Po171 code came up on my 99 jeep grand Cherokee larado an the air bag light is on an the abs light how do I fix theses problems


First step is to look up Jeep trouble code PO171
This is the link I found:
http://engine-codes.com/p0171_jeep.html

I don't know about the airbag or abs lights. My old AMC concord used to light up all sorts of odd ball combinations of lights to signal stuff not related. You could look under your seat to see if any wire harnesses have come unplugged by stowing things under the seat but if nothing is hanging down obviously I would focus on the code PO171 first. Which as you can see has a lot of possible fuel and air type problems. It points you in the general direction. It is the actual behavior and performance of the engine that is your main concern. How is it running and is there any other symptoms or power loss you can feel and when? Have you done your regular maintenance and replaced your air filter or any recommended fuel filter changes from the owner's manual? If that stuff is done often the appropriate spray cleaner from the auto parts store can get things back without any repair at all. I sprayed one sensors harness with electronic cleaner and my code went away because oil and dirt from my smoky engine was blocking the signals.

Engine light on


Have if check engine light is on the unit scanned for a error code, most large auto parts stores will do this for free in hopes that if you need a part to fix that you will buy it from them, read the code and see what it means PO171 etc.

1997 buick lasabra engine code >po171


The trouble code is related to a lean engine fuel trim problem. This particular code can be caused by a vacuum leak, low fuel pressure or faulty MAF or MAP. Check for vacuum leaks first, if you cant find any broken or cracked hoses, you might want to take it to a good shop and have live data read to determine if there is a component defective.
