1997 Mercury Villager, possibly code p1179

Model: 1997 Mercury Villager Fault Code: P1179 Posted: 2018-11-03 09:58

I have a 1997 Mercury Villager Van that is throwing a code stating running lean on bank 1. It starts fine in the morning but will start chugging and sputtering and die followed with sometimes q popping sound. Once warmed up the van does great. I have noticed that sometimes I have no power when trying to accelerate sometimes. I just had the fuel injectors and spark plug wires replaced, the o2 sensor has been replaced and I have a fuel filter on way. It is becoming harder to start in the morning and keep running now that it's cold and I get an awful rich fuel smell. What could be causing all of this? I'm at a loss and dont have a lot of money to keep throwing at this van. I also have a check engine light on as well.

We can be more helpful if to post all codes rather than code descriptions. Also please post engine size and any recent work done.

I believe the code was p1179 I'm not sure though he just told me that it was running lean on bank 1. The fuel injectors have been replaced the spark plugs have been replaced the spark plug wires have been replaced I just pulled the mass airflow sensor off and cleaned it with a Q-tip and alcohol and had a little bit of carbon buildup on it and I have a gas filter on the way that I'm going to replace other than that I'm stumped as to why it's running so crappy it is the six cylinder motor

Without scan data (which you can get with a $5 app and $12 OBD2 adapter), and current fuel pressure readings (even though the pump is new), anything you try, or suggestions here, will either be lucky or wrong. Lean codes are often misdiagnosed by DIYers to the point that it would have been much cheaper to have it professionally diagnosed. I'm not saying that a DIYer can't diagnose a lean code, but in order to do so, they need to start with at least fuel trims at idle and under a load. Then depending on the outcome of that data, possibilities can be eliminated such as unmetered air, fuel delivery, fuel quality, or restricted fuel injectors etc., which each require a different test to aid in pinpointing the root cause.
