Hello,

I´m new here at the forum.

I have searched here for several times but was unable to find a complete answer.

I own a 4x4 Sapph which i love and a Escort Cosworth which i also love.

The escort is a car that was restored some years ago but hasn´t really been used, And when i bought i knew that it could still have some little things to be taken care of.

The thing is that the car is not boosting correctly and is cutting/misfiring, on boost.

The gauge states something like 0.6 bar of boost. It does not make any more.
This misfiring does not happen on the same situations. I can do a 70km/h-150km/h in 5 gear and it does not misfire, and sometimes in second gear it does.

Other times the inverse situation also can happen.

I´ve been said that it could be gasoline pressure, could it be?

It is really starting to annoy me because i have a Escort Cosworth that actually is slower than a Punto Multijet!

Thank you!
