My first problem is my truck dies randomly, doesnt hesitate just like i turned the key to off. It starts right back up no problem, no ce light either. I'm thinking its either my IAC or CPS. Do yal have any other ideas?

Second is after work i get in my truck and my raido wont come on unless I turn the truck off then back on. the if i hit clock it wil show the time and that just goes away after a couple seconds.

Both have happened twice in the last two days.

Thanks

Huh my 05 grand cherokee 4.7 did both things too never figured them out befor i totaled it good luck.

 

i sound like a broken record, but make sure you have good connections on your battery. These trucks don't like bad grounds. One of these times someone is gonna come back and say "Hey, that was it!". That's why I keep saying it...lol

 

just curious but what all did you try?

 

For the engine stalling, you can take it to the dealer for an update on the PCM and that should fix it.

 

Have you reset your computer? I did then I had the same problem. I did a search and found this, the best part is it really works. My truck runs much better and has not stalled in weeks.

Stalling / idle problem fixed
I'm starting a new thread since this is apparently such a common problem on our trucks and someone will undoubtedly need to search in the future.

As a recap, I replaced the clutch hydraulics on my '05 V8 6sp and then had a stalling issue. The problem had never existed before the clutch fix and all I had done that may have affected idle was disconnect the battery and the two main harness connectors by the breaker box. No codes were stored except one for low idle which was obviously a RESULT of the problem and not a cause. So anyway...

After much reading here and elsewhere (thanks everyone), I decided that cleaning the IAC and throttle body couldn't hurt and was probably due anyway with 94,000 miles. I disassembled and cleaned the TB and the IAC which was filthy! The rubber plunger and seat were obviously not sealing properly. I cleaned it all out with sensor cleaner, lubed the orings and reinstalled. Not only is the stalling issue gone, but the idle is now rock-steady at 700 and I have power back that I didn't even realize was gone! It's like a different truck I swear. As y'all may recall, I had said the clutch felt grabby and not as smooth as before and even that's better now that the engine is running more smoothly. My theory is that, over time, the PCM adjusted/adapted to the dirty intake components and so no problem was obvious. Upon reset though (disconnecting the battery) the PCM "forgot" what it had been doing and could no longer cope with the dirty IAC and TB. Lesson learned! As others pile up the miles on their trucks, I'm sure this will happen again so I hope this helps someone in the future.

i plan on pulling the iac out for a good once over tomorrow. I'm assuming its the problem cause i have had the same problem on my old heep.

 

take some pics along the way. I'm sure I could find the iac, but it would be easier if I had a picture to go by, how to remove it, what to clean it with, etc....

 

Check to ensure all of your ignition fuses are properly seated. If you have one loose or making partial contact the vehicle will die just like turning the key off.
