Hello all. I'm new here but I have a question. I have a 2003 Dodge Ram 1500 4.7l. 181k miles. I no boat load of miles. The trucks stalls and idles like crap at about 500 Rpms. Gives no warning when it's going to die it just does. I've done everything I have read on almost every forum. Here's what I've done so far.

Camshaft sensor
Crankshaft sensor
Tps sensor x2
Iac sensor
O2 sensors
Cleaned TB
Replaced fuel pump/filter
Map sensor


I'm completely at a loss right now. Any help would be awesome. Thanks in advance

Check all grounds, vacuum hoses, even see if you can bypass cat converter. Plugged cats can cause a big headache. Can't believe dealer can't pull up a code. Every time I've had a problem, with an old Jeep, like that, the dealer found the fault instantly. Luckily, my hemis have been trouble free.
