Yes the port you connected to when you took the pressure reading is the same port to connect the cleaner to. Another thing you may want to consider doing is what people on the forums call the "big 3" which is replacing the grounds from the battery to engine, battery to frame and battery to...

Yes this is the spider system inside the upper intake, but there is a service port near where the fuel line attaches to the spider injector system. I would just try the seafoam treatment first before looking into the professional treatment.

If you go to NAPA they can sell you the kit just ask for the 3m fuel injector cleaner kit they will know what you need. Or you may just want to take it to a competent repair shop in your area they can perform the service for you. Check with the Chevy dealer they may not be too bad on their...

Have you ever done a professional fuel injector service on your truck? This is the one shops do with a 3m kit or similar that has a pressurized can that connects to the service port on the fuel rail. You disconnect the fuel pump relay and run the truck off the can. I would try this as a next...

Trying to make sense of the readings from the oxygen sensors from a scan tool is futile. The readings are buffered by the scan tool software, so basically what you are looking for is sensor one should switch between a high and low reading and sensor 2 should not switch between high and low or...

I thought some of you might be interested to see a project I have been working on this summer. I have always liked the beauty and corrosion resistance of stainless steel, and decided to convert my Limited over to stainless bolts. Some bolts I will not convert for obvious safety design reasons...

One more thing to add... If you are getting similar readings on sensors for sensors 1 and 2 (the o2 sensor after the catalytic converter showing the same changes in voltage as the o2 sensor before the catalytic converter) this tells me the catalytic converter is not doing its job. This could be...

In the GM service manual for this vehicle look for the strategy based diagnostics for the P0300 trouble code they have a step by step process for determining the root cause of this problem. It is basically a trouble tree that works excellent I used it many times when I worked as a GM tech in...

Could be an issue with the speed sensitive steering sensor on the steering column or the variable orfice that controls the amount of pressure coming out of the pump. It could be blocked you may want to try and flush out the system and install a filter inline on the return line.
