Jim Taddei

Oakland, CA

I have been in the automotive field since 1975 and have accumulated over 25 years of experience with General Motors products achieving the designation as a GM Master Technician. I am also currently certified and an ASE Master Technician, and hold an Advanced California Smog Check License. I have been the lead technician and team leader at a multi-line dealership. After leaving the dealership I spent a couple of years working in an independent shop and now find myself applying my experience for your benefit at RepairPal. My training includes numerous GM classes and college courses which resulted in an AA degree in Automotive Technology.

Question Answered: 

When Hydrocarbon (HC) emissions are high, that is a result of an engine misfire, excess fuel entering the cylinders, or a catalytic convertor not working as well as it should. Replacing the plugs is a good place to start, perhaps the 02 sensor as well if it is not to expensive and relatively easy to replace. Make sure you make a good freeway run before getting the vehicle tested, you want to be sure the catalytic convertor is fully warmed up and functioning at its best. If you still don't pass you can plug the results of the test into a Lamda calculator - http://www.smogsite.com/calculators.html#lambda. This calculation will help determine if the problem is to much fuel or something else (misfire or tired cat).

As far as I know, the front wheel speed sensor is part of the hub assembly. Talk with your local parts store to confirm this.

Question Answered: 

It is not uncommon for the EGR passage at the intake manifold (behind the throttle body) to become plugged. Commonly, the throttle body and EGR valve will need to be removed to clear the passage. I do not recall a P1113 code for this vehicle, perhaps you have the number wrong. It sounds like the cooling system needs a good flushing to remove all the brown sludge. If the engine is still overheating once that is done, the cooling system should be properly diagnosed before any repairs are made.

I have seen problems with backlighting failure on the dash & switches. Most commonly the affected component will require replacement as individual bulbs are not easily replaceable.

Question Answered: 

The temp gauge signal comes from the PCM which relays the signal from the engine temperature sensor. I would suspect the temp gauge is no longer working due to an internal cluster fault. If the coolant sensor signal to the PCM is OK when monitored with a scan tool, repair or replacement of the instrument panel cluster will be necessary. Please note if the original cluster is repaired, no programming should be necessary. If the cluster is replaced, the new cluster will require programming.

Question Answered: 

It is not uncommon for the temperature gauge to rise a bit when the vehicle is stopped, before the cooling fan turns on. If the gauge is going in to the red, it could be that the electric cooling fan is not working properly.
