hey guys i was wondering if its normal for my cars idle and oil pressure to go up and down after a few mins when the car starts to warm up.. i looked at the treads but no luck.. it goes to up and down between 60 to 20.. so just wondering if thats normal. thanks

is your RPM going up and down at the same time as the oil pressure, if so its probly a vaccume leak or radiator needs to be blead.

 

thanks ill check both and ill let u know...
