HELP!! ECM Trouble codes

[black_rob00]

I went to Auto Zone and had a diagnostic done. This is what I got:

P0140: 02 sensor circuit no activity detected (bank 1 sensor 2)????

P0113: Intake air temperature circuit high input

P0300: Random/Multiple cylinder misfire detected

P0507: Idle control system RPM higher than expected

P0401: Exhaust gas recirculation flow insufficient (I know about this one)


Which 02 sensor??? The first or the second one??? I fixed the Intake air temperture circuit. It was cut. That took care of the random/multiple misfires. Can someone help me with the others??

i have the 0401 code right now...basically if you welded your bung shut youll get that code..read the thread i started in the F/I section with the title as that code and see what toronto suggested...im going to attempt it tonight or tommorrow.

since the egr has something to do with idle, that could cause your 0507 code i would imagine...

0300 - check your spark plugs for proper seating, wiring for proper wiring and plugs for proper gap i would say...unless bad gas could cause this which i doubt.

0113 - did you drill a hole in your filter for the air intake plug?

0140 - are both your o2 sensors hooked up? are the wires melted?
