Is it normal for my 91 miata reads 3900 rpms going 70mph?


It is pretty close, but doing the math....
3900 rpms 5th gear .814 diff gear 4.3 tire rpm = 1114
stock 91 tire size is 185/60-14 circumference = 71.31 inches inches/min=79457 mi/min=1.254 mi/hr=75.23
Completely stock, 3900 rpm gives you 75 mph. not the 70 you were claiming, but you could have smaller then stock tires (one inch less of diameter gives you 72 mph at 3900).
Hope this helps, Lars

2006 gmc 2500 vibration around 60 mph stops when I let off gas


Usually a vibration is due to one or more parts that have become worn or damaged. I'm not sure why you mentioned the tires but don't disregard them unless you know that they are fine. Check for correct inflation (on the door jam), for uneven tread wear, or bubbles and damage.
Other things that can cause a vibration is the front-end needing an alignment, a tire that is unbalanced, worn out steering components (like a wheel-bearing), defective u-joints and/or an unbalanced drive-shaft, or low gear-oil level in the drive-axle can cause damage to the ring & pinion gear. The damage would primarily be on one side. So when you let off the gas pedal the sound goes away. Check as much as you can and let me know how it is going.

2001 F150 supercrew w/ factory towing - No tail lights on trailer


Not sure which fuse you checked.
The Engine Compartment Fuse Panel ( Battery Junction Box / BJB ) is where the fuse is for the trailer tow adapter parking lamps.
Fuse # 5 is the fuse for the parking lamps, and the reversing lamps.

Next is the trailer tow adapter park lamp relay. This is what BJB Fuse #5 feeds, and the coil is operated by the truck's parking lamps. This is also in the BJB, Relay 201, it is the 1/2 size relay.

Not sure what you took a resistance reading from on the trailer tow adapter.

If you want, you can pull the trailer tow park lamp relay, and jumper the normally open contacts, which should provide power at the trailer tow adapters, regardless of the truck's lights.

What ring and pinion ratio should I use for my 2006 f150 4x4 with35x12.50x20 it currently has the stock 373s i want it to get okay fuel economy and still be able to tow a 5000 pound trailer as of now it...


I would leave the gear ratio you have in there. If you go to a 4:11:1 ratio you are going to be turning higher rpms which means more air/fuel mixture being burnt. If you go lower say 3:55:1 you will loose your pulling power.

Need to tow 1999 F250 about 150 miles home. What


If you have a stick shift, you rent a 2 wheel tow dolly and run the front tires onto it and strap it down. Put the truck in neutral and away you go.
If you have an Automatic you want all 4 wheels on a flatbed or tow trailer. You rent a car hauler trailer and piggyback the truck onto the trailer. A good rental will know the weight and rent you the right trailer.

Can I use 205/55/15 tyres on my 1998 Honda Civic?


you can use the requested tire size but from a personal opinion i would not use 205/55/15 i would go with 195/55/15 the wider tire (if your car calls for a 14 in) may cause a rub in the front and cause tread wear or even tire loss. and if the car call for a 14 tire, your speedomator may be of by 7-10 mph at a speed of 55 plus

You are missing all the lights on the rear of the truck ?

The trailer tow adapter runs to a common ground ( see when you take the spare tire down ), that is used for quite a few things.

If you do not have lights on the back of the truck, take a look there, it might not have been bolted back to the frame.

Towing a 5x8 trailer with my Jimmy and now it won't start


Is your battery charged if so!!! I would look for the speed control box it is located under the glove box. It is a little white box with a lot of wires in it. this box is with the computer but there are separate box's. It controls everything from shifting to starting to the gauges in your dash You DO NOT have to replace the computer Good Luck
