket could cause some of those problems. could also be a timing chain problem.

 

it could also be a bad O2 sensor. I had a 93 geo storm that had these symptoms when it was cold. Once it was warmed up it was fine but it was a bad o2 sensor.

 

autozone reads code around here for free......also could be that your cat is starting to clog up.

 

I did some testing on the cam sensor and I am supposed to get 5 volts, testing the connector coming from the PCM. I disconnected the connector and just tested the wire coming from the PCM, I have 5 volts both wires. The test is supposed to be with the wire connected back probe the wire and you are supposed to get 5 volts off and on while cranking the engine.

I get a constant 5 volts even with the connector disconnected. Why ? I do not have a Autozone near me.
