Answer
Hello there Ivan, sorry for the long delay i had to do some digging with your question. but i do have some places for you to investigate. Please check all your air intake systems for leaks. pcv valve inlet hoses vacuum lines ect. for cracks or damage repair or replace if necessary. Also check the intake manifold for leaks as well as your evap system for leaks as well. it is usually located under the hood with a green cap that heads to the fuel tank. We have a leak of some kind all that needs to happen is to find it. Brake Kleen or propane is also a another good way to locate a vacuum leak just please use caution when using either.

Anymore Questions Please give me a holler back
