It is at the opening of the throttle body where the air enters from the filter. Sounds like you have a real 'poser' of a problem there. E-mail me at "bulruq@yahoo.com" with a description of your problem and I'll try to help.

Mine gets a little better than 22 MPG driving around town when driving easy. I get around 30 MPG on the highway using cruise control and doing 65 MPH. BUT, it has a LOT to do with how heavy your foot is on the gas pedal. If you have a heavy foot and drive the car hard, it goes down dramatically. Drive it easy and it's surprisingly good. When I first got mine (used), it only got about 18 MPG around town. It intermittently ran slightly rough on startup but showed no problems when diagnostics were done. Knowing that all other parts were good, I took a chance and replaced the coil pack. Replacing the coil pack fixed the roughness and improved the mileage considerably.

Changing spark plugs with the correct heat range plugs won't affect the running temperature of the engine. If you had a fouled ploug or otherwise inoperative plug and picked up a cylinder that wasn't operating before the plug change the engine might operate at a higher temperature that would be normal for the engine. If you used the wrong plugs for the engine or cross threaded them or crossed plug wires you might see an increase in temperature and feel a decrease in performance. How hot is your engine running?

It has a lot to do with the fact that the heat provided when you turn the heater on comes from the engine. the faster your engine is reving the more heat you'll get. Next time try putting the car in neutral and revving the engine. that should get you some more heat.

My 1990 E350 has 235 85 R 16 size tires.

Since you're checking the resistor, I would assume you checked the fuse/relay for the blower motor. If not check that. If you have then there would be an open wire between the relay and the resistor.

On a 1997 Dodge Ram 1500 Van, open the hood. The resistor assembly is at your upper left on the heater/AC ducting, with a cable of wires going to it, a trapezoidal plate about 2" x 3" held on by two small screws. Inside, it has a shrouded set of three resistors plus an unknown gidget that looks like a resistor about 0.1" x 0.5". On my van, the resistors are fine but the gidget is open circuit, or else it's a capacitor to stop radio interference. I also have a blown out motor (open circuit), and a shredded up flimsy, chintzy plastic fan. The ducting was clean, no sign of debris to block the fan except for pieces of fan blades. The fan motor is about a foot below the resistor, hard to get at but better than on most vehicles. R B Britton/ Hetex Engines Inc.

Separation of the ethanol due to water in the gasoline.

The most likely cause is a defective brake light switch; It is located towards the top of the brake pedal.

Blown fuse, defective heater control switch, bad resistor pack, loose or disconnected wire.

The 2004 Trailblazer does not have plug wires. It has a coil pack per cylinder that connects direct to the spark plugs.

4, four, quatro, apat..

You will need 12 bocsh spark plugs. These engines have 2 spark plugs per cylinder.

i found an article for jbody z24's which required removing the entire dashboard to switch the light. two torx screws near the wheel, and the whole thing basically pulls straight out.

i think it was at www.v6z24.com and was in the faq section
