Question:

I have a 1999 Ford F350 DRW. Where is the rear ABS sensor located?

Answer:

Should be located in the rear differential. Look for the electrical wire going to it. This is a common failure part for the Fords…
 

The Chevy 3.1 L engine as well as the Chevy 3.4 L engine that use Dex Cool Anti-freeze are known for lower intake manifold gasket leaks. Pressure testing the coolant system can usually confirm if your lower intake manifold is leaking or not. If it leaking, you will want to replace it right away to prevent further damage. There are complete instruction below for replacing the lower intake manifold gasket on your 3.1 L engine.

DETAILED REPLACEMENT INSTRUCTIONS FOR LOWER INTAKE MANIFOLD GASKET

1. Check for air in the brake hydraulic system. Inspect the brake hydraulic seals, fluid lines and related components for fluid leaks. Remove the air from the brake system by bleeding the brakes. Be sure to use fresh brake fluid that meets the manufacturer’s recommended standards.
2. Check for an internally restricted flexible brake hydraulic hose. Replace the hose and flush the brake system.
3. Check for a seizing brake hydraulic component such as a brake caliper. Check the caliper piston for surface damage such as rust, and measure for out-of-round wear and caliper-to-piston clearance. Overhaul or replace failed parts and flush the brake system.
4. Check the vehicle’s alignment and inspect for suspension wear. Replace worn bushings, ball joints and set alignment to the manufacturer’s specifications.
5. If the brake system uses drum brakes front or rear, check the brake adjustment. Inspect for seized adjusters and clean or replace, then properly adjust.

Trouble Shooting Your Brake System

Question:

I have a 1999 Toyota 4Runner with the 6 cyl. When the engine heats up it runs real rough and the engine light comes on (almost like it was running on 5 cyl.) It feels like it will stall when you come to a stop and it shakes bad. Also has no power when in overdrive unless I hit the gas hard. When I rev the engine it seems to sound great but when the rpm”s drop it runs rough again. I replaced the fuel filter, air filter and plugs. But it still runs rough when hot? 

Answer:

Remove the Spark Plugs and verify the vehicle has the correct Spark Plugs installed. The engine requires the use of dual ground electrode Spark Plugs. If the incorrect Spark Plugs are installed, the vehicle can run poor and can set misfire codes. Always install the correct dual electrode Nippondenso Spark Plugs # K16TR11 or NGK spark plugs # BKR5EKB-11. Then test drive and verify the engine misfire has been repaired. They also have a lot of MAF sensor problems that is the most common fault. Use a Scan Tool to determine if you have any existing odes. 

Question:

I have a 1996 Ford Van with the check engine light on. How do I find the right Scan Tool for my car?

Answer:

A scan tool with enhanced diagnostics can save your a lot of time and worry and allow you to do most of the troubleshooting from the drivers seat.

In my shop, we replace the egr valve, the egr regulator and the egr sensor and this will fix the issue. You will want to get the parts from your local Ford dealers parts dept. Shouldn’t take an hour to replace the parts if you work on cars. If you do not, you may want to have it done for you.

In Short the answer is YES. There’s no question air-conditioning makes extra work for the engine, increasing fuel use. But car air conditioners are much more efficient today than they used to be. In around-town driving, using the A/C will drop fuel economy by about a mile a gallon. If you have an Older car ( pre-1996 ) then the fuel consumption will be greater.

Using the A/c while driving on the highway may not make a difference when compared to driving with the windows down. When the windows are down it creates drag which will lower your fuel mileage, making A/C use the more efficient choice at high speeds.

At most speeds and in most vehicles, A/C use drains slightly more fuel than driving with the windows down, contends David Champion, head of auto testing for Consumer Reports. “My final take on is that it’s very close,” says Phil Reed, consumer advice editor for Edmunds.com. “It’s hard to measure the difference and every vehicle is different.”

The best choice – if temperature and humidity allow – is to keep the windows rolled up and to turn the A/C compressor off. You can keep the fans running to blow in air from the outside, but your car will be as aerodynamic as possible while still letting you breathe. You will save gas, but the fuel economy improvement will be slight.

Question;

I had the code pulled on my 2002 Toyota Camry (4 cylinder) and it came back P0135. I was told this was an oxygen sensor. Is this the sensor that is located in the engine compartment on the manifold? Or is it next to the catalytic converter on the bottom of the car?

Answer:

P0135 is a malfunction in the heater circuit of the O2 sensor referred to as Bank 1 Sensor 1. It is located in the manifold.
