2004 Escalade stalling

These systems are very complex , you could have a short in the wiring somewhere to a sensor going bad or the switch for stability control could be bad . If you handy and know a little about automotive electrical systems you mite go http://www.alldate.com/ and spend $16.00 for repair information for a year . This is not like Haynes Manuals ,Haynes manuals just are not that good. Are any lights lit on the dash, abs , stability, check engine etc...

you need to scan the system for codes then you will know what area to look like wheel speed sensor etc

you may be looking at a bad throttle position sensor

Add some gas...
Sounds like your gauge could be broken.

Injector cleaner.... put in 2 or 3 bottles first.. if no luck..get the inectors flushed!!!

one or more of your sturst are going bad. you need to have your truck scanned. auto zone scans for free. they should be able to tell you which strut is bad.

try cleaning the egr valve maybe replacing it 2002 i dont think it would be your injectors or pump but there could be carbon built up in the egr valve so try that hope i was help.

Either the systems are inadvertly switched off or the system(s) is faulty. Sometimes a low battery charge may switch these off to preserve power and produce similar messages.

Given your high guage temps of 210 degrees and high ambient temperature of 100 degrees, your engine's stalling can very likely be linked to either one of these three causes: 1) vapor lock; 2) percolation; or 3) PCV malfunction. Here's a really good diagnostic article that precisely addresses this issue of yours:

Hope this helps! Brad

if it has over 40,000 miles on it change the drive belt and have the alternator tested and also make sure all of the vaccum lines are on and in place
