Glad to hear that solved your issue!!! 
Not always the opti
Not always the opti Since I've had my car it had what appeared to be a ignition problem. When the car was warm it would jerk under a light engine load, say between 1000-2000 rpms and then would cease once rpms went up into 2500 up. Also while sitting at the light the car would idle up and surge forward like my foot was on the gas even though it wasn't.(A4) Read the book and did all kinds of tests, and finaly narrowed it down to either the optis or ignition module based on the symptons I had and what the book said, and also what I heard from other boards. Changed the optis including the cap and rotor which was kind a pricey(and plugged off the vent hole with RTV) and still had the same problem. Then I replaced the ignition module and still had the same problem.
Did some more research and stumbled upon the EGR valve and solenoid in the back of the emmisions section in the Chilton manual. The little light bulb went off, and luckily I had a friend who worked at O Reilys who let me bring back the ignition module and exchange it for a EGR valve and solenoid. Changed it out and the car runs perfect now. What made it so painful and expensive was the fact that the ECM would not through out a trouble code, so I kinda had to guess, but hey it's fixed now!
Sorry about the long story but I just wanted to share a piece of technial info that might help someone else if the're experiencing similar problems.
Moral of the whole story its not always the Optis. Mine was functional after 112,000 miles and was still tickin.

my EGR had a busted diapram. never ran bad at all. got it fixed recently as a few more codes came up. AIR system and O2's.
AIR problem was 2 bad valves not allowing for the air pump to spin properly. the air probably killed off the O2 by causing the engine to run overly rich.

Damn it! Maybe the advice I took was all wrong. I made an EGR blockoff for the Tube and it didnt seal... I was told if I unplugged the EGRs vacuum it wouldnt have any more issues..however I seem to have the same problem as I did before!!DOH!
I think im going to hook it back up and block that hole off!

Verdad Gallardo The car was stumbling when it got warm.. at idle it would run good... ses light would kick off...but as soon as you started off partial throttle (and in closed loop) the light would kick on and it would stumble, etc.
I knew my block off didnt seal..so I was pulling unmetered air in thru the back of the intake. I just thought pulling the vac from the EGR valve would fix it for now. Guess not.
