high idle issues

Is the TPS switch adjustable on your vehicle some of them are ? Also try removing positive battery terminal for 10 seconds then reinstall that may reset the computer.

agree with firebird, check tps. if its adjustable your prob is solved

Thanks for the responses. I tried removing the positive battery cable and it still does the still idles high so I think it may be something else that is wrong.

You may want to check your PVC hose for cracks or splits, especially where it connects to the intake manifold. On my 2004 ram 4.7 liter, the PVC connects at the oil filler cap, and to the intake manifold behind and below the carburetor, and it's a job getting to the fitting due to its location between the firewall and the back of the motor. When it's broken, the idle speed will generally run at near 1500 RPM.

GuruTNDKZ was right, thats what fixed my idle high problem

2005 ram 4.7 Starts and tachs out to th rev limiter on its own then dies. Throwing codes P2074 and P0508. Have already changed MAP and TPS

Cory im having this same issue someone please help. Dodge ram starts up tacks out then dies

I have an 07 dodge ram 1500 4.7L and every time I started the idle is up around 1300 or 1400 RPMs for about 30 to 40 seconds and then it drops down to normal I’ll only revs up to that when I first started no matter if it’s cold or hot have not figured out what it is I have replaced everything but the EGR valve can someone please help me thank you

Ok, after checking and/or replacing TPS, IAC, O2 sensors, EGR, PVC, I found the issue. The PVC vacuum line has a 90 deg boot on PVC valve a ABS plastic line, but the 90 deg 5/8 rubber boot that goes on too the back of the intake manifold (u can only see it underneath above on trans bellhousing). It dry rots and it a pain to change, long arms and small hands. I so happy to have solved this mystery after months of troubleshooting.
