Fix the misfire concern on cylinders 5 and 6. That will probably take care of the lean codes p0171 and p0174. The catalytic converter is probably damaged from the misfire concern....that's what is setting the p0420 code. Take care of these concerns first before fixing p1131 code

Why is my Lincoln LS V8 2002 has the ABS and Traction Control light on?


The traction control works off the ABS system You will need a scan tool capable of reading ABS codes before you can further diagnose the problem If you are able to retrive the abs codes searrch on the internet for the trouble code Many times it is a wheel sensor or bad connection on the sensors .

Po304 po307, i think my engine coils keep going out i also have a po420 code


You may have 1 bad coil not both #3 & & #7

You also have a bad exhaust converter from 10
years of on & off misfires

The PO420 is (Bank 1) Passenger side

Fix the misfires

Replace both Converters

Replace all 4 O2 Sensors

Converters should have lasted a few more years

A cop ignition coil is $59.00 & takes about 15 min to put in

No reason to pay someone $500.00

2000 Lincoln Ls V8 still getting code PO420 after replaceing Cat Conv,changed 02 sensors, still getting code PO420 and now when exiting the freeway the car turns off.... have to put it in park to restart...


Check your MAF sensor readings. ( MASS AIR FLOW ). You probably need to clean out your throttle body. If it's not reading properly, it could def. kill your car. Hope this helps, James Booth. Please rate this. :))

2002 lincoln ls cutting out real bad and engine light on


The engine light on means there is a trouble code waiting in the cars computer memory to be read. major auto parts stores have code readers and will read out the code for free. This is the place to start the trouble shooting process.

I have a 2002 f150 4.6 codes p1131-p1151-po316-po306 runs bad under 1000 rpms wont idle going down road stumbles at steady 45 mph not sure what to do next what do u think


p0306 is a cyl #6 misfire
p0316 is unknown to me. sry.
p1131 and p1151 deal with the O2 sensors 1151 says Bank 2 Sensor #1 Heater Circuit intermittent. 1131 says that HO2S 11 indicates lean.

p0306. Check the plugs wires and coil at Cyl #6 (second one back from front on drivers side, if it's the same as my Stang)

Truck misses after it is warmed up.


Start with a tune up, spark plugs, spark plug wires, fuel filter, air filter and that might cure the PO300B code, hope this helps, Gary
