So got the engine in the car going but its running shite

misfiring shaking left and right on idle - calms down a bit higher up the rev range but still not running right....

anyway after spending a feckin age looking for vacuum leaks - I've narrowed it down to cylinder two not doing anything...

basically I can unplug coil two and it runs (nearly) the exact same...


what I've tried so far...

there is no vacuum leaks
changed coil pack harness
changed coils
changed plugs
earthed coil harness to battery
checked and getting spark on all 4 coils
getting fuel to rail
getting fuel in injector
changed 2nd injector anyway
all four click
tried different ecu
tried different cam sensor
played with ignition timing (kinda makes it better or worse but nowhere near where it should be)
I did the timing belt before the engine went in - took cover off and factory marks still line up
Did diagnostics using the led on back of ECU - 5 red / 5 green "no fault code found" on both ECUs - cunt

at one stage while it was running I unplugged nearly every sensor one by one and all it does is a little fart and keeps running the same way - won't start with maf unplugged... this has a lambda sensor old engine didnt - tried both ECUs with and without lambda plugged in - no difference........

its got a t28 and walbro now but fairly certain that has nothing to do with it


its got 110psi compression in cylinder 2 - which is low and I know its low but from what I've read online there's people rocking around with CAs for years with around 100 across all four.
Cylinder 3 has the same compression, if I unplug the coil it dies so that's why I'm thinking its not compression. The engine isn't great I know its got 140/110/110/130 cylinders 1-4 but I still think its strong enough that I can drive it till I get the cash monies together for a fresh one...


anyway.... any ideas ?


put an SR into it they said....................
