Civic 2003 ex P0505 and P1129 I put it all in this video [autostream]http://autostream.com/ibcivicforums/?page_type=firebirdplayerthumbnail&framepage=1388& transactionid=1363372639-7611018765&posted_by=_www.civicforums.com&youtube_ video_id=WE3A9KkBBU8[/autostream]
I replaced and put in new:
Map Sensor
IAC Valve
TDC or Crank sensor
All Plugs
Valve Cover (Just needed to do)
Valve Cover Gasket (Just needed to do)
Oil pan Gasket (Just needed to do)
Car idles extremely low and even stalls. When driving will get to 3000 RPM before shiftinf once in second you must let off and let it shift or will just rev rpms to 3500+ RPMS and not shift. Car also shakes while waiting at light.
I am open to all suggestions. You can see what I have already done. Check the vid, maybe you will see something I missed.
Thank you in advance

If you think a good mechanic is expensive, try hiring a bad one

What is that wire connector (looks like it has 3 wires) unplugged laying right behind the IAC valve? Maybe that's why it doesn't idle right?
MAP sensor good?
Wiring for MAP also good?
All connections secure and seated at the PCM, and the harness connectors in front of the PCM? (IAC and MAP wiring both are contained in PCM connector "A").
Clear codes. Does that code return immediately? How long does it take to return?
Next steps might be some actual voltage checks and/or using a scanner to read live running data from the PCM.
The P0505 just means the PCM couldn't attain the idle speed that it wanted. It doesn't have control of the idle speed, so it set that code.
