3rd Gen Rams dies/ no codes

[TheVainOne]

Alright guys need some help. 2003 Dodge Ram 1500 4.7L dies randomly while driving/ at idol/ turning/ going in reverse. It's got 181k miles ( I know a lot) with no codes what so ever. Below is the list of stuff I had read could be the culprit that I've changed.

Tps sensor
Cam sensor
Crank sensor
02 sensor
Iac sensor
Cleaned TB
Checked all lines for vac leaks
Fuel pump/ filter
Plugs
Pcv valve
Map sensor
And in sure there is other things that I can remember. I''ve more or less been shot gunning parts since dodge won't look at it ( because I put aftermarket parts on there) and other shops say they don't have the equipment to diagnose the problem

Have you tested the battery? The other thing I would check is the catalytic converter. Tap it with a rubber mallet and if there is any rattling noise inside it's bad. What kind of mods have you done with the engine?

Pcm/ecu?

 

[TheVainOne]

I have done no mods to the engine. I had installed a cold air intake that I made but the problem was before that. I haven't checked the cad converter yet but I will give that a go. and pcm/ ecu would cause random dieing. After it tries to die it will rev to 1000 rpms and stay there for a brief time.

And the battery is brand new. The old one die about 3 months ago

Cat has a rattling sound and is Brown very Brown

Time to replace it or hack it off and have a chunk of pipe welded in. Likely the source of your problem.
