mpi no power+ over fuelling
Turbo Mini Forums

my 2000 mpi has no power, seems ok until it gets to 3000rpm and over. it also over fuels after 3000rpm too. any ideas? i have replaced the lambda sensor but no better.

tps, map sensor, vacuum lines, air temp sensor, coolant temp sensor, cam phase sensor.

I'd start by checking the wiring to the sensors.

Cam sensor can cause lack of power and over fueling, basicaly the ECU goes into limp home mode and non sequential.

Best thing to do is get it to a decent auto diagnostics center and have a diagnostics done on it. When I say diagnostics center, i mean somewhere that specialises in engine management systems, not Minisport, Minispeed or P&L Minis.

Try this like to help you find one http://www.atpelectronics.co.uk/

Do not continue to drive it, Get it fixed quick or you will melt the cat, seriously!

thanx alot i will check the sensors out and get it on to a diagnostic scanner. how do you get it out of limp mode once you have sorted it or does it do it automatically?

Hi,
It'll should sort itself, but it's always best to get the faults cleared from the ECU.
Then if you get another problem it's obvious what it is.
Cheers,

check for leaky hoses?

it was a fault cam sensor, it never had a fault code on it though had to go through it checking it all and found there was no signal from the cam sensor cheers for all your help!

Glad you got it fixed
