That's all fine and dandy, but if you complete the mod in my Tips, it's nothing to be concerned about.
The issue with Renix MAP sensor lines has nothing to do with that. Small plastic tube with rubber elbows at both MAP and throttle body, while eliminating that POS plug at the throttle body works fine.
But, here we go again. Complicating the living **** out of non-issues and not addressing the issue at hand that needs attention.

 

I honestly don't even know what the conversation at hand was. Just a bit of Google-fu that I thought I'd share for anyone interested in the subject.

 

But you sure put enough stock in it to blindly believe it and post it here.

Anytime some jackhole on a forum starts talking like a Harvard professor, I tune them out.

I'll take experience over theory any day of the week and twice on Sunday.

 

I'm glad you did. Thank you.

 

BTW, what torque was used on the oxygen sensor?
What's the ohms value on the new one?

 

I responded to the torque question already. I don’t understand all the anger over me asking a question. I’m driving to work I don’t have time to check the new sensor today.

 

You asked for a link... (hard to identify sarcasm on the internet in light of your 2nd to last post. If NASA isn't a viable source, ...)

In summary, RTV kills sensors, vacuum tubing size makes a small difference and you torque O2 senors until they're tight.

 

@Jim Malcolm I used Permatex 82194 Ultra Grey which is supposed to be safe for sensors. I assume the acetone in other RTV compounds is what creates the issue? This RTV does not use acetone.

 

I didn't see the torque question answered. Sorry. What was it? Link? I just got up and had a flurry of questions about MAP sensors, RTV, vacuum bull****, and hay-okey repairs, NASA and possibly replacing perfectly good oxygen sensors.
That stuff generated questions from me. And responses from others. And more questions from others.
When are you going to complete Tip 31? when you do, I'm sure more questions will arise. The NAPA fitting part numbers have changed. I don't have time to figure out the new numbers. Could you note the new numbers from the local parts store? Doesn't have to be NAPA. Then I can update the part numbers in my Tip 31.

 

NASA is a very viable source. For aerospace. Not jeeps. I wasn't being sarcastic, I truly appreciate the link. It completely backs up my point.

Some wannabe PhD mechanic read a NASA paper online, and posted it because he "found similarities" in them, so he tried to sound smart on a forum while talking out of his ***.

The engineers at jeep, while not NASA rocket scientists, have already done the work for us...their design has proven solid in the decades of proven performance.

Just replace the MAP sensor tube with the right one. FFS

 

@roninofako there is no “right” one available anymore so I either need to find one at a junkyard (none of the ones around me have any Jeeps), find someone selling a used one online, or remove the intake, tap threads, and do a DIY replacement. I’m happy to do the last one but that takes time and I don’t have a ton of time at the moment.

The RTV I used to try and tighten up the PO’s electrical tape job is Permatex Ultra Grey which is labeled as sensor-safe and doesn’t give off acetone. I would assume acetone is what creates the sensor issue with some RTV compounds? Either way, it’s specifically labeled as sensor-safe.

 

@cruiser54 your part numbers still appear to be correct; which part number did you think had changed?

 

"Should" be good. Implement Cruiser's fix as-soon-as-reasonably possible. It's the "proper" long-term fix. Who knows how long a JY or FleaBay replacement will last.

The O2 sensor has the biggest impact of fuel economy with highway driving. You just replaced it, see if it fixes your issue before opening too many cans of worms. But do implement every single one of Cruiser's recommendations as time and money allow.

 

@Jim Malcolm That’s the plan. I’ve never tapped a new thread before. Any tips you can share so I don’t mangle the intake?

 

Well, live with it I guess until you find the time. Then do tip 31.
