Just bought a 99 dodge durango its the slt 5.2 v8 has 129k

Drove it home and it did great tell i was pulling in my driveway it just died. Gas gauge is acting all funny and reads all over the place.. went to the gas station got 5 gallons and put in it so i no it has gas.. now everytime i start it, it runs fine for 5 maybe 10 mins then starts running rough and if i try to step on the gas to rev it it stalls and acts up only revs smooth if i ease into the throttle

Its as if as soon as it warms up it just dies

i cant even drive the thing for more then five min with out it dieing on me which is scary cause the ps and brakes get stiff




Can any one tell me whats wrong with it maybe and why it doesnt like to stay running when it is warmed up ...

thanks for your time

 

Fuel pump and coil are the first two things that come to mind, and I'd lean more toward the fuel pump. Check fuel pressure and report back.

 

How is the battery?

 

Battery is good cranks fine when it does die ... hmmm it revs fine when its cold so i dont think it is the fuel pump.. its only when it starts to warm up is when it starts acting up :/ maybe the comp or tps ughh :/ anybody else have this prob ?

 

It sounds like a sensor is going out... Do you have a check engine light or codes?

 

there was one but I unpluged my batt and it went away but still dies after 5 mins of start up :/

 

Just bought a new iac valve going to install that and clean my throttle body and see if that does it if not any more ideas? Thanks guys for your input

 

Iac valve didnt do it.. Did fine tell it hit about 200 degrees then would idle but as soon as I put my foot on the gas it wou like miss back fire and.smoke a lil ... Im stumped any ideas

 

Map sensor failed me too hmmm tps is good ... Maybe the pcm .. computer I heard 99 durangos are known for those going out ... Could this be my prob ? Thats a really spendy part to be playing the guessing game with

 

Sounds like a TPS to me. Also clean the Throttle Body and IAC and reset the PCM.
