Hi everybody, new user here.

I was driving my 99 Saleen S281 when I noticed a smoke cloud behind my car. I was in the middle of nowhere with no phone service so I had no choice but to keep driving the next 100 miles back to civilization. The engine ran just fine until about half-way there when it started to run a little rough, then about 20 miles later the CEL came on, probably because the O2 sensors were fouled. I haven't checked for codes yet. I kept a close eye on the temperature guage...
