Installed the new TPS and it did not help. Now the RPM will shoot up anywhere from 1400-1800 and hold until I come to a complete stop. What else can I check? The one thing that I am uneasy about is the AZ Spectre cai the PO installed. It just bothers me, and does a lot of whistling when I accelerate. There has to be a way to trace this down without having to keep throwing money at it.
If a visual inspection does not reveal anything use a 3 ft or so length of fuel line attached to propane torch (unlit of course) to direct a flow of propane at various segments of the intake plumbing--if the engine speed increases (or even stabilises) then the propane flow is hear the leak.
Some people use TB cleaner or other flammable liquid sprays, however this is a long way from the safest way to check as the aerosol liquid can puddle up and create a fire. The propane dissipates quickly in air and is far safer.
