1999 Lincoln Navigator Q&A

1999 Lincoln Navigator Question: navigator shakes at stops and accelerations..

Coming into N.M. my check engine light turned on, there seem to be no issue, but wanted to check it out. I took it to goodyear in alburquere, did diagnostic and said they need to fix a small pvc valve on the vacuum hose and #2 spark plug and coil. the light went off..continueing towards Taos, my suv started to shake at stops and as i accelerate and sometimes as i go past a certain speed. Its worse than before i took it in to goodyear. In May 2010, i had a aurora goodyear shop fix all coils and plugs..would a plug/coil go out so soon? What could it be so i am aware of the next "diagnostic" test with another shop? -
Answer 1
Take the car to a Ford specialist who can diagnose your car. It's not uncommon for these vehicles to experience airflow sensor (MAF) problems. A good diagnostic technician should be able to help you.
