Hello everyone,

so my 97 12 valve runs great, except for one thing. At low RPMs if I suddenly stop or when switching to a different gear, the truck either almost dies, or it does die. Could it be the idle screw? It has a Suncoast transmission, timing advanced to 17 degrees, 100 fuel plate, boost elbow. thanks!

 

Very well could be, what's your idle speed?

 

In park it idles around 600 rpm, but when i shift it into revers the rpms drop to 500

 

Could be an issue. Idle should be 700-800 in gear with the a/c on.

 

How do I fix this? Is it mechanically difficult/expensive?

 

No, it's pretty simple. Here's a link.
