I could swear that the rear 02's are wired the same as the front - @ the plug end on the sensor itself .

So I wired it the same . I didn't get a chance to look at the old ones before I wired new ones -(don't ask), so I was kind of lost there..

Can anybody confirm the wiring is the same as the front at the plug end of the sensor itself?

I'm getting PO420 and 430 codes , so I want to double check I wired that correctly.

Thanx

 

brew, not sure about the wiring, can look tomorrow. Are you thinking that the new cats are setting the codes? I saw somewhere about O2 spacers to help with the CEL problem. Found the link: http://www.scoobymods.com/forums/showthread.php?t=5468

 

I never would have found that , nor have I seen anything like that - yea , his configuration is like mine. Mann , how did anyone figure out that fix?

Great torkum , you may have saved me a ton of work ..

I owe yuh..

 

Hope it works cause I'm going with headers [now longtube] and highflow cats. In my research I run across this info and thought it might be valuable if the codes came up.

 

FWIW, cat efficiency codes are NOT caused by faulty downstreams....

The spark plug anti-foulers or MIL eliminators will help in getting rid of those codes, though.

I buy the rear sensors, longer wires, to use in the front so they are the same.

Mann , thanx allot for the info fellas , that really helps.

Yea , I dumped about a gallon Windex on the pipes - shoved an air hose in the exit only hole and put about about 10 lbs to her - She blew bubbles at just about every joint. - Cheap **** clamps..

I have a bag full of those GOOD band clamps this time and I 'm going to eliminate a few seams for a quick fix I hope - That way , I can take my time learning how to weld - Think I'm going with a Miller wire feed , can't wait for that !!..

It was leaking enough to cause the codes is what I'm thinking - That was in JMC's list of posibilities, I bet that's the problem .

Mann , those cheap muffler clamps are junk !! The clamps I just picked up are guaranteed not to leak - 10 bucks apiece tho Well, this should be good enough for now..

My rear O2's are right then

Thanks again guys, that really helped me out.

 

damn all the money in them clamps lol ur better off getting it welded at a shop.

 

Nah , I'm learning to many invaluable lessons - Like - What NOT to do


I'm determined now - next time I pressurize it- the pistons are going to start shaking and the plugs will go into launch mode.. - She's ain't going to leak a peep from these pipes this time around....
