m30 idle problem ?? help

[blingsta]

Guys, i was led to believe that the ecu and tps i had running my 3.5 were actually from a 2.5.. so i got hold of a 3.5 ecu and tps.. bolted them on and adjusted tps.. car now idles fine, but as soon as i drive away and in between gear changes if i leave my foot on the clutch for long inuff, the revs stay at 1500 rpm's, if i stop at lights, it takes about 10secs for it to drop down to normal.. why is this?

Sticky tps.

Possible afm missmatch too.

Does it go better btw ??

[blingsta]

no difference fella.. but benefit of the doubt, its not set up properly!! as for the AFM, its only the 3.5 ones that are upside down anyway, so dont think theres any issues there!.. TPS seems clean and clicks away without issues

Ecu still learning or a small air leak is possible too.
