I had to rebuild the NSS on my 97 a few days ago. It's a really simple process as long as you're careful while pulling the contacts and springs out... I would also suggest tying a piece of string to the plug when you remove the sensor so that you have something to pull it back into the engine...

Of course Joe is right, a fan clutch would be a likely culprit as well...

The coolant temp will rise after shutting the engine down. Once you shut off the motor, the coolant stops flowing and will absorb heat from the block/head, causing the temp to rise. That's nothing unusual. As for the overheating issue, it sounds like you have air in the system. You may want to...

I've always steamed metal tanks... I guess you could use a pressure washer on a low setting with an angled nozzle to spray it out repeatedly, and then dry it out really well and spray some ether in it to draw out any remaining moisture. Make sure everything is completely dry before reinstalling...

I've never used a Carter pump, but I've had good luck with Walbro units on several other vehicles. If you look, you can find a new unit with the intallation kit for just under $100 too...

I've never noticed the rattling sound, but I haven't had this XJ very long and I haven't driven the '89 in quite a while.... If the fuel that got dumped into the intake was metered and accounted for, it could possibly help combustion, but on this system, when the valve purges it releases an...

Yeah, I had an OBDI controlled F-Body at one point that had issues with an EGR setup similar to the RENIX XJ's. I wound up getting rid of the system and tuning it out of the PCM, and it really had no effect when they hooked the sniffer up for emmisions testing... As far as the EVAP system...

Well if mine winds up being bad, I'll take a hacksaw to it and upload pictures...

Are all of the valvetrain components that went back in stock? Did you go to a roller rocker, or switch to an aftermarket lifter or valvespring? It's not unheard of to get a valvespring with a defect from the factory. I won't name anyone, but at least one of the big manufacturers has had a bit of...

All Night Long - Lionel Richie

Thanks for the info, hopefully I'll get it figured out in the morning... Just out of curiosity, how does the FPR operate if it's not vacuum controlled? I've never had the tank out of an XJ before, so I have no idea what kind of system I'm even dealing with there...

I know it's tough in that field right now. I'm also in the electrical business, though I've been more on the engineering/sales side of things... I've been laid off for quite a while now, and have been travelling all over the country looking for job opportunities. Right now there are a lot of...

1. I understand this, and I guess I should have elaborated on that a bit. My thinking was that OBDII may have been overcompensating for a high idle condition resulting in a low actual idle and causing the IAC counts to move out of range. 2. It could be running rich. I have a wideband, but it's...

I'm hoping some of you guys could give me a quick helping hand here. I've got a 97 with the 4.0/AW4 combo. I bought it recently, knowing it had a few small issues, and now I'm having trouble buttoning up the last few bits. It acts like it has a vacuum leak. It seems to idle low, though I'm one...

Nevermind, I hadn't refreshed since I confirmed my email address... That fixed it.

Ok, I figured this was as good a place as any for a first post on the forum... I'm obviously new to the board, but I've spent some time on a few other forums and feel like an idiot for even asking this, but where is the search button? It seems like it would normally be at the top of the page...
