RG TM8 A/F gauge ????

[Klimbing Kitty]

So soon as I give it any throttle my A/F gauge hits 17 and then -- out. Added a bunch of fuel and it does the same thing. I have fuel pressure. Where do I start to look? Thought it might be a bad probe so I changed that and it made no difference. It was working fine yesterday. Any help would be greatly appreciated

check for cracked ypipe...pipe..any exhaust leak upstream from guage

Is it over-boosting? When ours went wacky, it was a cracked tube to the control box (Pure Logic).

Could not find any cracks but the Y pipe donut is just woven rusty metal none of the silver coated stuff is left on it. hoping it is just the problem. Will c tomorrow thanx guys

a/f gauge

dont know if you got the my message but your gauge had alot of moisture in and may just need to dry out. try drying the connection at the gauge and if not use the one off the 1200 for now. see you wednesday.
