Re: loss of power

Hi

On my workstation there is a dotted underline for buzz words like MPI - multi point injection - if you hover your cursor it tells you what the buzz word is, I think the MPI have a flat spot at 2000rpm when cold, donno my SPI is real slow off the mark, until you get it into 2nd gear >3000, even when warm, slugs are us.

Re: loss of power

MPI= Multi point injection

But your car is SPI (single point injection)

All cinqs are SPI. MPI doesnt have the flatspot either as that was ironed out, if you are suffering a flatspot on an MPI it isnt a flatspot its something totally dofferent that is the problem

i would go with diawiks suggestion to start with (a service)

If this has already been done recently get back to us

Re: loss of power

i heard there is a pipe that goes from somewhere to the ecu, something to do with the pressure and amount of fuel that gets used.

could it be that.

Re: loss of power

nope you dont, MPI didnt begin in the FIRE engines till Oct 2000

cinq production ended 2 years previously at the very least so no way you have MPI unless car has been modified

Re: loss of power

in that case a suggestion of your problem is a possible leak from pipes e.g the vaccum pipe, would get them checked out, other suggestions from others will be made
