2.2 Mis-Fire

[spennny]

I know your all gonna say fuel pump, but its not long been replaced so what do you think, and it was the continental one

So this is the 2nd time its happened in the last week, i cleared all codes on Sunday , and got some fresh codes

It says below that my fule is running rich, and the earlier fault was

P1191 - Fuel Pressure System Malfunction

I then managed to get the below info, do you think its the regulator or pump ??

Would that make it run rich mate ?

How do I clean the MAF , shoot some cleaner or something up there

Hmm interesting mate my mate has a 2.2 aswell with a k&n re oiled it it misfired when he speed up and was slowing down I checked everything then he told me he reoiled filter so I put my pipercross in his and it was fine he now had piper and it's spot on maybe coincidence but his is fine now

I haven't re oiled mine for a while mate , the 1st time it happens was last week , and then again today , and the spanner light stayed on whilst driving, when checked it came up with what i posted above , I have cleared it now so will see when it happens again , will call my warranty company into action :-)
