Hey, last couple have days my engine has been hit or miss if it starts up. It cranks up every time but sometimes struggles to start. 
 

Ran the fault code P0172 and notice I had high negative SHRTFT1 and LONGFT1 % of  around -20% to -30%. 
 

I only have that one error and it’s seems to be completely random. 
 

any help is appreciated

P0172 is fuel too rich. Try a new airfilter but it could be MAF? Might be worth disconnecting MAF,cleaning contacts and reconnecting.
