I will try and check it this weekend. If not next weekend. I will be touch either way. Thanks again. I have a few other things that give my headaches. Not starting on really cold morning. It also idles rough when the engine is warm. Rpm drops to 600. Some autozone guy told me it was a master eng filter. Som name he calls tthis part that is screwed into the manfold. He told to clean it out every 5k.
