Hi everyone, could check serial as acr 4 doesnt go into it, even though its a 2001. Engine is difficult to start from cold, it idles unevenly and lacks power till it gets warmer. The scope show all signals as normal, but car hadnt been sitting outside wehen i got to it, I tried to leave it to get as cold as possible. MAF SENSOR IDLE AT 1.5V, snap acceleration in the workshop rose to 5 volts at spike. This seemed quite good, certainly matched others ive tested. Has anyone found MAF faults causing cold start porblems but being ok at normal temp? Has anyone found problems with the CTS on this mopdel, it started at 4.8v and seemed to decrease gradually with no obvious faults. I need to buy an AD200 to do these cars now!! Thanks in advance for any help. James
