Hey everybody new to the forum, well i purchased my 2000 4.7 dak a few months back. The previous owner had told me something electrical needed to be replaced i cant think of it at the moment but it was a cheap part when i looked it up (ill edit the thread once i find out the part again) but totally forgot to replace it up until now. The truck has been acting strange the last 2 months, it has no problem starting and going for a long drive but lets say i go for a 30 min drive shut it off and then 5 to 10 mins later try to start it, it will cut off instantly and putts out. only after a little bit of resting will it cut back on and sometimes i have to feed the pedal to get the rpms going high enough for it to maintain the idle. That's just one issue another issue that was happening at the same time was overheating and my voltage meter going over as well, my fan works, previous owner had just replaced the radiator, and i had coolant. Also my dash where my gear indication is at sometimes isn't on when i start the truck but some days will be. So hopefully you guys can help me out and tell me where to start, Could it be an electrical issue ? could it be affecting the sensors thats putting up those codes? and is that causing the overheating? Any and all help is much appreciated not a mechanic here so help is much needed lol thanks again!

 

Welcome to the forum.

What part???

P0130 1/1 O2 Sensor Heater Circuit Malfunction
P0136 1/2 O2 Sensor Heater Circuit Malfunction
P0152 2/1 O2 Sensor Shorted To Voltage
P0158 2/2 O2 Sensor Shorted To Voltage

I'd start by crawling under the truck and checking the harness to each of the 4 oxygen sensors. It could be damaged, maybe it dropped onto the exhaust system and melted, or got caught on something.
For the cluster problem, do a cluster self test and tell us the results. With the truck OFF press and hold the trip reset button. While holding it down, turn the key to ON, don't start the truck. Keep holding until CHEC appears in the odometer window. If it comes up with a 3 digit number, that's a fault. The cluster could be bad.
It also could be a bad ground.
On the overheating, is it actually getting hot or is it a temp gauge problem?
