Vacuum hose busted

Vacuum hose going to the pvc valve was busted, but the car would run. Replaced the hose, and car will not idle, immediately dies. Put the old vacuum hose back on it, and will run. We also replaced the pvc valve but still will not idle. Any suggestions?

Sounds like the computer system readjusted it self to the specific air measurements that the busted hose was allowing in to the engine.(This is only relevant if you have a 1987-up) turn off the car, remove the battery cables, and let sit for 45 min, this is ample time to reset the computer memory. Reattatch cables and start. It may run rough for a few miles but if after say 50 miles of driving, if it still wont idle, than you may need to replace sensors. (MAF, intake sensors, O2 sensors, etc..)

Starts good wont idle stalls. if i give it a mid rpm will hold steady, let go of throttle runs rough and dies


Hi Russell:
I'd start by looking for a vacuum leak, often associated with the PVC valve. Make sure the PVC valve is not obstructed. Possible dirty air filter.
How long since regular Preventive maintenance was done?
Cheers

Why does my 2005 ford focus die while idling


Hi timberdwelle,

I believe you Ford dies while idling is because it's idle is too low, adjust the idling you will notice the change from the sound of the engine and base on the speedometer to see how high the needles goes up, don't go over 2 lines.

I hope this helps,

How to check pcv for vaccum leaks


The lines going to the PVC are what you would have to remove and check with a Vacuum pump or Vacuum source. Close off one end with your finger and apply Vacuum to the remaining end.
The engine and its cavities produce a Vacuum pressure when the engine is running to draw in vapors from the oil system. Therefore any hose connected directly to the PVC valve will vent through that system so you will need to test the parts off of the engine.
The PVC valve is a cheap part and usually does not break between replacement intervals. Because of the spring valve inside this part, it is to be replaced at intervals just like an air filter.

Rough idling/loping at idle it otherwise runs fine off idle.


1. Vacuum leakage Check throttle body and intake manifold for tightness. check all vacuum hoses.
2. Faulty fuel or pump or electrical.
3. Plugged PVC valve.
4. Air filter clogged
5. Leaking head gasket.
6. Camshaft lobs worn.
All of these porblems can cause lopes or erratic idle.

1994 gmc pickup- starts but when you put it in gear it dies, give it gas it will run but not good


It sound like your idle air control (IAC) valve is dirty and the fuel injectors. Try cleaning the throttle body and IAC with throttle body cleaner, if it's really bad you may have to use two cans of throttle body cleaner to make sure you have all of the carbon and varnish cleaned out. If this does not help, then there is a good chance that the IAC has gone bad and needs to be replaced but also check the wire harness to the IAC and TPS on the throttle body. Good luck and hope this helps and it would not hurt to replace the fuel filter also.

2001 ford escort, rough idle, runs smooth while driving, but tries to die at every stop-replaced vacuum lines, plugs, wires, etc.- nothing has worked


Your IAC may be defective, first check the canister purge valve by removing the large hose off the charcoal canster and plugging the hose with a bolt or something you can fit into it, then try it also check PCV valve and see if it's bad. there are more things to check like fuel filter fuel pump and or fuel strainer if fuel tank but would need to have more information to help.
