It was misfiring above 4k rpm, also had code 34. I rewired the connector and reset the ecu, no more code 34, all clear. Changed the maf and the misfiring stopped on low boost but still there on high boost. Also got code 34 again!

 

When it misfires i cant hear any rattling, its just total power loss.

 

Im going to change the plugs next but its really starting to pi** me off!

 

What percentage should my a/f be at idle and full throttle?

 

Is my car detting?

mine is fixed! Was a boost leak

 

Now got code 53 and need a new prop shaft tho!
