Usually when you have this sort of intermittent no-spark condition, either the coil is intermittently failing or the electronic ignition control module (sometimes called the 'igniter', esp. on Hondas) is having a problem.

Is the problem worse when the car is hot? That's another indicator that the coil or module is bad.

Good luck.

GingerL - are you in the auto repair business? I used to turn wrenches on BMWs for a living.

BMW's, for a dealer or as an independant shop? Either way, that's usually a fairly cushy job that requires quite a bit of skll and knowledge. It's nice to see those kind of credentials on Answerbag.
I turned wrenches for a few shops many moons ago, worked for a salvadge yard tearing down cars and selling used parts. I spent 6 years in auto parts as a career doing outside sales while catching "overflow" work from my customers. I was ASE certified, but I let that expire. Now, I'm a stay at home mom, and sometimes work part time for one of the parts stores I used to work for. If it was made after 95 or so, I'm out of my element:)

I was a dealer mechanic for 4 years and it was any but cushy. The problem being that management/BMW expected us to diagnose rolling computer networks (did you know a bad radio can put the transmission into "limp home" mode?) while still beating flat rate. I got sick of fighting that battle every day.

Most AE102-112 corollas and sv10 - 21 camry's with 3s 5s + 4a engines igniters fail and missfire intermittently, especially under load, carrying out a resistance check rarely shows the problem, and they have no OBD connector to use a IT

try checking the distributor. i suspect the ignition coil but not very sure. i will try tune up first... concentrating on ignition system... like spark plug & plug wires.

It could be a problem with gunked up sparkplugs or something in the electrical system.
