I have a 1999 Volvo S80. When I reset the computer and start it up, it idles fine, slight (I mean slight hesitation), but overall idles well. After taking it on the road then coming to a stop it begins to hesitate a lot and the exhaust starts to smell really rich. I get Codes P1171, P1174, and P0171...

I have also been reading that it could be a faulty/dirty ETM. Cleaning it seems like an easy DIY option. Could this be the culprit?

Juan, you have been very helpful through the process of fixing my car. I thought it might be the MAF. It was mentioned that if it was the MAF and it was idleing the way it is, that if I unplugged it and drove around I should notice a difference. I didn't. So, not sure if that means anything. What ty...

1999 Volvo s80 T6. Replaced CVVT, Coils, Plugs Cleaned MAF Searched for Air Leaks (Might be the problem?) Codes: P1171 Fuel Adaption Bank 1 P1174 Fuel Adaption Bank 1 P0171 Too Lean Bank 1 Exhaust smells really strong, stutters, surges, and gas mileage is half of what it should be. Any Suggestions? ...

Did you ever figure out what was troubling your volvo? I have a 1999 T6 S80 with the same codes. P1171 Bank 1 P1174 Bank 1 P0171 Bank 1 I was hoping I could deduce what is troubling my baby. She had a bad CVVT, I replaced it along with all 6 coils and new plugs. Then she ran great for 3 weeks. Then,...

I replaced a coil on the fourth cylinder and it stopped the misfiring, but it seems that the engine is not getting the proper mixture of fuel/air. I was told this could be caused by both the CVVT being stuck and a faulty O2 sensor. I'm going to replace the CVVT this week, clear the codes, and then s...

I have check engine codes on a 1999 volvo s80 t6: 1332 CVVT Solenoid 1132 Bank 1 o2 sensor Could one be causing the other? What should i replace first? Is the Bank 1 o2 sensor easy to replace? Can I do it myself? My car experiences hesitation when cold during acceleration and has acceleration surges...

Ok, so I have the codes down to two now. One is still the CVVT Solenoid P1332, I am going to replace this shortly. The other code that I have is 1132 Bank 1 O2 Sensor. My question is, could 1132 be caused by the CVVT solenoid being stuck? Is it possible that this code is registering based on the stu...

So, my 1999 Volvo S80 T6 has some issues. Just replaced the spark plugs and the fourth cylinder coil because I had a misfire in the fourth cylinder. Check engine light went off for about 30 miles then came back on. But the car was running a LOT better after the replaced coil and plugs. Now I get a p...
