You guys have any suggestions on how to lower the idle on my 87 burban 350 with EFI. She has a crate 350 in her. She idles high and it sounds rough on the trans when i switch into reverse. Also is killing my gas mileage, she will coast on her own in Drive without depressing the accelerator.
Also anyone know how rare it is to have a burban with manual roll up windows?

Thanks,
Dave

i cant help ya on the idle issue but the manual windows are not that common but they are out there. My 93 has manual windows. it all depends on what body trim you have.

Most likely a bad idle control valve. See them here at racepages. A faulty unit will cause high or low idle issues. You can't 'set' the idle like you can on an carb. They look like this. Good news is they are under $50.
