Dear Scotty,
You're my last hope for survival here.
I have a 2000 Toyota Sienna 3.0L V-6(california smog) with 260k+and every two or three weeks I get an engine check light throwing the code 1150 and less occasionally with an 1130. I already know that they are the a/f ratio sensors on both banks but before I go and plunk $300-$600 down on new a/f ratio sensors.
What I want to know is if a small amount of coolent, say maybe a pint to a quart every 2-300 miles(no oil in water, no water in oil, no leaks on ground so this is assuming a blown head gasket), being introduced to the a/f mixture could be causing the code? And if it could be, what gasket repair stuff would you recommend?
I should mention I checked the heater fuse and it is good so no blown fuse.
I wish you lived close by. I'd love you to scan this thing. Everybody around here wants hundred dollars just to diagnose the problem.
Thank you in advance for any help you can offer me.
Love your show and am a subscriber on youtube although I wish you'd go to Rumble.
Sincerely,
Steven Bradford
assuming a blown head gasket
have you changed your pressure cap?
no leaks on ground
sometimes it simply evaporates before hitting the ground. Or maybe it only leaks while driving.

No but I will check the cap. My big concern is getting this thing to pass smog. I've got to stop it from throwing the codes which have now become Permenant Displayed(P1150pd&P1130pd)which means I'll never reset the monitors now.
