Hi everybody from Spain

I recently collected my 93 Mx6 from mechanic for valves, manifold and TB gaskets, new PCV, fuel filter
and replace all bad vacuum lines.

But it jerked and idle was low and really erratic. Took it back to mechanic and
checked compression (front side around 125-140psi, but rear all 75psi).
After moving replacing spark plugs he managed to make it work fine.
But after 1-2 minutes of drive, it has began failing again.

Must say belts have been replaced and my distributor failed, so we replaced a month ago with a used one.
Before replacing gaskets, etc.. I noticed it shaked a bit at around 110-120Km/h, but I though it may be because
the water pump installed for now is 16mm on a 32mm water pump (soon to replace).

Could the disty be faulty? or should I check other things? My wires (have 2 full sets) are quite new, also spark plugs..

I had an issue where I had oil seeping through the distributor causing spark to go funky especially at lower /idle speeds. You might take the distributor cap off and see if there's any oil residue inside.

At this moment mechanic heard a hiss from injectors and idle reacted when spraying so he thinks there may be an air leak from bad o-rings seals ...
