i'll explain this briefly...piston number 1 at tdc,,, the cas unit on side of head... take that out and u will see a little slot cut on it and there will be 2 dots in front of it the right dot and the groove should be in line before u push it in...and then wen u push it in the cog engages with the cam and the second dot lines up with slot which is the one on the left and then your timing should be perfect...that is if the rest is right.. there is a dot on both cam shafts and 2 black links on timing chain they should line up also there is a gold link on chain this should line up with dot on crankshaft
then reload the tensioner

crank pully should also line up with the first mark on the pully and then it should idle at 850rpm

any info call or text me on 087 170 8812

do a compression test and see is it holding... u could hav a bent valve..i had a sr that bent 2 valve's and broke chain and broke 2 rocker stoppers and it was only thickin over...i was sickened coz same mornin it was the friday of rally of the lakes and i had car loaded and everything but back to u i'd check that and then i suppose check coilpacks and spark plugs while your at it..i persume u checked air flow meter... also just reading over this i had a r32 wit similar problem and it turned out to be the fuel pump u might not think so but worth a try
also throw up a list of wat ya changed so we know wat ya hav done

i changed... lamda sensor air flow and sparkplugs.. the compressin is good on all cylinders.. i dont thing its a coil pack myself its runs too good between 1500 rpm and 5k... its just like a miss there and when it goes thru that its grand again to the limiter... i did notice the plugs are very sooty.. i did try the amplifer on the old engine to cure the idle prob but it didnt miss at 5k. there is a neo in it wired wrong.. im going to pull it out to see if this is the prob with the idle.. any other ideas or hints or tips will help

thanks
