changed spark plugs, tranny fluid, brake fluid, pcv valve. plugs are getting spark, distributor is turning which means timing belt is ok. was in traffic waiting to turn onto highway, when there was a brake in traffic, engine died, would turn over, but not catching. any ideas?

 

Theres a good chance that you coil in you distributor went out. I had the same thing happen to me, But if you have a spark then I do not know for sure. The tune up could have distroyed the old worn out coil.
