Do a search for "idle hunting." You'll get some answers. I had a similar problem. I replaced the O2 sensor, the head temp sensor and the idle control valve, but nothing helped. Then someone suggested mixture. I had my mechanic tweek the mixture...problem solved. Sometimes the simplest solutions are the best.

Thanks Scott. I did find a ton of info on this on the website. Great stuff! It started right up this morning and is idling well so far, after setting the mixture last night.

Thanks again,

I use my propane tourch to light the charcoal for the Bar B Que.
