okay i got a little problem guys. My car keeps bogging, so i checked my msd wires to see if they are connected or not since they like to get loose sometimes and everything was cool. I pulled the plugs out and they are black, im going to replace them once i get off work but im not sure this will help. Seems like ive been wasting a lot of gas lately and it just started to bog. My car is daily driven and has been driven open header for a quite a while now. Could running open header cause the o2 sensor to go bad and make me run rich? i tried reseting the ecu but no luck. Any suggestions? ohh yea its a 98 dx hatchback with b18c with IM, intake, and fuel pump. Your help is appriciated.

 

BUMP

 

Sounds like bad 02 sensor to me :/

 

yea thats what i was thinking, just wanna make sure

 

got any CEL?

 

NOPE

 

thats weird cause if something was wrong with the o2 then CEL will come up right?

 

Sounds like an ignition problem...I had the same problem too where the gas mileage was all over the wall, and I would have backfire issues.....I alliviated the problem with new plugs...the plugs i had prior to the exchange were supposedly new but seemed faulty. With the new plugs the car worked like a dream. Never hurts to borrow plugs from a friend.

 

yea imma put new plugs in tommorow at the track

 

The CEL wont go off til the O2 is completely toast. I replaced mine with a universal one and the rich prob went away
