LOVEMY88GT

Well not too long ago i had the exhast changed from the stock H-pipe to a no Cat Mac H-pipe and then got Mac Long Tube Headers. After that i was having major problems. Engine backfiring, major hesitation, and just all around car was ****. I went threw hell to find out what was the problem. Changed Fuel Filter, Put in like 20 bucks worth of fuel injector cleaner, took it to the shop they put new vaccuum lines for under the intake manifold. I brang it home changed throttle sensor, GHR valve and just i was stumped. So a few days later i thought of just unplugging the o2 sensors but keeping them in the pipes. BINGO!!! It works great now. Is the a bad thing or does this type of thing happen more often with 1988 GT?

Thanks

I was thinking about doing this as well, ditching my o2 sensors.
Just forgot to ask it on the boards if it would be ok.

I'm running BBK LT's to a Shorty offroad X

So it's not like im using em, I don't think...

Ya it seems to really do well now. It does not hurt to try it out if you are going to do it.

Maybe you should have disconnected the battery for a few minutes to reset the computer after the pipes were changed. I would try this and then plug the O2 sensors back on as you do need them to operate most efficiently below WOT in most cases.

if you take them off, the computer wont know how well the engine is burning gas, and will not know how much gas to add/remove in the air fuel mixture.

well with your car you may have to move the bung to the headers and put the 02 there
