Boy, I love/hate the Volvo Bricks......

My baby "Chokes/Stumbles" off a dead stop (ONLY WHEN ENGINE FULLY WARMED) and bucks at cruising speed (40-55) when not accelerating heavily. I can blast through the hesitations by hard acceleration.

This is my 3rd Brick, and I thought it was an AMM problem, so I replaced it with a used AMM first. Didn't do a thing.

Since then, Ive done:

AAM
Fuel Filter
CAT
25 amp engine fuse
In-tank Fuel Pump
Fuel Pump
Fuel Sensor(the module above the passenger side leg space.)

Nothing's worked. Key is that it doesn't happen on a cold engine. I should note car has very high NOX reading, since I bought it a year ago

I'm ready to try Voodoo---AARRRGGHHH!
