Well thanks for that chaps now my mind is really blown what I’ve done is taken readings on the nanocom now I’ve replaced the old air filter and cleaned the maf so will take reading’s again this evening and look for any changes then I’ve found...

U lost me mark short term fuel trims what does that mean in none mechanic language cheers

Here’s a few pics I took of readings before & after a 40miles drive I’ve got live data aswell will try to up load it later can anyone spot a major change or problems just from the pics

Also just ordered some more maf cleaner give that a clean aswell just had a look on rimmers site for original oxy sensors 2nd mortgage
