why wont my truck idle?

Check for vacume leak, around intake,and your cruze control module.

we have also done that there are none

Have you tried cleaning the throttle plate and assembly?

yes we have

The idle issue would lean toward vacume loss,along with cruze not working,And you replaced the sensor on the AIC,did you remove and clean it all so?

could it be in the computer we have checked all wiring and plugs fuses battery

If truck crank,s the Ecm should be fine,in my experience ,there is a vacume leak in the system,you can have a vacume test done to rule it out,but from what you have discribed,i think that is the issue,dont just check under hood,it could be at the tranny.

ok I will check that I really do appreciate it thank you hope I can find something out in the morning I will let you know

I’m having the same problem with my 99 just not the Cruise control. What do you mean by vacuum is that the air intake ?
