As per title purchased a 2001 2.6 v6 cdx on friday with 70k. Mot backup miles but error on after shortly after leaving for home.

As its effecting both banks any ideas on what to check or if it looks like worth returning car. Oh and intermittently has rev climb to 2k at idle when stopping for lights etc

Has the usual rocker cover leak although slight

When clearing the codes car ran rough for a short period of time

Will get carb / injector cleaner to check for leaks but nothing visable
Thanks

If you have the ability to read live data, what is the MAF reading at idle?

Additionally, look for air leaks in the intake and vacs.

Fuel trim malfunction on both banks. Its a 2.6.

Swap the maf for a known good and try it. (Same maf as 3.2 and various other models)

Do check for air leaks though.

Thanks for the pointers guy's

Seemed I had other issues and after replacing faulty battery, rebuilt alternator, replace spilt o ring in plastic bits on intake, refitted hidded vac pipe which had come out.

Replaced afm with one I had spare from original 70mm amm. Well sensor the same and giod as gold now

Do have rocker cover oil slight leaks and other minor bits of interior trim to sort it is good as gold

Needs lsd but even likes a little drift lol

Tempted with v8 conversation but not allowed after s3 tfsi conversation in my vx220 turbo and race car
