Well, I've been having this problem for about 2 weeks now and I think it's finally here to stay. Occasionally, my car would die when idling, and stumble real bad when driving around sometimes. It was intermittent. I assumed it could be the egr (fixed that) fuel filter (replaced that) timing(adjusted that), MAF (it checked out fine)... Well, I went out to work on it some more this morning and it refused to start. I read my Haynes and it turns out you can check some of the codes without a code scanner. Just jumper the test lead and such and the check engine light flashes in binary to give you the three digit code. Turns out I have codes 211 and 212. Code 211 is the profile ignition Pick-up circuit fault and code 212 is the ignition module circuit failure/SPOUT circuit grounded. I checked for power to the ignition module and checked for a good ground. I have both. I checked the distributor. It looks like it's got some miles on it but all the pick-ups are good and their isn't any carbon build-up or cracking and such. I checked the coil to see if it had a ground and it didn't. Now for the 20 million dollar question. Do I need a new ignition module? If so should I get an aftermarket one or go for the stocker? I'm guessing aftermarket. Please recommend some brands. Also, on a side note. I installed a air/fuel mixture gauge to help troubleshooting to see if I was getting too much or not enough gas. As it turns out (yesterday my car was running) at WOT it's as lean as it can get and the instructions said the car should be running slightly rich. Everything else appeared normal with the gauge. Is this a related problem or a second one? No other codes were pulled from the memory so maybe the gauge is wrong? Please help. I can't stand to drive my wifes corolla anymore...
