- '98 Mounty 4.0 SOHC 4x4
i have a vac gauge installed on my mounty, usually it reads like 18 hg but today i noticed it reading 20 at idol. i know it's within spec but it seems odd. so i came in and looked up some vacuum gauge diagnostics articles on google and did the 2,000 rpm test where you hold it at 2,000 rpm and check vac. it says it's supposed to be at 5 hg well i go do it and i get like 25 hg. if i gas it quick and hold it the needle goes way up to around 5 then slowly goes back up to 24 ish. whats going on? the idol has been feeling rough.
earlier today my belt came off and i was almost to where i had to be so i just kept driving. i went into job training and came out knowing i'd have to put the belt back on 2 hours later. i poped the hood and the radiator hoses were all suctioned flat and i had to remove the radiator cap and the hoses went back to normal. im assuming this is because the water pump wasnt going. but could driving without the belt on for about 2 miles in the city could have caused any problems?
