Default HELP engine won't rev above 3000rpm
Hi I just bought a donor car for my mk4 escort combi, it's a mk1 mondeo 2.0 Zetec (silver top) n it won't rev over 3k some1 said it could be the mass airflow meter and that if I unplugged it and it revd all the way with it unplugged then it's that what's gone so I unplugged it but it still didn't rev over 3k. So if any1 could help it would be much appreciated. cheers stu

Throttle position sensor. Id go there next if you've ruled out the air flow meter!

Yeah also the cat could be blocked! Take it off and see if it'll rev then. Be noisy mind you but worth a try!
