I replaced the o2 sensor yesterday, code 1 went away, but code 20 stayed. reset the ecu and this morining I was code free. I'm getting code 1 and code 20 again, but only after I drive for about 15 min. Then I can reset the ECU and Im fine for another 15 min. Then it will start chugging...but only when im driving. I can rev to 7k no problem if im in neutral. I DONT GET IT!!!!!

i have a mac and a crx with a b16a.. both with no problems..

 

check all your grounds.... take the gnd cable and sand paper the contacts to the gnds, even the 2 plugs that are on the wall behind the right headlight
that was doing my code 20....

 

is this in the 90? or your new king prepped hatch?

 

The king prepped. I'll check the grounds, thanks for the tip...but that wouldnt explain why the o2 sensor fails every once and a while.

o.k. so i drove it home from work. Tach still gets jumpy. if i kept it under 4000rpm i did alright...but if i mashed the gas, or tried to accelerate higher than 4k it stuttered and fell on its face a couple times. dizzy? fuel filter/pump ?

-Jake

 

are there any aftermarket electronics on it? such as an AFC or ITC? my vote is to earth ground that mother with some 4 guage. ground it all, everything. ground! ahaha

 

try formatting your motor.

 

No aftermarket electronics. Im using a d16 dizzy, but I have a sohc zc...that shouldnt make a difference though.

-Jake

 

agreed. make sure you have a cd rom installed, and use the "single cam for dummies" instructional disc. lousy car problems.

 

Buahahaha....I had no idea what you guys were talking about for a second...I was like ..Formatting? wtf?

-Jake

 

LOL, sorry Jacob I just had to share with the fellow HT'ers.

 

Hey...I wouldnt have expected anything less

-Jake

 

lmao!

 

note for anyone:

anytime any accessory or anything else is the car is electronically freaking out its always always something grounding or not grounding, and usually its not grounding.

id run new grounds to fix the problems

derek

 

kick it a couple times....maybe it'll work

 

so you have a sohc zc in the new hatch? are there any wiring differences at all between that and an A6?

 

Bingo.....the thermostat ground was loose. I feel like kicking my own ****.

-Jake

 

well the gnds was making my clusters go all crazy, gave me 12V on the gnd side, fried me an alternator, wouldnt let my headlights, horn, or tailights work, and all other ****... and u tell me u cant explain how it hapen?? gnd ***** a lot of things!...
