I've seen most of the links to the T.E.C. procedure but just want to clarify a few things....How much of the AC Delco TEC needs to go into each cylinder? I've seen quantities from 10 oz of the liquid in each cylinder to a few squirts of the foaming cleaner? And now that I mention it....Should I go with the Liquid? Or the foaming spray?
Also, I know I have to drain the oil and replace the filter after the soak, but do I need to do another short oil change after that? Or can I just do a regular oil change and run it for the 4000 mile interval? Thanks all for any info.
P.S. Envoy still running sweet after the PCM was finally diagnosed and replaced!
