cylinder 1 command

[benn j]

Hi guys bin having problems with my 1.2 16v mk2 ph2 its bin missfireing on cylinder 1 intermittently then the other week it started to missfire constantly.
Its had a bit of a diagnostic session (been plugged in basically) and its come up with cylinder 1 command fault , low inlet pressure and i think it said after ignition relay faulty aswell
Anybody got any ideas what it could be? I know the command could be anything from the ecu if in correct?
Any help and advice would be great
Need this sorting lol
Thanks benn

What code reader did you use to obtain these as i've heard of a few "Cheaper" units throw "Low Pressure" descriptions before with no actual codes and as the D4F has no way of measuring cylinder pressures I can only assume its a translation issue.

"Cylinder 1 Command fault" - Again, a possible translation "Issue" pertaining to missfire detection.
"After Ignition fault" - Proberbly a broken wire or faulty relay in the main engine fuse box area.

Firstly I used the snap on solus dont get these loads with this then I used the snap on solus pro and got these loads.
Im gettin a compression test done soon to check compression

Yeah deffo worth ruling out low compression for the time it takes but I think it'll be MAP related.
