my jeep will try to start but wont wait about 20-30 minutes and it will. it tries to start but acts like it isnt getting gas. have sprayed starter fluid into air filter and starts right up

What is your question?

if i drive it a couple miles no problems. but if it is over 10 miles distance it has to sit for awhile to start. Mechanic had it for over a week and never did it for him

What makes this problem better or worse?

after driven for several miles then try to start it after shutting it off

How long has your 2011 Jeep Liberty had this problem?

about a year
