Okay here is the situation. When driving for extended periods of time or over 100mph I get a engine code for the O2 sensor. Then the car starts running shitty and bogging with anything under 4000 Rpms. However when I turn the car off and on again the code disappears.

During my last emissions test my (HC's) were at 480 even though my regulator was set to 30 psi. So something is wrong and I dont know what it is exactly??

Any suggestions, do you think its a bad O2 sensor??

 

Anyone?

 

My brother was getting the same thing in his 93 civic hatchback cx with a D16Z6. It ended up being a fuel problem. He wasen't getting enough and it was messing up the air/fuel ratio....it traveled all the way to the O2 sensor. he got a new fuel pump and that fixed it. so i'm guessing something with a fuel system...

whoa man, dont sleep on those problems or you might be seeing my tail-lights too often

anything with the car bogging means its not getting enuff fuel, so you see how when your starting up if you dont give it enuff gas the car almost wants to turn off and jerks around a bit ? well an accord being a 91 might be at the point for a new fuel pump ..at least get it inspected.

 

I would agree withy you guys. But I changed my fuel pump and installed my FPR. So it doesnt have anything to do with fuel, except the fact that I am getting to much. I think I am going to replace my plugs and see if that eleviates the problem.
Just installed my MSD back again and will change the plugs and see if I still get the O2 light. All this snow isnt helping though..

And dont worry chameleon, even though she is not purfect, she still pacts a deep bite.

 

so we will see.. the beasts get unleashed this march

 

I will be waiting...
