Another way is to physically block off the two normal air sources (main TB and idle air intake hose) and then you can usually hear where the air is getting in. I use a large jar lid to block off the main TB inlet. ----- Original Message ----- From: Larry Alster To: 'Robert McElwee' Cc: 'Bill Cardell' ; 'Miata Power List' Sent: Thursday, July 10, 2008 5:28 PM Subject: RE: strange bipes, ecu, tps, etc problem

Everyone tells me it does work, I see nothing wrong with the theory, but in practice it doesn't work for me. I've tried several times with poor results. I will, however, try it again <G>.

I just took another look at vac tubing including the back of the intake manifold and it looks good. I may plug some ends, put some pressure on it and get out my trusty mustard bottle full of soapy water to see if I can find a leak. I'll check for grounding on the switch. Thanks for the help!

While cold, the idle hunts from 0-2000 RPM. I checked the codes (2 & 17 - NE Signal and O2 not changing) and then cleared them. All vacuum hoses look fine (oops, didn't check on the back of the intake manifold but I'll check later). I bypassed/jumped the bipes CAS connectors, disconnected the TPS connector, jumped GND/TEN, visually inspected and cleaned the CAS connector at the CAS, and played with the idle screw (yeah, I know). The car is still hunting at cold idle. Will try to take another look at it later today.
