The same problem is still occuring.
the car will not run/idle for more than a second or so.

engine running (throttle proped a little open to keep it that way) i got around 2v. B to A ive got 4.8v. Does this tell me my sensor/wiring are deffinately o.k.?

valves are properly adjusted

map sensor/pigtail have been replaced with no change.

IAC passages were cleaned

how can i figure this out without scan tools? im pretty tired of throwing money at this car without results.are there any other sensors that might confuse the MAP's readings?maybe a bad throttle body?
