i recently did the valve cover gaskets on my 85 monte carlo, since its been back the idle is arond 4 - 500 rmps. it would usually run at about 6 -700 rpms.
i also noticed when i have my foot on the gas and keep it there, the tach will go back and forth for about 200 rpms, it will pick up ok, then b sluggish, and so on.
i need to replace the cat, and its getting a tune up soon. i just wanna know whats going on with it.
thanks
