last time full tuneup was done? and does it have an ac?

[pimpendacavi06]

its my grandmothers truck it only has 44,000 miles im just borrowing it i dont think anything major has been done to it as far as it comes to a tune up i know the oil is changed regularly though

Sounds like a vacuum leak.

Your right BlazerLT
It'll have to be a pretty big vacuum leak to be able to hear it inside the cab.

Very low mileage 89. I almost put that sort of mileage on every year
I wouldn't be suprised if the hoses have never been changed

iight guys thanks ill take your knowledge to the mechanic.... if it is that how much do u see it costing?

[dmbrisket 51]

just start the vehical and slowly spray carb and choke cleaner, when the idel changes you have found your leak, if the idel doesnt change you havnt, once you find the leak, replace that line, really shouldnt have to go to the machanic for it

[OverBoardProject]

What do you figure BlazerLT about $20.00 in hoses, and an hours wages?

You might need something like a PVC valve, or EGR which will cost you more.

dmbrisket 51 is right though. It's a job you can easily do yourself
