Re: need help with codes

Both of your p0171 and 0174 would indicate a lean condition. I would start out by checking for vacuum leak under the hood. If no obvious leaks are found I would get a fuel pressure gauge from a loan-a-tool program at your local parts store. Test the fuel pressure engine running 30-44psi, key on engine off 34-44psi.

Your ABS codes are more then likley your ABS module.

Re: need help with codes

Have someone check for service bullitens on your codes. Very common problem is upper intake manifold leaks. They use rubber gaskets that leak during warmup causing a lean condition but seal up when the engine is fully warm making diagnosis difficult.

Re: need help with codes

Hello,
We have a 2000 Lincoln LS w/ a 3.9. The temp gauge went to H and we pulled into Autozone. The car cooled down and the guy said it was a 1229 code. Is this anything that you have heard of. He said that it could be air in the coolant lines or maybe a thermostat. He didn't have a clue nor do I. Can you kind of give me a little information on this. Is it common in the 3.9 Lincoln motor?
I really appreciate any help!
