420A Car revs when shifting

[svined]

Hi guys, I have searched the forum for any solution for my issue but cant seem to find what I´m looking for.
I´m from Sweden so please pardon my perhaps bad English.
I recently bought a Eclipse -96, 2.0 non turbo, 420a engine, when I drove it home it acted strange, the rpm went up when I pulled the clutch down for shifting, when I got home I read the fault codes and got 12, 21 and 55.
I ordered and changed the o2 sensor, the map sensor, tps and the iac, after that I disconnected the battery to reset the ecu and went for a test drive, the car doesn´t increase the rpm when clutching, now it dies instead when the clutch is pressed, the same fault codes is back.
Im going to try to calibrate the tps today cause that has not been done, maybe the problem will go away after that.
Any other suggestions?

Have you checked the (Idle control air valve)?

Yes I belive so, it´s the iac you meen right?
I start to think that it might be that the new iac was broken, as I wrote the cars rpm went up with the old iac and down with the new iac, have ordered a new again and will try that.

Hi guys.

I still have the same problem, cant get the codes to go away and have tried with two diffrent iac´s.
Any pointers?

Check to see if your throttle cable is properly adjusted, or stretched/damaged.

Thanks, I will have a look at that.
