Last time I ran my truck at the track I had about 15 gallons of 93 in the tank mixed with 4 gallons of VP C-16

Seems like ever since then my truck will randomly die, sometimes after I start it and sometimes just idling. Like every now and then (about 15% of the time) I'll start my truck and it will immediately fire up, RPMs will shoot up to 1000 for a split second then it's like somebody cut all the spark it dies immediately. Now if I'm quick I can pedal it and keep it alive. Or I can let it die and start it again and it will likely start and idle as normal.

Also it dies while already idling sometimes. I'll be in park idling for over 10 mins straight w/o any problems then all of a sudden the truck dies.

Like I said this seemed to start happening after I ran that leaded gas, but IDK if it's a tune problem or a O2 sensor problem...

What do you guys think??? I've been trying to call Wheatley for the past few days because I need a tune anyways, but I was j/w if I should invest money into sensors before I drive to Houston...

 

I've heard that if your running cats the leaded fuel could ruin/clog them up and that might lead to the prblem. i had a similar problem when i ran enough octane booster for about 30 gallons and some race fuel, but it only seemed to happen at fist after i put the race fuel in. don,t know why, i just figured the computer compensated or it.

 

02 and leaded fuel do not mix.... From what I hear

 

Yea, leaded fuel can kill 02 sensors.
