W211 1,8 compressor, hasitation up hill
Can't figure out the error and have thrown some parts at the problem but can't figure out the problem. Hope someone can help me in the right direction. When the engine is hot and the engine gets some resistance, uphill, the car starts to shake, hesitate, just as if it is the wrong ignition or something. Have checked the machine and find no discrepancy between tachometer and movement on the converter. Has replaced Maf, spark plugs, 02 sensor front and a Vacuum hose that started to show signs of wear. Tested for vacuum leaks, smoked the engine to check false air etc. used torque to see if I got any abnormal readings get up just before the engine jumps, holds back, hesitates incorrectly in 02 sensor 1 but stabilizes and runs normally again without error message. What could be wrong?
