I just replaced my headgaskets, water pump, thermostat, fan clutch, vacuum and water lines. Started right up when everything was back together. Idles fine but has no power and will not accelerate at all. I checked all the wires and lines that were replaced unhooked (had photos, paint and tape to help out with that. Any ideas or suggestions for a fix are appreciated.

 

Cam shaft position sensor (front cover area). Not the crank position sensor.

Throttle position sensor unplugged or bad. It will use a default value, can't keep up with real position of the butterfly valve in the throttle body. If you have a live data reading scanner it will show up as the TPS value, should change when gas pedal is pressed, minumum should not be zero, more like 9%.

Also may want to check fuel pressure at the passenger side rail, looking for 32-34 PSI.

Fuel pressure regulator has a six inch vacuum hose on driver side rear corner that needs to be plugged in.

Murphy's Law comes in a multi-volume set, hope it is something simple.

 

So it's not that vacuum line . . . Is there anyway without live data to test those sensors? Those things are pretty pricey.

 

Yes you can use a OBDII scanner to read live data and watch everything to see if they are working.

 

My scanner doesn't read live data. I was asking if there is a way to check the sensors without a live data scanner. Also now showing the misfire code.

 

I use the "ScanGaugeII". When the code is logged, it reads the freeze data, i.e. what was happening when the code was logged.
I also have the OT2 scanner.... Not much use, just good to show off to others. Even connecting the OT2 to the laptop is not much use unless you have a good software.

Still getting P1316 code after checking all vacuum lines and plug wires.

Ordered an Ultra gauge to read the live data.

Just to reiterate the truck drives fine until it warms up (heat hand in the middle) and it idles fine when warm. After warming it hesitates and will not accelerate at all. Has anyone else had this problem?

 

Where in TN?

 

I had a similar, intermittent issue. Started fine, drove fine...but about halfway to work would crap out and not let me go faster than 11-16mph, with hesitation and popping into the intake that resonated nicely into the snorkel. Ended up with P1316 pending codes on UG. New plugs and wires got rid of that code, but left me with a P0340/CMP sensor issue. Swapped camshaft position sensors and everything is right as rain.

Let us know what codes the UG shows you. Otherwise start trouble shooting like Savannah mentioned.

 

Ok. So I plugged in the ultra gauge and get a TPS value at idle of 3.92%. Also, now have a an alarm for cat bank 1 sensor 1 as well as the p1316 trouble code. So, I guess it's an oxygen sensor and a Throttle position sensor. Is there anyway to check the cam position sensor (before I order parts)?
