Well, yesterday, I did the following...

Cleaned the TB
Cleaned the IAC & IAC passageway
Checked the TPS, was 0.59 volts @ idle and within spec, but I set it lower to 0.56 volts. (Spec is 0.55 +/- 0.05 volts.)
Checked cap/rotor for carbon tracking, found none. (I DID find a chunk missing from my rotor, dammit! I just bought a new one, WTF???)

So the car is still surging when cold. Today, I'm doing an oil change & lube job, I'll see if there are any exhaust leaks, and maybe I'll check the CTS value. I love this Fluke 73 III meter! It has a bargraph at the bottom of the digital display that reacts "instantly", before the meter can lock on to a reading. I was able to "see" my TPS voltage increase smoothly, without the jumpiness of the numerical readout!

 

Mine surges a little to when its cold Tom . I should be checking the same things you are huh ? Does fluke have a website Tom ?

 

Tom,
What is the CTS? What did you do to adjust it?

They must... if you type in "fluke 73 III" at yahoo.com, you'll see the meter I have. I saw it in Sears, too. Funny though how I still like using the Sunpro, probably because I bought it myself.

mvftw, the CTS = Coolant Temp Sensor. As you look at your throttle body, look below & behind it, on the intake manifold. There will be a two-wire sensor sticking up out of the intake manifold; that's the coolant temp sensor. You can't adjust it, but mine might be shot after over 230,000 miles.
