grounding question

ok my idle is shitty and my grounds need to be re-done. I searched but couldn't find a layout of all the grounds under the hood. should i run a single large gauge cable from the (-) terminal to the block? i also heard about running one to the coil pack mounts. are those ebay grounding kits any good? if so whats the basic setup of those?

No, no, no, no.

Custom is the way to be. It is a bunch cheaper, isn't ricey, and works better I bet too.

Running a ground to the coils is retarded. The ground for the ignitors is thru the units housing mounting nuts/studs to the chassis.

You said your idle was shitty. The grounds will probably help, but raggedy idle can be caused by a lot of things. If the grounds don't work
- Make sure TPS works and is adjusted within spec
- Clogged fuel filter?
- Idle speed set to spec
- Engine timing set to spec
- BAC valve clogged or not functioning within spec
- And finally, the worst one of all to detect and correct....vacuum leaks

If you're lucky, the grounds will fix your problem
