Fuel issues?

[D-ROK]

OK, so I will try to explain as best as possible. Pretty much at idle afr's are holding at 11.2 When I try to give it gas I spike lean and car cuts out. Any ideas?


I did replace the t-stat today, so I dont know if it a coincedence, but I dont think thats the problem.

oh and fp is where it is suppost to be at idle. but i dont know what its doing when I am giving it gas cause I dont have a ic fp gauge. Im guessing watching the fp will tell me whats wrong.

Bump.

so I checked while parked and the fp stays the same, but it spikes lean when I give it gas.

Your afrs are in the 11s at idle!?!?!? What's your fuel setup look like? That's like cylinder washing rich for and idle afr. How high do your afrs spike when the car cuts out?

It goes lean off the charts. I have been running leaded race gas lately and after a little research Im thinking it could be the upstream o2 sensor? Or maybe MAP sensor.
Dunno tho, it started doing it all of a sudden and it didnt get gradually worse.

I have the BNF, FRL, Perrin Rail and DW 750's

Prob fixed! Dirty upstream o2 sensor.

I guess three tanks of 110 is enough to jack up the sensors.
