Hi All-
Truck still misses and stalls after warm uo. what I've installed since july
* Dist cap and rotor
* plugs/wires
* 02 sensor
*PCV
*IACV
*New Coil
*Air charge sensor
* EGR
*TPS
*Map Sensor

Gonna put in a new dist pickup sensor today. The 02 was a cheap one, probably gonna get a good one. ANY recomendations on 02 sensor for this Truck? 1994 Dakota 5.2 l
thanks all

 

NTK or Denso only for the O2 sensor. These trucks really dislike bosch....

Have you reset the computer since changing all that??

 

Crap- Ordered the Bosch. Hopefully this will last at least long enough to see if it fixes the bucking /stalling after warm up. It runs great, till it hits temperature!! Also gonna put in new dist. pickup sensor. Anything else? If were the fuel pump, wouldn't it be crappy at all temps??

 

Return the Bosch. They go goofy out of the box. Go with the NTK (it's original equipment) or Denso as HY suggests. Many have gone down that rabbit hole before.

 

Ok will do. Ordered the denso, tomorrow arrival. This is so frustrating. thanks for the help

 

"This is so frustrating".

We agree!

 

Either way, gonna install new dist. pickup sensor. Hope it's not a clogged Cat. If so, can these be unclogged? It happens only after truck is heated up!

 

Get your current sensor soaking in PB Blaster right away. Soak it a couple times per day if you can. Prepare to use a box end wrench with a short cheater bar (due to limited clearance under the truck) to break it loose. This means you will have to cut the wires to get the box end on the sensor. There's not much room to work with but it is doable. Do not use an open end wrench on that sensor! Has to be a box end or you risk really making a mess of the job. You need maximum grip (all six sides) on that old sensor. Consider using the old sensor wire as a fish tape to run the new wire to the connector.

 

Once a cat gets clogged, that's it. It's junk. (for recycling... they are worth some good money.) There is no 'unclogging' them. Generally, they melt down..... and that's kinda hard to fix.

However, a clogged cat would give you issues right from startup. If it runs good until it warms up, that is either the O2 sensors, or a temp sensor that ain't accurate.

 

Thanks Hey you
Can ya tell a few of the temp sensors in these? I replaced the brass one on top of the manifold front. (air charge sensor)
thanks all!
