Poor compresion in number 4 or leaking inlet gasket maybe, i once had a problem with number 4 and it was the sral on the brake servo pipe to the inlet the seal had a split in it and was make the car run on 3

[stevie78]

whats the sral?

[steve.hicks]

Think it was supposed to be seal!!

[stevie78]

is that the join inthe middell of the vacum hose going from servo too inlet?

[Riggy]

check lead and dizzy cap first as they dont cost anythin

then come back
