No turn signals.

2003 Buick Century had a problem with blinkers that would stop working sometimes. The customer then stated that if they move the tilt steering wheel the blinkers start to work again. After checking the basics I pulled the column panelling off. I found a wire that had been rubbed through on the harness.

Back in black

With it being super hot, there's many ways to stay cool. Driving a Acura NSX is one way. Or fixing the A/C is another. This car a had a high side restriction in the system some were. We forced the Freon to get it to evacuate and off to charging!. The NSX design is streamline and a rear engine car. The fittings for the system are up front in the trunk(funny right) and the rest of the system is in the rear. We had a hard time getting this to charge for this reason. All and all it was a good learning experience and nice to work on a true sports car from the near past.

Intake on a Ford 4.6

These motors have a bad problem with the plastic intakes cracking on the thermostat housing. They can cause running problems, check engine lights for a po171 which is a lean code, and will cause tie car to over heat. When doing this repair be careful not to drop anything down into the intake. The parts house or local Ford dealer should have the updated manifold.

Summer Heat

With the heat rising its always a good idea to get tie A/C checked. Just because its blowing cool doesn't mean its cold. If you transport kids, or toting you precious pets, we want you and them to be safe from the elements. A lot of places will check you A/C for a small fee. Its worth it to stay cool and keep everybody safe.

S10 crank no start.

We had a 2001 Chevrolet S10 that would turn over but not start. We check fuel pressure and found it was 45 psi. The range was 41-47 so it was ok. We then pulled a spark plug wire off and found we had no spark when cranking. The ignition control module is what sends a signal to the computer to fire the coils. We tested this by looking for a voltage signal. We had 11.87 volts. So this was ok. Next we turned to the crankshaft position sensor. We found that it was giving a signal about every 10 to 12 crank revolutions. Hmmmm. It should show every revolution on the scan tool. We put a new crankshaft sensor in and problem solved. This is a short hand write up of a hour diagnose.

Spark plug play by play.

When installment of spark plugs is required:

Always make sure you have the right plugs. Go can give any parts house your vehicle identification number or vin. They can use this to give you the correct parts you need.

Also rember to properly gap the plugs buy using a feeler gauge. You can find the correct gap by looking under the hood or the owners manual.

NEVER over tighten the plugs or you can damage the cylinder heads.

Remove any debris that could fall down in the spark plug holes.

Before starting the motor check your work.
