    Hello, my 1994 Jeep Grand Cherokee 5.2l has some issues, when I fire the Jeep up it stalls right away unless I’m on the gas and play with throttle a little then it will idle, have replaced TPS,Mass air flow sensor,Cleaned throttle body and the air sensor, also when I drive it get it up to around 1500/2000rpm and let off it stalls out on me, any help would be much appreciated!!

    It’s hard to say of course but I would make sure the throttle body is very clean because it will cause the exact problem you are describing with a dirty throttle body. If it is spotless the check base idle it should be 550 rpm with the iac blocked off. If it is not then adjust the idle screw as necessary. Also check for a huge vacuum leak just in case before making any adjustments.

    I have cleaned my throttle body very well with solvent, I will most definitely have to try the idle screw! Thank you for the response helps a bunch!
