EZ EFI Problem

Installed it last weekend had it running for about an hour and an O2 error code that will not clear. Pulled the sensor and it was carboned up so tried to clean it up to no avail still set a code. Checked it and it is heating up but code is still set.

In checking my lousy welding job on the bung to hold the O2 sensor I think there may be a little leak in a spot or two would this contribute to my problem?

Re: EZ EFI Problem

I wired it exactly as layed out in their instructions.

The O2 code did not set until it flooded out on a start-up that I did not have time to let the motor fully warm up and it ran rich. I read something somewhere to that said make sure there is no leaks around the sensor as it could also throw it off. I am going to re-weld a few spots tomorrow to see if it helps.

Excessive rich can ruin a sensor quickly.

Re: EZ EFI Problem

mine was rich to so rich it was dripping out of the mufflers, i pin hole or two isn't going to matter much. I wish i could find my emails i had with fast…but i had the issue when i installed mine last year and for me it was a power and ground issue. Then the code would clear and the car ran perfect.

It was soooooo rich, you could see the gas the gauge move..lol In the end the o2 was fine and its still in there.

Re: EZ EFI Problem

Kelly, any luck in finding any of the FAST emails? I changed the O2 sensor code still there. They asked me to check some voltages which I did and reported them back just waiting to hear back from them.

No…darn it, i searched all my emails and its gone. They were very fast in replying. I assume your fuel pressure is right?…does the coolant temp sensor read ok?…

does the engine have a big cam?…are your iac counts correct?..

Re: EZ EFI Problem

I have not been to impressed with their product support. One person I talked to there knew less about the system then me. Been trying to make contact with someone that can help me solve this.

Re: EZ EFI Problem

I finally went onto their live chat line and connected with someone, Gabe, who actually steered me in the direction of checking the height of the pins on the ECU connection as he said they have a tendency of sinking. Leveled them all plugged it back in and problem solved. Now I can get to driving my car!

So was that it, poor terminal connections?

Yep. A little hint for anybody doing an install. Rough fit the ECU, pull it off and plug in the connection then put it in its final position. You should avoid the issues I had.

And another note the timed vacuum port is greatly effected by the butter fly position. In doing the setup again I opened up the butter flys and now the vaccum advance on my distributor is not liking it much. I may just disconnect it and see how it runs from there.
