Then I am one very fortunate technician, as my customers drive more than 3 hours to get to me, and gladly accept a loaner car. Im VERY LUCKY indeed. Paul

HI there, AND BE PATIENT, DO NOT WAIT FOR THE VEHICLE. In order for this calibration to be done correctly, it must be allowed to run its course AND NOT STOPPED. Drop the car, leave it for the day and the programming will work. IT can take up to 2.5 hours to accurately perform, based on...

HI there, Vent line disconnected will cause your issue with fumes as they vapor is not being directed to the charcoal canister. The removed the rear subframe to get the differential out and saw the issue, and its done, that is excellent. As for the 'major problem' with the tanks, I digress a...

HI there, I have done a few, both LT1 and LT4, I have one common denominator. INCORRECT BREAK IN PROCEDURES! I have not seen any with metal filings in oil filter assemblies or the like, although I have heard that a few have occurred in early 2014. My 2 LT4 and 3 LT1 were modified with...

HI there, There are many different reasons for any number of issues with the easy exit seats. #1, if you push the easy exit button on the door, what happens? #2, do you have anything behind the seat back? #3, can you get your normal memory package to work?? In other words, does it know...

HI there, That product is not added to the fuel tank, NEVER put that in the fuel tank. That product is atomized at the front of the throttle body as the engine is running and is pulled through the intake system with incoming air and will wash the backs of the valves as it is pulled into the...

HI there, They are absolutely correct, and here are the reasons why. #1, this engine, Gen 5 small block is unlike ANY other engine that came before it because of the spark ignited direct injection. #2, c5/c6 engines ran at 55-61 psi at the injector, your LT1 runs at idle anywhere from 400-600...

HI there, Yes, I read all of it. The analog signal is what you should read, and rotation of the sensor will indicate your home position. 2.5 volts, and if you do NOT have an accurate digital multimeter or a good ground source, you will create this issue. Was the ground hooked up at the EBTCM...

HI there, Early production vehicles, especially a first year new model will have its share of issues. 2005 were the same way, and 1997. However, I would say that being around for all 3 generation roll outs, this c7 seemed very much better than previous generations. Plus, our technical...

HI there, Oil windage is due to the fact that oil is still slung around the crankcase, vapor with oil droplets is still present that is pulled into the PCV system for burning. Many people believe that this is the ONLY factor with carbon fouling of the intake valve, this is incorrect. If PCV...

HI there, Its actually quite simple. Your steering wheel was turned while your steering gear/rack and pinion were disconnected. You need 2.5 volts when the steering wheel is straight ahead. You do not have that, and that is why your codes are setting. Disconnect the intermediate steering...

HI there, Every engine is hand assembled and all parts are machined tolerance. Air tools that are torque calibrated and recorded are used in both facilities. Having worked FOR Ferrari, yes its an amazing machine and you PAY for that hand tolerance, hand assembled craftsmanship. GM can give...

HI there, Normally, I will use OTC 7448 canister to pressurize the cleaner and fog the system while the engine is running. Pressure is over 65 psi to enable finer atomization to get the cleaner to the backs of the valves. I have used a number of different cleaners to attempt to find one that...

Factors affect results of intake valve deposits HI there, Lets talk about this in more simple terms. Intake valve deposits come from DIFFERENT factors that come together in a perfect storm. These factors include, but are NOT limited to, oil quality, fuel quality, PCV SYSTEM FUNCTION...

HI there, The fan control module is actually TOLD to turn the fan on based on the engine control module providing input for on signal. The data from the engine control module will need to be read and you wil have to also make sure that the signal is being SENT from the ECM to the fan control...

HI there, Along those same lines, YOU MUST have this procedure done on an alignment rack that allows tire slippage and movement WHILE the spring tension is adjusted. And you must ALWAYS ALWAYS ALWAYS realign your vehicle afterwards. You move one thing on a Corvette spring setting, this...

HI there, There are a few possible scenarios here. There is a switch in the buckle to let the module know its latched #1, is the seat belt buckle pigtail not connected to the wiring under the seat???? #2, did anyone have the seat out at anytime and maybe didn't connect the switch???? If...

HI there, There are also other factors not being mentioned here that need to be addressed. The CHASSIS CONTROL MODULE is the gateway module to all interaction between eLSD, ABS/TCS/AH, ECM, and I forgot EPS and F55 Magnetic ride control. This is not just clamping force of the clutch within...

HI there, No, there has never been warranty like that on any factory equipped shock absorber, magnetic ride control or not. HOWEVER, if you purchase GM shock absorbers at a dealer installed at a GM service dealership, they ARE covered under certified service warranty for life. Allthebest,Paul

Hi there, YOUR VIN will tell me alot about your availability of a programming update for the infotainment system on this car. I would say probably you do have some type of update. Allthebest, Paul
