I have a 2004 Mercury Sable. Check Engine light code P0190

Question

Spark Plugs and ignition coil were changed which involved removing the intake. The next day the check engine light came on and the code is P0190. The car is driving fine except it seems like it\\'s using more gas. If the fuel pressure was not properly adjusted after the spark plugs were changed, could this be the problem?

Answer 1

Hi there,

This isn't adjustable, however if the fuel pressure regulator wasn't plugged back in you might see this code appear.
