When I had my 996 I got really good help from Richard
But now ive downgraded to a 98.1 I don't seem to get the help
Ive had slight misfiring or heasitaion at 1500- 2000 revs not accelerating
bought an Autel AO200 which gives some impressive readouts
One gives separate Engine Roughness on each cylinder and they are very different
Have you any idea what it means or where I can get the necessary info
Following are Readouts
Engine Roughness reference Value 5.9014
Cylinder 1 -1.081
Cylinder 6 1.140
Cylinder 2 1.041
Cylinder 4 -2.028
Cylinder 3 1.456
Cylinder 5 0.336

The 6 Missfire reports sow as 0
Have enclosed a PDF in case it helps
Must be the same on 996

Thanks

Does the software explain those readings? Misfire could be caused by coil packs - check for visible damage or cracks to resin seal. You could try swapping coil packs to see if misfire follows. If it's a bank, then I would suspect a faulty solenoid on the vario unit. You could also have problems with fuelling. You really need error codes to narrow down fault specific to Porsche.
