Iove that there is a "What did you do to your xxxx car today?" thread in every single car forum I've ever been a part of

I drove it hard again. she's just smooth on power. Never mind the piss poor economy... my 4Runner got 12mpg any way I drove it! and that was the 3.0 manual. slow as hell. Even now the ZJ makes almost 14mpg driven hard. and it's about twice the displacement!

Is that hand-calc mpg or from the overhead? In the brutally cold dead of winter, I'm down to about 11 mpg around town in the niner while trying to be somewhat efficient. In the spring/summer/fall, it would be about 13 - 14 mpg in the same driving. OTOH, as long as I don't drive too inefficiently in general, beating on it whenever I need to accelerate doesn't seem to hurt the mileage much (if at all).

TV cable is adjusted properly, though I haven't messed with the bands. It has 81,500 miles on it.

I ordered a buncha stuff for my ZJ today. Can't wait to get it all on!!!

http://www.jeepforum.com/forum/f13/p...-jeep-2127281/

• Bar pin eliminators for front shocks (hopefully cure some of the remaining knocking noises)
• Front/rear coil isolators (stock ones are shot)
• Coil spacers (temporarily using 2" coil spacers on my 3.5" Rubicon Express springs to end up on 5.5" with short arms in the rear on stock drive shaft, and long arms in the front with u-joint shaft)
• Front/rear Doetsch Tech 8000 Prerunner shocks (need new shocks to support additional lift)
• Iron Rock Offroad front long arm kit with bolt on sub frame (this will replace my bent and hard to find OEM transmission crossmember while also allowing me much more flex in the front and keeping the axle more centered in the wheel well to resolve clearance issues. Long arms will also work better with my IRO OTK steering.)
• JKS quicker disconnects for front sway bar (needed to allow the sway bar to be connected with the additional lift, and I went with JKS because they are easier to connect/disconnect due to tapered ends)
• Front/rear extended stainless steel brake lines (additional lift and flex requires longer/stronger brake lines)
• Water pump (preventative maintenance, don't want to overheat on the trails!)
• Upper/lower radiator hoses (why have a new water pump with old crusty hoses?)
• Timing cover (mine has a large hole in it which we believe is from an idler pulley that flew around in the engine bay once)
• Timing chain (if replacing the cover, may as well replace the timing chain and gears)
• Oil pump (preventative - going to higher pressure/volume than stock)
• Front/rear crank seals (no more oil leaks!)
• Thermostat with fail safe (if the thermostat malfunctions it will stay open instead of closed)
• Aluminum thermostat housing (preventative to reduce chance of leaks)
• Power steering pump (no more leaks, help with the large tires)
• Full headlight/marker/turn signal kit (replace dull/faded/broken front lights)

I changed my trans fluid around 70-75k miles and adjusted the bands. It made a huge difference in performance. I also adjusted my TV about a year later when I read about it on here. My ZJ shifts like it's new now. The 44RE is enough for the power of the 5.2. Try some maintenance before you throw a bunch of money at a rebuild or replacement trans.

I agree. I had the exact same issues. Mine died going down the highway, and would crank, but never fired up. Replaced regulator, fuel pump, filters, just to realize it was a cheap ignition coil.

What year viper keys? My buddy did this and I'm mad jealous. I'm totally copying. Lol.

There have been some other issues of concern, but I'm gonna try that before I go for a rebuild.

Bear in mind, all of my prior experience with the TorqueFlite transmissions of the 1990s has been with the massive failure rate I've observed. I assume these aren't much better than 4L30s.

put some more seafoam in the tank

im thinking of doing this every 3 months and running the tank out before every oil change but i dont want to do it too often

anyone think 3 - 4 oz of it a tank of gas a week or so before an oil change is going to hurt it ?

If you get a fail safe thermostat.. You might as well just run your ZJ WITHOUT ANY THERMOSTAT! They fail instantly.

Thanks for the heads up on the fail safe thermostats guys. I'll be putting a standard one in and will just keep a spare in my toolbox.
