74 Satellite with a 400 4 barrel. Has been idling right at 800 RPMs. Now its bouncing from 500-800. Whats the easiest things I should check and tweak first? Thanks.
Is the engine idle fluctuating wildly....or is it just needled bounce on your tachometer?74 Satellite with a 400 4 barrel. Has been idling right at 800 RPMs. Now its bouncing from 500-800. Whats the easiest things I should check and tweak first? Thanks.
Or an old one cracked...Yes, what have you touched recently. My first guess would be a vacuum leak somewhere, like maybe a small vacuum hose popped off
What else have you "touched?
Not likely. Carbs don't usually "un-adjust" themselvesHavent touched anything. Changed oil and filter last week. Have drove it twice since then with no problem till now. Ill start searching for vacuum leak, any chance carb needs adjusted? Thanks.
