Ok, I have a question about it.
All other sensors checked good as I have posted in my MAT thread.
Replaced:
MAT sensor
New o2 sensor
MAP checks out ok
No sign of exhaust leaks
TPS checks ot ok ...vehicle shifts fine....
IAC was tested with a IAC tester and showed to work. But would not bring it down to correct idlling rpms once it was run up to higher rpms.
I read somewheres on here that if you put something (plastic card or similar) on top of the IAC port on the TB to stop the air ... the engine should die. Mine keeps running.....
Or should I put the top back on the TB with it pluged up and test it that way.
There is no vacuum at that port( with the top air box still off). Does that signify the IAC is bad?(not allowing air in)...or the wireing is corrupt( if that be the case)? Remember I did a smoke test on the vacuum system ( mentioned in my other thread), so no leaks showed up in the vac system.
The idle is fine at start-up then it starts searching from 750- 1000 rpms then gradually goes up to 1250-1500 rpm once warm.
