Sea Foam

After reading so many good things about Sea Foam I decided to buy some. I used it in my 1997 LeSabre and also my 1991 Toyota Camry.
The LeSabre now has the check engine light on (which sucks because I was doing this to clean the engine before taking it to be smogged. The light came on as soon as I restarted it), and the Camry refuses to start up again after letting the product sit in it for 5 minutes. Can anyone give me some advice on these problems?

edit: The Camry is O.K. now . I just had a little moisture in the distributor cap from rinsing the engine.

I put Seafoam in my 97 when I first got it. When I started it up, it idled really rough for 5-10 minutes. I cannot recall if my check engine light came on, but after a while it smoothed out and ran good. Maybe let it run for a while?

I've put about 100 mi. on it so far. I'll be taking it in to see what code shows up this weekend.

I'd say it's probably a mis-fire code.. I use seafoam every 6 months or so. I put 1/3 in the oil, 1/3 in the fuel tank, and 1/3 gets sucked in the intake.. Good stuff as long as you don't use it too much...or so I've heard.

Just thought I'd follow up. The check engine light turned off last night coming home from work. I had put about 150 miles on the car.
Now that I've done the seafoam treatment and removed and cleaned my egr valve I'm going to take it back for a re-smog. Any last ideas for lowering my N0 emmissions would be appreciated.

Thanks

NOx emmisions are kept under control by the EGR system. High NOx levels indicate high combustion chamber temperatures.
