right,ive had a compression test done (thanks to bob property off gticlub forum) and the results came back as 150 per cylinder which means the engine is fine
BUT I THINK IVE SOLVED THE PROBLEM!
yeterday,i pulled the manifold off and this morning decided to fit the new one i bought from scrapyard(same manifold from the engine that is in the car now),i took the fuel rail off the old manifold and it wouldnt fit on this new one,so i went back to the garage and looked at my 1st engine,i pulled the fuel rail off that and put that on and it worked.
what the garage guys had done was before this engine,i got given a knackered engine by another scrapyard who claimed it was 1.4 but was actually a 1.6aee,he had put that manifold and injectors on to this engine,the manifolds are totally different,theres no niple fo the fpr vacuum hose to go into,anyway,i put the right manifold and fuel rail on and took it for a 30mile round trip on the motorway,the fuel needle ever so slightly dropped (compared to 1 whole bar dropping after 15 miles!)
also the temperature goes to around 70 degrees when driving rather than dropping to zero and the hoses dont get airlocked anymore?
im going to drive it for a week and see if the mpg has improved
i changed the oil and filter as the old oil stank of fuel
THANKS GUY FOR HANGING IN THERE WITH ME AND HELPING UT,COULD NEVER HAVE DONE IT WITHOUT YOU!
SILLY ERROR BY THE GARAGE MECHANIC CAUSE OF ALL PROBLEMS!
