ok i am not sure if i post this here but any ways my 95 sport 3.9 stalls at a stop just replaced fuel pump runs better but when it gets warm it will stall starts right back up . and it doesnt do it all the time. no lights on {check engin} no vac leaks i can find fuel pressure is between 45 and 50 psi checked the wires under the fuse box by the bat they r good any suggestions?

 

Usually a stalling once warm issue is a bad oxygen sensor or coolant temp sensor. Did you check for any stored check engine light codes? The FAQ has a write up on how to do it along with the codes.

 

I put it on my scanner no coeds O2 sensor volts look ok but they do seem slow i used freeze frame to check when it stalled
coolant temp also looked ok. it is slowly getting worse ill replace the O2 sensor and give it a tune up let u know what happens thanks for your insight nice truck by the way

 

hey one more thing the IAT mod is it worth it for a daily driver?

 

sounds like an idle air control valve.

 

well mine does it sometimes, after i drive for a while and shut it off if i come back it wont wanna start, ill have to crank it over 3 or 4 times/ only happens once in a while. but its enough to get annoying and i just changed the IAC, Fuel Pump, plugs and wires.. so i dont know what itd be haha
