leaded gas?
i was wondering will my car run with leaded gas, i am running fuel injection, but i dont know if that would effect that. i do have a gutted cat, but i am running all the other emissions except the egr valve. reason i am considering leaded gas is to prevent some detnation in the higher rpms past 4k, i have ran 104 unleaded gas and works ok. this is not for every day, just occasionally when i go to the track.

Re: leaded gas?
Not that I know of. (special O2 sensors). Leaded gas will burn up your O2 sensor.
Where are you finding leaded gas anyway ? Usually at the track they will sell 104 unleaded, (like you said) so you may as well run that when at the track, then just use your basic 94 to drive around town eh?

Re: leaded gas?
here in fl we have sonoco stations that sell 100 unleaded on the pump at most stations which is cool. But if you cant run unleaded your best bet is to run a late model aftermarket o2 sensor with a heater. I Run a 94 pick up o2 on mine and wired it to a relay to make the heater work. It will keep it alive longer as the heater can burn off some of the lead. The car will run better and allow you to make it go into closed loop faster. Runs better cold with it so really should do it anyway but will work better with lead. I know a buddy had a supra and got special o2s that were made for lead but high$$$$.

Re: leaded gas?
first thing is to change over to a heated o2 to at least help with it. If you bounce back in forth it will live a while. I have been doing it for years with stock gm heated o2s.
