1999 toyota camry v4 2.2 shuts off at idle
the car keeps shutting off at idle and only idle and we cannot figure out
also when the car is park, the rpms rev up on their own.
things we did..

-changed fuel pump
-unplugged small vacuum hose going to vacuum switching valve (VSV..next to air filter assembly under hood) and car ran fine, plugged it back into VSV and car would shutoff..so thinking that was the problem...replaced that. But now with new VSV car still shuts off..and once again we unplug the small vacuum hose going to it car runs fine.
- took big hose off of the throttle body where the air filter assembly is connected to and where the port was inside throttle body sprayed carberator cleaner down it to clean any gunk out.

PLease help anybody what can it be vacuum leaks? fuel injectors? what is It
also can anybody give me any tips on changing or cleaning vacuum lines and I've been also been watching youtube on how to check for vacuum leaks by spraying carburetor cleaner on the lines but if its sucking it in is that ok for the car?

 

Start by checking the complete length of the small vacuum hose you disconnected for cracks. It could the VSV is OK but the hose going to it has a leak.

And determine what part the hose runs to. The engine has several VSV's.

 

its the vsv next to the air filter assembly..where else are the vsv's at?

 

vsv are for the evap system got nothing to do with the idle at all , a torn hose will affect the idle , check the idle air control valve

 

does any know why my rpm's go up in park?

 

why it goes up? I think some really does goes up... but it's rare.

 

What is the idle RPM when in gear versus park?
