When I am driving car runs fine, but when I park and start to rev it is choking a lot (almost die on me)…It happens only 0-2000rmp, after that car runs good. When I rev it few times (5 times in 10 seconds) it also works fine, but when I will wait another 5 sec and then rev it hard is chocks again. When I rev it slowly its fine, only when I rev it hard it’s choking..Is that EGR valve???
Thanks for help

 

disconnect the vac line to it and plug it then take it for a ride.

 

I did that....The same problem...Maybe EGR is just clogged?? I have another EGR valve and I thing that I will replace it...Like I said before the problem occurs only when car stays still, when I drive everything seems to be okay...
Thanks
