Default s2 misfirin under load

ok, heres where the story starts.....

after replacing my headgasket about 100 miles ago, all has been running fine, oil and water levels r fine, temps have been fine, evrythin has been spot on. then this mornin i go for a drive, change dwn frm 3rd to 2nd, not violently, just as normal, because im stil driving it gently to settle head down. all of a sudden it starts to misfire.

i pull over and check it agen. on the spot it seemed fine, so i figured it had justr been a freak prob, then soon as i put it under load agen wen i lifted the clutch, the mis cama back.

heres where it gets strange. wen im in reverse theres no misfire, or wen its stationary, its only in forward gears. so off i go for a compression test. results r fine, all same reading all the way across. so not a head problem clearly. piston rings r fine and always have been, no smoke frm exhuast under load, so they must b fine.

so, hmmmmm, any1 got any ideas on wot this cud b??? i kno iv got a dodgy top engine mount if thats going to affect anything maybe?? any ideas would b greatly appreciated. im due to start a new job monday so having the car fixed by then wud b ideal

I had a miss fire the other week turned out my coil was loose

Check your leads arent brakin down due to age or heat and check plugs, dizzy cap and rotor arm!!!!

all checked, all less than 2 wks old aswel, so thats a no go

how does a split fuel injector hose sound to ppl??? iv got a split in 1 of mine, im assumin it wasnt openin up until it was under load, its now completely split and sprayin evrywhere, so its a permanent misfire. im takin an educated guess that the lack of fuel to that injector means no combustion??? must do really.
