Problems with 95 Mustang

[crazy95horse]

Hey guys i'm having a problem with my car. The rpm arrow starts going up and down from 900-1300
rpm's after i turn it off and it wants to turn off. I give gas, but it doesn't get any.
Any suggestions!!!

what?

 

[2slo95fiveoh]

so when you turn the key OFF you car stays running, and the RPMs bounce around between 900-1300?

and start driving it starts doing that...

Sounds like you may have fuel pressure issues. Do you have a fuel pressure gauge that you could monitor when this occurs?

It's either fuel pressure like snakebit said OR it could be a vacuum leak of some sort.

Right now my car does the same shit and sometimes it will turn off after a hot start. I've found the problem and it happens to be a vacuum leak (Pretty big one too LOL)

no kidding! forget to blot down your intake manifold, or what? lol.

An easy way to check for a vacuum leak is to use a propane torch (do not light it) and move the torch around intake manifold surfaces while the car is idling. If the idle suddenly changes, you found your vacuum leak. The vacuum leak will suck-in the propane and slightly change the A/F ratio and cause an idle change. Hope this helps!!

Oh yeah......almost forgot. Make sure you are not smoking while doing this either. It could be hazardous to your health.

Usually I use carb or brake cleaner but i guess propane would work too? lol never tried it before..

LOLL that would be some funny ass shit.. i'll leave the details for another thread though.
