Vehicle dies while driving-no acceleration possible

Have you checked the air filter?

two possible problems come to mind,,,
1.) idle air control valve (IAC) is restricted
2.) throttle position sensor is out of adjustment

to test the IAC, find a vacuum hose smaller than the size of a golf tee anywhere near the throttle body and unplug it....then start the vehicle. if the vehicle idles then replace theIAC

if this doesn't help see a technician that can diagnose the concern further and look at things like fuel trims, MAF values and BARO

This sounds like one of two things. Depending heavily on your vehicles milage, you could need a new EGR valve or a new timing chain/belt. Thank you, Dana

it is not rh defrost. sound like it is the tempeture sensor inop not telling the mass air flow sensor that vehicle is cold....

This is not necessarily an issue, but normal physics. I suggest remove your transducer and test with an external, known good, gauge.... Be sure the vehicle is at normal operating temprature....that will give the lowest pressure reading, as compared to cold engine.

If engine sounds okay, (when you accelerate, it revs up, etc.) then could be a transmission problem. (assume this is an automatic?)

Check fluid level first, if okay, next suggestion would be to change fluid & filter.

When you select a gear, do you get anything, any slight jolt to the vehicle?

If nothing at all, also might check the transmission lever linkage.

Is this 4WD or 2WD? If 4WD, also need to check transfer case setting, make sure it is properly set.

Get a code test done and see what you find...sounds like a bat throttle position sensor but without proper testing, I would not run out and buy one,

check the fuel pump fuse/relay, could be just bad enough to cause an intermittent start/no start. and check fuel pressure,spark and the crank position sensor.

Replace, or have the fuel filter replaced. Replace the air filter as well. If it still does it, have the fusable link(s) checked, as if the connection(s) is not secure, it will cause the vehicle to start sometimes, or die while driving. Also have a diagnostics done at your local mechanic, or a local automotive store (usually a free service; stores may vary)

if ur jeep has central lockin lock it and then unlock it ..........she might b sucking air inn
