Yes Get the right key at a GM dealer, take along the car serial number because there are several chip options and they will have to look it up with serial number

These vehicles are common for leaking fuel injectors. I would do an injector drop or balance test.

About an hour, Open the lid where you put the fuel, there are four screws that you have to remove, remove the lid, pull the rubber boot out and there is the pump sending unit. remove the eight or ten bolts and pull the unit out. replace the pump and install in reverse order. These are the easiest ones I have done. You can do it.

have you checked the EGR Valve for leakage? if it is leaking the valve will get very hot at idle right away after a cold start, also the intake manifold gaskets leak on these, it can leak under the manifold and on the top do a propane enrichment to see if engine smooths out at idle. I will bet the EGR or the intake gaskets are the problem, u also never mentioned the all important electronic engine control fault code test, go to the link for instructions on how to do this test without a scanner.

I have upgraded or retrofitted older cars with r134a before with the ester oil and never had any problems with the refrigerant working with the old oil, as long as you put a few ounces of the new oil in.

The kit for r134a conversion from R-12 has everything you need to upgrade without removing all of the old oil.

Of course, in the early days of r134a conversion in the early 1990s there were people who recommended that you take the whole system apart, compressor, piping, receiver drier, etc. and replace the receiver drier and dump out the old oil.

In my opinion, this is a very expensive proposition, and good to excellent air conditioning can be had by following the R134a conversion kit instructions and installing 2 or 3 cans of refrigerant into your system.

This can be done by yourself.

Watch, if you're in California, you have to return empty cans of R134a to the store because they say that it is harmful to the environment and they want to keep track of it.

Good luck staying cool with R134a.
