i have an idleing problem my idle is all over the place sometimes its at 1500 then bounces then drops to 800 it and all over the place doesnt go past 1700 tho and it did it befor i got the intake manifold gasket replaced it stopped not its doing it again

 

Make sure that your tps is connected. My car did it when i forgot to reconnect mine.

 

do you know where the tps is located?

 

It's on the throttle body. There should be 2 electrical connectors. Make sure that they are both connected.

 

if the TPS is not connected u will get a check engine light right off the bat if u replaced the intake gasket and it went away for awhile then u have the same issue or another vac leak

 

yea my check engine light didnt come on is there an easy way to check or find the vacum leak

 

You can trying running the car and listening for it, but it will be difficult to hear over the motor, unless you know what it sounds like, a hiss. There are only a small amount of possibilities though. I suggest changing out your vacuum hoses. They're old and need to be changed anyway.
