hi,
I've been out today in the 87 Gn, and its idling a little rough. Once checking through the SM, I could only find the crosscounts (CC) readout acting differently. Sometimes at idle it would just sit, sometimes the numbers would climb normally. Sometimes while cruising steady it would just sit, sometimes it would climb normally.
The IAC numbers occasionally show different behavior, but only at idle, and then it sometimes under 15, but also sometimes high at over 50 at idle.
My knowledge of Turbo Buicks has come entirely from this site, so my first feeling is that my O2 or wideband O2 sensors are functioning poorly, causing the rough idle. But as I am often wrong, I welcome to hear from you who have had similar symptoms and how you had resolved it.
Many thanks in advance.
Jim
