Sorry to have been so curt, but I needed an answer quick to get my son running for the weekend. He ended up just getting rides from others. No big deal.

So, to continue the saga...

The car started running without "the intermittent problem", so much so, that he drove it to school the following week (yesterday). But then another problem developed where it would fire up and die immediately. Not knowing and following the suggestion of a friend, I took the CIS box out of my race car and put it into his car (side of the road in the rain), but the same problem. Again, this was a different problem (not really) because the car wouldn't even run on one cylinder. So before putting it on the trailer, I checked the mass-flow sensor and guess what? The pop off valve had completely popped out! We stuck it back into place and the car fired right up. So he has my CIS box and I have his CIS box and the car is running fine.

Final thoughts: I suspect there was a hairline crack in the epoxy around the pop off valve that would intermittently cause the car to act up. So anyone who said vacuum leak was correct.

I should have just stayed home last weekend because I crashed my MG Midget race car on the second lap of the first race and was done for the weekend.
