Intermittent rough idle - ZR-1 Net Registry Forums

Billy Mild · 01-29-2016

It was 64 degrees here in KC, MO today. I decided to take the ZR-1 out to get a bath and stretch her legs a bit. The car ran great almost all day except when I went in the gym. I drove the car maybe 15 miles or 30 minutes. It was fully warmed up, stopped to workout for an hour. Then when I started the car it sorta ran rough and the idle was rough. When I gave it a rev it cleared up. This happened 2 more times on my way home. It is only around idle too.

I have replaced the coils, wires, and plugs(semi recently). Coils are less than a year old, wires/plugs are about 2 years old. I have replaced the injectors about 2 years ago with some Accell units that Haibeck recommends. I currently have 0 vacuum leaks.

Thoughts? Could it be tune related?
