Hello together, maybe someone can give me a tip where I have to look for the error. Car: V70 II 2.4L 170hp BJ 2001 205TKM Prins LPG system Everything works, according to Volvo (Vida) no errors (except the interior air quality sensor). Sporadic – I can’t detect a scheme, during the cruise the cruiser gets out (sufficient, if only CRUISE in the display and it does not regulate), same while driving, exactly at the point where it starts again admit gas – so from thrust mode changes (L Then he starts stuttering/rumbling, only with the gas acceptance, partly violent. If I drive so that I either give gas or not, everything is good (so do not get into the normal process). I stop at present errors and give gas in the stand, he stutters also here. If I turn off the ignition briefly during the drive, again, the error is short away, sometimes longer away – e.g. on the AB. Further: MM-DK was repaired at ECU, then learned at Volvo. LMM acidified rt and already tested with a DENSO – error remains… Lambda probe New (original Volvo), after which the static gas fluctuations were gone. Spark plugs New Ignition coils all new (no maintenance jam) All plugs cleaned, no visible cable damage. Speed sometimes goes into the basement (oil pressure indicator comes) however quickly catches. What could I try – without driving directly to Volvo (they are not keen on such orders, because the costs mostly do not calculate the time value t and therefore annoy the customer 😉 Otherwise he runs well, always starts perfectly. First of all thank you!
