Pull the codes. I'm thinking that someting is responding a little slow to changes the computer is making to the fuel mixture and causing the O2 sensor to momentarily sense a rich condition.

Good luck,

I took it over to my buddies shop and the o2 sensor the plug was kind of crappy don't think it has been replaced in a long time since I put a new one on it has run fine and no light thanks guys for you're help

I do have one question about my other bronco I have put a timing chain and heads,water pump distributor and street fierce controller what is the best timing setting to run it at ? or should I stay with the factory setting?

It has a 351 with shorty headers, new heads ported and polished,Ford racing gaskets though ought the motor no air system cold air intake and no tuning yet .

It is waiting for a alternator (had it in the back of my Eddie and someone need it more than I did apparently they busted out the back window to get it and some tools f him) thanks,Sam

If it is an EFI engine, I'd set it per the factory specification. the computer will just attempt to move it back to that any way. If it is a Carbed engine 12 to 13 BTDC works nice.

Good luck,
