work this one out (clevo problem) missing when hot
Ok to start out will explain what i have
2v closed chambers
wieand single plain intake
vortech V2 supercharger, hitting 8psi of boost @ 4500rpm.
ignition system is laptop programmable megaspark, (based on Megasquirt (do a google search) )
and has not given me any trouble at all since install a few months back.
in last week have put on new leads, colder range plugs with .5 gap, new cap, and rotor... have tried a different coil as well, my coil is mounted on the shock tower so it shouldnt be getting overly hot
now to the problem
about 2 weeks back it started missing and stumbling on off idle acceleration, then once the revs get up it goes pretty well,
progressively got worse, now to the point that you cannot nail it from stand still, it just dont go anywhere and feels as though someone yanked 4 leads off, but if you gradually accelerate with the missing then nail it around 2500-3000rpm it gets up and goes
this only happens after the motor warms up, will run perfect for the first 1 - 2km of first thing in the morning driving. you can bury the foot to the floor though first and 2nd up to 4500rpm from stand still and it will pull clean the whole way...
after that at say the traffic lights at idle it misses on at least 1 cylinder. and takes off like a dog.
now today i did a compression test, did a cold one, didnt feel like burning hands playing with it today, i know i now have to do a hot test
the cold readings i got were
AND another thing was the other day on the way to work i had the bonnet up about half way to work to adjust LPG mix a bit and noticed that there was blowby coming out the oil cap like a chimney, i have been checking it every day since then but its not as bad, but you can notice it without taking the cap off
think thats about all
if there is any more info needed, let me know
