Missfire @ 4.5/5k
Hi got a stg 3 saph and ive got an intermet misfire at 4.5/5k'ish. Seems to do it in 1st and 2nd gear only just holds back like the powers been cut-off. Rev counter doesnt go off the scale much but does jump up and down
Changed rotor-arm
checked phase sensor, spark plugs (havent gapped or changed them as there Denso Ik27's and Karl @ NMS said they wont need gapping or replacing anytime soon)
running Group A coil
cleaned-out multi-plugs on the bulkhead
etc etc
Funny thing is i had it live-mapped @ NMS back in November and eversince now the car was bang on untill I took it to a rolling road meet with PF group back in Feb i think it was. It drove up fine but eversince Nobles put it on their rollers it miss-fired and from then its been doing this.
Question is could it have anything to do with it going onto the rollers or what to they take off/adjust on the car when it goes on the rolling road as this could've upset something or maybe they forgot to put something back on?
Anyother suggestions as i dont really have the funds to get it checked over by someone and want to have it ready for the 1/4mile at Central Day?
Cheers

with my car the first time the problem happened I had the loom plugs removed and joined the loom together, this lasted for about 16 months but then problem returned, now have new engine loom and all is sweet

I had the same fault with my 4x4 saph when i first bought it.
Tried everything. Cap, rotor arm, plugs, leads, coil, crank sensor, phase sensor, tried the multiplugs on the bulkhead the lot.
Eventually it was traced to a dodgy ignition amplifier. that was replaced and was sweet as a nut after.

Similar to above mine started playing u after a RR setup (fine on the rollers).
I changed loads of stuff, ig amp, dizzy cap and arm, crank sensor, temp sensors, leads, plugs.
Some items improved it slightly but never fully fixed, so i bit the bullet and bought a new engine loom, and all is OK now. The wires become brittle and break down, these are now old cars remember.
