P0171 is a fuel trim system lean (bank 1) trouble code, and it can be caused by an air or vacuum leak between the MAF (mass air flow sensor) and the throttle body, or a vacuum leak somewhere else, be sure to check all the vacuum lines and make sure all of the clamps are tight in the air induction system, especially between the MAF and the throttle body.

Po171


So all your saying is you never Googled the
OBD Code PO171 & have no idea what it is
or what to do
The fuel filter has no ties to any sensor & you change
it every 3 or 4 years
Any product you buy like injector cleaner is a waste,
16 oz in a 18 gallon tank of fuel. Ask yourself Diluted
like that, what would that do,ever see that recommended
buy any manufacture,nope
How about studying OBD Systems & get up to speed
What about the 171 code & changing front oxygen sensors
every 100,000 miles or component test yours,check for vacuum
leaks,smoke test the intake,check fuel trim,do something to actually find out why you have a fault code
Why has any time passed since the MIL lamp came on?
You diagnose all check light issues the next day, with any
vehicle problem,only been 30 years or more since we got
check lights on all vehicles

I have a 1998 dodge ram 4x4 with a 5.9, engine has been idleing rough, it idles fine for about 30 seconds then runs rough, almost to stalling, also the gas mileage is like 3 miles to the gallon. i had it...


If the speed sensor code is coming up change it. the sensor went out on my truck and it would die when i was slowing down and hit the clutch to downshift

1998 FORD CONTOUR CHECK ENGINE CODES P1131 AND PO171. REPLACED 1 OF THE OXYGEN SENSORS, CHANGED PLUGS, PLUG WIRES, OIL AND FILTER, ALSO REPLACED AIR FILTER AND CLEANED PCV FILTER, RESET PC AND IT RAN GOOD...


sounds like EGR valve and sensor this controls idle speed when at a stop. the po171 is a burn lean or rich code need to know what bank 1 or 2. also check for a vacuum leak from one of the hoses.

Service traction system, abs & tra off lights come on when you start car the service message goes off after a while. however the other two stat on. what is the problem?


There are wheel speed senors that tell the computer about wheel slippage. One or both are malfunctioning or the wiring is chaffed.

It shakes after i go over 75 mph but it shakes a little while im at a stop


if its after a particular speed, such as 75mph, rebalance all of the tires. if you have low profile tires and custom wheels you could opt for "road force" balancing which are going to reduce every possible flaw. nothing we do is perfect. we as techs are human and can only go off of the traing and experience we have obtained. pretty sure this will take care of it though. cheers
