My 91 Z28 LB9 305 5-spd has developed a terrible stalling problem to the point of being undriveable. It starts fine and runs OK while cold, but after driving for a while, it stalls any time I need to stop. So I have been scanning the boards and this weekend my plan is:

1) Check base timing
2) IAC cleaning
3) Check TPS
4) Check PCV
5) Check for vaccum leak

If these don't fix it I'll need to look elsewhere.

I have two questions:
1) The tech article on IAC cleaning says to jump the A & B ALDL connectors with a paper clip, well I just bought a Sunpro scanner from JEGS:
http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=3304&prmenbr=361

If the scanner is set to engine mode, wouldn't it do the same thing as the paper clip? I'm assuming that the paper clip puts the car in diagnostic mode, right? I just got the scanner yesterday and have never used one. Has anyone used this one?

For the TPS, I have a Fluke voltmeter that was given to me for helping someone move, but I have never used one. It didn't come with any jumper wires, just probles with allegator clips and pulling those off displays the probes. Can I just probe the TPS from the back or do I have to make jumper wires? What's the best may to make jumper wires? One more question: the voltmeter should be set to vdc (volts dc right?)

Any insight would be great.

Thanks
