I had the same problem in my Ford F150 4.2. The light came on because there was a temp. sensing delay. I just wrapped foil around it several times to keep the temp. up and my light stayed off.Originally Posted by patricke123

Hi - thanks everyone for your input and help!!!! I reset the check engine light, but did not drill out the non-foulers and the engine light came back on - after the engine light came on the idle of the car was effected and it was frequently stalling when the hho system was turned on, but runs fine when the hho system is off. So now I am going to drill out the non-foulers and re-install and re-set the computer again. Should this solve the problem???
What would cause the car to stall when the system is on and run fine when off? Does this have to do with the check engine light???
Also, what part of the O2 sensor do you wrap with aluminum foil? Has anyone else done this with success?
Thanks again for the help!!!

It may stall if it's too rich or lean. Let me know if drilling it out to 9/16" works. You would cover whatever part or the o2 ensor that is sticking out of the exauhst pipe minus the wires.
Thanks - I installed the drilled out non-foulers tonight. The check engine was gone on and off - sometimes it would be on and other it would be off. I hope the drilled out non-foulers will work. Does the computer need to re-adjust to the hho and the non-foulers. Could that be what was happening?

I can only speak from my experience since I am new to this, but this is how I did it.
It's my understanding that whenever you introduce something new to your vehicles computer it has to learn to adjust to what you have done. I have had all of the problems you've described and more. Try unhooking the pos. battery cable for roughly 30 minutes, reconnect it and start the vehicle letting it and your HHO cells warm up then drive around normally for a while letting the cars computer adjust itself to your system and adjustments. Trust me when I tell you I'm no rocket scientist but this has worked for me.
Seeing as how we've had the same problems your vehicle should run better w/the antifoulers drilled out.
The check engine light is staying off but the car is still having problems keeping an idle and stalling. Any suggestions? Does it just have to re-learn things?

the computer can take hundreds of miles to get used to the new settings. it depends on how often you drive it and how far. when I know that I need to reset the computer, I try to plan a 200-300mi trip, reset before I leave and it is pretty much good to go by the time I get back. if we are talking about a daily driver that sees stop and go traffic every morning and is mostly idle or low gears... the computer is not likely to "get comfortable" any time soon. try to use the method I mention...
another thing to keep in mind, the computer is looking for consistantcy. if your part of the world is cold in the morning and warm to hot in the afternoon, eviroment may play a part in computer adaptation as well... type to keep enviroment as consistant as possible while you are getting to the computer through it's learning process...
Are you using a MAF sensor enhancer?
No MAP/MAF enhancer - the Jeep is still having problems holding an idle and still has check engine light even after drilling out the non-foulers
Have you had your codes read? If not go to autozone, they will do it for free.
After I had mine read the first time it said temp. sensing delay, the next time they were read it was fuel mixture was too lean.
