Any shop that will look at your vehicle will need to do a comprehensive diagnostics. An educated guess at what to look at is the idle air control valve. If that is receiving a signal but not responding, it may have gone bad and is in need of replacement. Before replacing, make sure that the passageway going to it is clear. Don't turn the plunger on the valve while it's off the throttle body.

Blue smoke


Blue smoke (how many miles on engine, 50k or 500K???????
to some this means, burning oil, others steam
it that blue smoke lingers a long time that is oil burning
and smells just like oil burning.
and means 2 things,
1: engine burns oil.
2: if car had autotmatic trans the vacuum modulator love fail
and suck ATF fluid to the intake plenum and burn it, and bingo burning oil like mad.
3: PCV valve packed solid,and forces engine to leak oil or burn oil. or both. this is a 50k miles service point, skipping this?
4: gas in the oil making it thin and not sneaks past valve stems.
does oil change cure this.>?

now engines.
worn out engines smoke. (burn oil)
as do bad valve guides and seals.
and bad piston rings.
100 years same story, and miles matter. History on engine too.
matters.

Excessive black smokw on start up when cold (2)low oil presure when hot


Slight engine wear. Would advise using a heavier oil. The 5w 30 is great with low mileage. As an engine wears & the miles add up the internal parts get looser & a heavier oil should be used to help. Would start using 40 weight oil. Some smoking will continue but you should see a decrease in the morning start up & a rise in pressure during the day. There's also the STP & other motor oil honey/additives that can help these symptoms.

2004 pontiac grand prix 71000 milesis burning oil. no leaks no smoke


How many miles do you go before you have to add oil. GM actually states that one quart of oil every 2000 miles is considered normal. I personally think that one quart every 3000 miles is normal esp at higher miles. As an engine wears things such as valve seals and rings get worn and allow oil to seep past and will burn, this can be in such small amounts that you will not notice the smoke and is normal engine wear. The life cycle of an engine is considered 100k miles by the designers, even though we all know they will go far beyond that. If your car has the 3.1 or the 3.4 liter engine you may want to check in the engine coolant for signs of oil, it is a common problem for the oil to seep into the cooling system but is not usually enough to make a noticable drop in oil level. If you are only using about one qt every 3k miles or so i would not worry about it if you have had it checked for leaks already.

04 Grand Prix oil leak


if it is not leaking then it is being burned by the engine, how many miles go by before you need to add oil?, if u are adding more than one quart every 1000 miles u have piston reing problems and or valve guide seal leaks. U won't see any smoke in most cases unless you are really going through the oil, like 1 quart every 300 miles.

Life expentancy of 1996 grand jeep cherokee engine


If the engine doesnt smoke to much and if you dont have to add much oil between oil changes and you cant hear any unusal noises from the engine you should be able to run that car for many more miles. My dad has a 92 Jeep Cherokee and he over 300,000 miles on it and it still goes as long as you take care of it with regular oil changes you should have no problems

you can pull the valve covers and inspect the rocker arms, but you may have a bad main or rod bearing. im leaning toward the main bearing being spun, at least.
