this is driving me nuts! ( no pun intented)

[vibrantred5.0]

So I got a used H-pipe from a guy( offroad) and I'm now taking off the header-midpipe nuts......I have all three off except for the passengers side bottom one.....its driving me crazy!!! The O2 sensor is directly in the way so I'm using a swivlejoint socket thing.....but I think I'm bending the bolt with that..... I've already doused it with PB blaster.....wrenched on it for forever.....why won't it come off? its rusting alot.....but the other ones were the same and they came off after a little muscle....this one just won't though.....its not stripped....it just won't turn...help please

tried heat yet? get a torch or just cover it with pbblaster and leave it over night.

I soaked it.....but I got a 2 foot wrench and it sheered the bolt right off....so I'll need a new one of those....Holy Shit the oe midpipe is heavy!

take the 02 sensor out and ull be able to get the socket in there alot better.. worked for me and the 02 sensor came out easier than i thought it would.

yeah I couldn't get the O2 sensor off ....too greasy....So I won't have a "check engine" light on all the time now will I? there are holes in the offroad pipe for the sensors....so they're in there.....

now you'll have fun getting that broken stud ou

If it is a offroad mid pipe, then yes you will have a check engine light

If it is a offroad mid pipe, then yes you will have a check engine light

Only if he doesn't put the O2 sensors in. 94/95 GTs don't trigger CEL with off-road pipes, only 96-up does, thus why you either need to turn the back 2 O2 sensors off, or get MIL eliminators, which isn't need in this case.

I got the day off tomorrow so I plan to get the midpipe on then......I already have the 02 sensors in the midpipe....so I don't see why the check engine light will be on when I get every installed...

I broke three of my studs lol just drilled and got new ones. I shouldve just cut them in the first place instead of wasting time wrenching lol

The O2 sensors are before the cats so the ecu does not know if there are cats or not, hence no CEL as stated

 

[vibrantred5.0]

alrighty....i got everything installed yesterday....but my check engine light comes on every once and a while.....some times it just comes on or 10 seconds...some times for 5 minutes..

Have you checked to see what the code is?

Ya scan it and see what comes up. The obdI scanners are cheap
