I am bit confused. I was testing my egr valve, using vacuum to stall the car. The car stalled like it should. However it would refused to start. I had no spark at all. It tuned out to be the TFI. I put in an extra distributor I had and it started right up. I don't get it.
Something similar happened to me when I was working on a friends car. He drove it to my house, I ran codes, found out the water temp and throttle position sensors were bad. So I changed them and then the car wouldn't start. After some testing, I narrowed it down to the ignition switch. Ran to my parts pile and found a spare, installed it and the car fired right up. His old one was melted really bad. The whole time I was testing it, my "friend" was accusing me of doing something wrong while I was changing the sensors and THAT was the reason it wouldn't start. When I found out it was just a coincidence that his ignition switch decided to take a dump at that very moment, he felt like an idiot... but didn't apologize though. Haven't helped him with his car ever since.
TFIs have a tendency to go on Fox cars. You're lucky that yours went where it did. The EGR and stalling didn't cause the TFI to fail. Nor, did the EGR and stalling cause the winning lottery ticket last night.
I have been waiting a long time for that thing to kick the bucket. It is the original module and has 186,000 on it. I'm just happy I had another one. Damn weird though.
