Thanks for the input guys

I totally understand what you mean. I had a plan to replace one thing at a time and test consumption under same driving conditions and get the results as to whether that change helped

I have found a MAF from Ralf (thought I'd forgot to take it out when I scrapped Ralf) and it's the same oval fitting

so I'm going to stick that in as my first port of call to see if that makes any difference. If not I have a spare MAF

So that's item one so so far its not cost me owt.
Next thing is (I know you didn't recommend it but...) my mam took the car to a local MOT tester and parted with £5 to get the exhaust emissions results. Whether this makes a difference I don't know but it's something thats crossed off the list as the bloke said the emissions are perfect

here's the results.....
Fast Idle Test: RPM-2590 (Test between 2500 and 3000 RPM)
CO - 0.02% Vol (Max - 0.20)
HC - 9PPM (Max - 200ppm)
Lambda - 1.26 (Min - 0.970. Max - 1.030)
Natural Idle Test: RPM - 630 (Test between 450 and 1500 RPM)
CO - 0.01% Vol (Max - 0.30)
OVERALL EXHAUST EMISSIONS - PASSEngine tested on warm engine.
All things passed. What do we make of those figures. The guy said really good. Not sure what that Lambda test shows - can anyone tell me?
