g16's dont shake cold or hot, they do not.
unless it's misfiring and that is not normal at all.
it for sure is NOT THE IAC doing that, faster idles actually burns better ! extra air , better.
if compression good.
lash good.
egr not stuck open (its new and not)
spark timed, at spec, (freeze jump set)
plugs at .7mm spec, not at NGK factory setting, ever.
MAG wires, are a huge value here, hot spark always is on all Otto cycles engines.,
if that is good, then it has fueling issues , purely, not air issues.
i tend to think (magic crystal ball) that its leaking injectors. but no proof yet, just that black cloud over the car.
if on a hot engine rap the MAF with back side of screw driver, if rpm changes, maf has serious problems.
gently.
here is my live driving map plots 1 of 3 on my maf page
this is real. from my 96 scanner, and dumped in to MS Excel.

in the end we do fuel pressure test over 10 of them.
the ECU on this car does not monitor pressure nor correct for it.
it just injects wrong when pressure is wrong. (o2 tries to cure it sure but 02 is dead, accelerating)
we are working 2 separate issues,
misfire
and bad idle cold. (races, not stalling)
so seems confusing , but is not.
misfire usually causes stalls.
if present,, and never racing, ever.
