I put my headers abd exhaust on last night and the downpipes didnt have the sensor bung for the O2s'. Its an 88 SD, how will this effect my ride untill i get some bungs put it?

 

When I recently put new shorty headers in my 88I accidently busted one of my 02plugs off(on the passenger side)and I couldn't get it out no matter how hot I heated it. So what I did is plug the hole. I've been driving with only one 02sensor ever since with absolutely no problems. I'm not saying that it's O.K. to be driving like that,I do plan on fixing it,but right now I'm not having any codes popping up and the car runs just fine. I'm sure someone smater than I will be able to give you a better answer-I'm just letting you know of my experience with this topic

 

i havnt drove mine yet but i let it idle for a few, then i mashed the gas and i had no probs. hopefully i can roll it for a min untill i get it fixed also. Thanks!

 

If you must people have. It definitly isn't optimal and you car won't run great. You will also get crappy gas mileage, it will put you into closed loop I believe. Get it fixed ASAP

 

My gas milage hasn't changed in fact I think it's better.I will be fixing it though when I get time.
