Hi

My car been sat for a few months while I changed the charge cooler system to an Intercooler also swap some water pipes. Car was running fine before just trying to keep the intake temps down.

Start the car the other day start fine run up to temp bleed the water system etc.. all run fine.

Went for a little drive and with in a few minutes the car started missing thought a boost pipe might of come off are so air leak

Went back home and couldn't see any pipes of but as I was checking coil packs on cylinder 4 made no difference if I un plug it so swap coil with cylinder 3 and still stayed on cylinder 4 so swap spark plugs still the same, then I swap injectors still the same.

Check all connectors with a meter and there power to the coil and injector

Fuel pumps has good fuel pressure and it's pretty new brushes pump

So I did a compression test and they was fine.

Any ideas

It's a K20,ID1050CC Injectors(6momths old),Borg Warner turbo, Haltech 1500
