PLEASE HELP........First off thank you very much for reading, I’m so desperate...

For the past year my cars idle is terrible, it coughs and chugs until the warm up period is done, it’s the worst in wet damp weather, especially rainy days, it will stall at almost every stop light.. In cold weather the car is fantastic, no stalling smooth start, summer spring and fall is not so good at all... I’ve read forums on every web site I can find, so I am very aware of all the issues associated with the symptoms.. I’m listing below all the parts I’ve changed so far and a revelation I discovered by accident, I cleaned out my ETM and the car ran great for a week then back to its symptoms. So I did it again and it ran great for another week or so, then back stalling and rough idle again, It hit me that every time I disconnected the battery and reconnected it the car ran great! All banks running evenly, when the car’s not running well Bank one is NOT.. I’m listing below what has been changed thus far, by my Volvo mechanic, oh one more thing, no codes are coming up! Just makes no sense as to why I disconnect the battery and reconnect and it runs great.. I no longer own this car... It owns me!

NEW ETM and Flash—MAF—PCV—Ignition Coils--New Evap Canister-- Shut-off Valve--New Timing Belt and tensioner-- New Plugs --New Fuel Filter-- New Battery--O2 Sensors both Front and Post Cat--Coolant Temp Sensor--New ETM Intake Pipe—Turbo control Valve

Get plug at #1 metered to see if you are getting any electrical current. Its possible you may have a short somewhere, usually it is at the plug as it gets really hot underneath those plastic covers, wires sometimes lose their insulation and get brittle.

Next swap the Ignition Coil from Cylinder #1 to #2. If the problem has moved to cylinder #2, then it is the coil.
If the problem is still there, try swapping the plugs next. I know you have changed it, but best to make sure.

Here is a step by step guide.

Pretty easy.

Notice how the looming has all come apart under the heat of the engine?
