First, I just got 9mpg on my last 60 miles. There may have been a bit too much idling, and a little bit of jack rabbiting on some starts, but this is hideous. This is after I had a seized front caliper fixed which should have increased my mileage. I want to correct this. Plus, my engine is very growly. I don't think it's an exhaust leak, but not sure what else it could be. Want to get this fixed up.

My belts squeak. After I tighten them a bit what can I spray on them to keep them from doing this. They are new from last year, only 5000 miles, and one started getting a bit worn on the side (very minor). They squeak a hell of a lot more since I hit a sign and de-greased the engine.

Taking off the running boards--do I need mud flaps behind my front wheels? Any ideas for new flares?

How much should a stock new rear bumper cost? Mine's rust city this year.

Finally, I'm getting a lot of suspension bounce. If I give it a good push up front it bounces about three times. I'd like to have this done front and back, and maybe lift it up a bit. I don't want a raise that requires other mods, and I don't want expensive, custom springs or shocks. Just a stiff ride and a small height advantage. Getting new tires at the same time (BFG AT K/Os I believe).

Gonna do a new filler pipe to fix code throwing, and if that fails am I looking at a new charcoal filter as well later this year?

Engine tune-up/clean, exhaust welds, squeaky belts [need tightened (cheap), ****ed up pulleys (not good)], flaps(?), flares, rear bumper, shocks and springs and spacers, filler pipe, labour. How much?

Also, after being up to my running boards/doors in a mud puddle and spinning to get out, and then hosing off underneath big time to clean it up, is there anywhere I should pay special attention to and re-lube?

Belts were fixed with belt dressing. :withstupid:



Now it's just:

1) Poor mileage and noisy idle and acceleration.
2) Best shocks and springs, with a little added lift.
3) Any lube to be done underneath after mud and hardcore washing underneath.
 
What have you done to help your mileage? A common list would be the following:

1) Change sparkplugs and wires (wires aren't really NEEDED to be changed but if you want to, do it).

2) Clean Throttle body and Idle Air control valve

3) Clean Mass Air Flow sensor

4) Inspect/Replace front O2 sensor with stock Denso unit

5) Make sure your air filter is clean

6) Change your fuel filter

Theres a few more than that, but thats where i'd start. If nothing helps, then you'd need to get an OBD2 scanner and start seeing what is wrong.

For your 2nd question, theres a ton of info on there. Check out Toytech lifts or Sonoran Steel.

You mentioned you want a stiff ride. KYB gas adjust shocks. Ive had them for about 8 months, and theyre ridiculous. Too stiff in my opinion. Theyre also long enough to a lift. They seem to get good reviews for reliability, and theyre cheaper than bilsteins. Though I will probably switch to with bilsteins eventually.

yeah he has about covered it with the tune up. that will help a lot maybe run a bottle of seafoam through the intake and one in the fuel tank and let that stuff work its black magic and wizardry... and yeah the drive shafts and U joints are the only thing that are greaseable down there
