Car not running, HELP

[TBapp3]

I don't know whats up with my stang fellas hopefully someone knows....

I go to start it up (it has been sitting for a week) it fires up then idles down very low and stalls ... So I then try again and it idles down again so I gave it some gas a quick rev to 2k rpm s and it idles down again to about 300 rpms about to stall but goes back up to about 800 and back down then stalls.... I start it again and then realize well it's revving around all low the oil pressure Gage dropped to zero.... I shut her down and checked the oil witch is still good



Some one help!!

try checking the spark plugs

Does the car maintain rpm's if you hold the gas pedal steady at a slightly elivated rpm? if it does and the only issue is that it wont idle I would think you have a bad IAC valve.

 

[eddie]

is your check engine light on

Mouse nest in the airbox? Fuel pressure?

 

[TBapp3]

No light and yes I could hold it at a sertan rpm if I wanted but it didn't seem right as i never touch the gas pedal when I start it till it warms up about ten mins

​

 

[TBapp3]

Not sure on the fuel pressure I was only there quick I gotta check it out more tomorrow nut any advice is appreciated!!!!

What I am saying is that at an idle the throttle plate is closed and your idle air control valve opens to allow the engine to run. If that is not working then your engine will stall at an idle. Usually you can narrow down this problem by holding the rpms above idle. If the car doesn't stall then that is probibly the problem. You can pop it off and try cleaning it with throttle body cleaner. Some times they stick because they build up gunk.

+1 on the iac.

So war do you guys think about the oil pressure gauge dropping????

​

 

[TBapp3]

I started it up again this morning and it fired up idled down low the same way again for a second then reved up to about 1100 rpms as usuall when not warmed up but I sat there in the car and the oil pressure gauge dropped again I touched the gas and it whent right back to the middle where it should be.... This happened a few times well sitting there for about ten mins then I just

[TBapp3]

Shut her down... Sorry for any mid spelled I'm on a phone

[TBapp3]

Thank you I will check this out as well

Could be an oil pump issue but only real way to tell, is if you put a real oil pressure guage on it, not sure how much to trust the factory gages and what the actual pressure is, low, middle, high, you get my drift.

​

 

[ambers03sixxer]

Yup that's what I was thinking....I have a friend coming over to test the pressure tomorrow Ill post back from there

Thanks

Have you scanned the car for codes Todd??

 

[TBapp3]

I have not Tim but there are no lights on..... So the guy I thought wAs checking my oil pumP is a fool and now I'm stumped is there something I may be able to rent from aa or something to do this????

Just because there is no light does not mean there are no codes...

As far as checking the psi of the oil pump not really. It has an electronic pressure sensor on it. I think it is near the bellhousing on the back of the motor on that car. Check the harness and make sure that it is in good shape. New ones should be pretty cheap. Might be worth just changing the sensor.

the oil pressure switch is right above the oil filter. hook up the mechanical guage there
