'02 3.5 v6 128K runs beautifully trans the same
The gas gauge is on full all the time. When I stop it falls to where it should be after a minute or so then when I resume driving it returns to full - as if the fuel splashing around in the tank is causing it - maybe in combination with a too strong capacitor in parallel with the gauge... ?
The wipers work but not the delay...? Common cause? Fuse? Relay?
What's good to spray onto the leather seats to preserve them?
By looking at it I don't think the 3.5 has a timing belt?
What can you tell me in the way of general heads up on this car?
I'm suffering from a cramped cockpit but otherwise liking this car
Occasionally when I turn into a steep ramp I hear a clunk?

1. It's a common aurora issue. This won't be the correct terminology but there's basically a rheostat type of gauge that clips onto the fuel pump and over time crud builds up on the contacts from the fuel and jacks up the signal. You can pull the fuel pump out and replace that part or perhaps use a brush carefully or contact cleaner. it looks like a little dial with a metal ring which a plastic pointer/ arrow looking piece with a metal tip that makes the contact. These parts are hooked up to the float (sending unit)
2. check fuses and relays - there's a thread on here.
3. Blue Coral or Leather Honey
4. the ECU/PCM controls timimg. I don't think you can change that but if you can you'd mark the serpentine belt.
5. Ummm, I'll let someone else chime in on that but I will say that adding an extra ground wire on the engine can fix all kinds of wacky issues!
6. I don't know...I'm a classic guy all the way.
6. culprits: a bad motor or transmission mount, a weak rear shock absorber or front struts, spare tire jack in the trunk moving around
7. I've learned that cheapest isn't always good. Best to splurge on this at the stealership. FOB is a different story, Amazon and Ebay are your friends.
'98 Aurora w/ Accurate Engines port & polished VIN Y 4.6 bored.30 over, NSP stage 3 PCM, K&N intake, performance exhaust, Razzi skirts, Lund wing, strut bar, custom paint, went on a diet and lost 160 lb.
Fuel Gauge Lance is correct, bad fuel level sender. But on a 17 year old car, if I'm going in, I'm replacing the whole pump assembly.
Wiper Delay Probably the switch (the wiper stalk), possibly the circuit board on the wiper motor.
Leather Seats Saddle soap to clean, then LEXOL conditioner.
Timing Both the 3.5 and the 4.0 use double overhead cams (DOHC) and timing chains.
Heads Up For the 3.5; Oil consumption and/or leaks, cooling issues, head gaskets.
Steering Clunk Anything in the front with a rubber bushing, lol!
Duplicate Key Buy a PK3 blank online, have it cut at a local hardware store. To "program" it: Insert your working key and turn to ON (don't crank). Wait until SECURITY light goes out. Within 10 seconds, remove working key then insert new key and start engine. Done!

I looked for the thread on the wipers - searched but did not find. The wipers do a single cycle when the delay is adjusted but never do another, so it would not seem to be the switch? Might be the circuit board that mounts the r/c timing circuit. Anybody know where that is? This is not the time of year to buy a car - lol Ill probably let this go until spring...
Ordered the key blanks - thanks! Ordered 2 new fobs as well.
I put sea foam in the tank - lets see how good it really is...
Running another ground wire... The main ground runs to the engine, so the starter can work. Another wire would help the stuff that's not on the engine as would loosening then re-tightening the wire that is there now.
Heads Up: The front end suspension is susceptible to harmonic vibrations roughly in the range of 68 - 72 mph. Best solution reported here has been to get "road force balancing" via a Hunter machine when you have the tires/wheels aligned, rotated, and balanced. This is different than old-school bubble balancing. In the past I have asked the shop to bring the balance values down to single digits. Sometimes they have been able to do that.
Heads up: Programmable features Obvious: radio presets; driver chair position; OSRV mirror positions. All programmable by driver. Not-so-obvious: the power steering boost is programmable by the dealership to one of three values: minimum effort (ie, maximum boost), medium effort, most effort (minimum boost). Adjustable: Front fog lamp direction is adjustable in the up-down direction.

do you have to remove the panel to access it? I pulled the rear seat and disconnected the battery to force a computer re-learn and that took care of the light. I thought it was supposed to be easy to use the scanner...?
Where is the relay that fires the delay wipers? I'm pretty sure that's the problem...
Post by arthurpendragon on Jan 26, 2019 9:40:07 GMT -6
yeah - when looking up wiper motors I see they come with delay module...
I'm gonna look for it under the hood. I'll pull the wiring and put it back a couple times... It's so damn cold I haven't removed a tail light to replace a bulb! This just isn't a smart time to buy a car. But when opportunity knocks...
The po said he bought it at an auction then fixed it up. SURE, I thought. Now I see it has 4 wheels of new brakes and a brand new battery, and not a cheap one, duralast.
After the sea foam I used a bottle of regain (fuel injector cleaner) high-mileage. My usual ritual when buying a car. That motor purrrrs! Fuel filter on order - the seafoam almost plugged it - as usual.
