If im posting this in the wrong place my apologies its my first post just getting used to the site 
I have a problem with my 2001 (y) omega 2.6 (y26se) it was running like a pig for about a month i parted with a £100 to my mechanic who first told me to burn it (cheeky sod) then spent four hours cleaning breathers and checking codes on ECU, he almost got it to run ok not great but as soon as i got 50 yards from the garage it started again (as soon as it was under load) - revving to 2000 revs then dropping waits a second then repeats also missing badly when cold i solved this two weeks ago and quite honestly its driven like a new car (i unplugged maff its been unplugged for two weeks now). as i drove to a set of traffic lights last night i get a loud whining sound from gearbox as i stopped car it stalled i tried to restart with no luck the only way i can start it is to hold accelerator to floor i have to continue to floor accelerator soon as i let pedal off it stalls it revs at 200 maximum yes 200 folks! and it wont rev any further, exhaust bangs and rattles and whole car shakes whole engine knocking badly also noticed a quarter of and inch of mayo on oil filler cap and oil filler pipe (no oil in water or on dipstick) did not overheat before it died temp was at 83 first problem i knew of was the whining from gearbox it ran like a dream up untill that moment i dont know where to start looking  and would appreciate any help at all please excuse my typing im half asleep lol thanks in advance

Im most likely wrong but a few years back I had the same or similar problem to the hi lighted part and it was the Air Flow Mass Meter.

I'm sure someone with more experiance will come along soon enough

And welcome to OOF

Thanks for the welcome omegaman thank you for the fast reply i unplugged maf about two weeks ago following revving issues it ran fantastic with it unplugged my fear is have i potentially broken something by leaving maf unplugged all this time which has now led to these new issues  i have literally never heard a car struggle like this to keep going like it is now, 1960s tractor springs to mind when you hear it lol

That could have caused the problem, I got a replacement from eBay from a well known used parts seller Omega Spare Parts £25 I think it was for a genuine Bosch (used but working) and after fitting that 3-4 years ago its still fine. Hope you sort it mate

Have a look in the maintenance guides for the pedal trick and then do it Then post the codes you read on this thread

Welcome to the forum and don't worry, it's highly unlikely that unplugging the MAF has caused any problems

Oh, and the mayo is common if you mainly do short journeys and nothing too major to worry about.
