My corsa c 2006 1.4 giving an idle problem. I picked it up more when cold the revs will go up to 2k. I did the diagnostics, and the TPS sensor was reset, the MAP sensor was checked, all was replaced

Sounds like there is a vacuum leak somewhere. Snug up the intake manifold bolts, check the throttle body base gasket, and look for bad vacuum lines. Spraying carburetor along the intake gasket, and throttle body gasket works, you would notice a difference in the rpm of the engine.
Tx Rowefast. I will just dbl check the gasket. I've checked all the other scenarios. I even replace the water temp sensor. The last option before I may consider burning(lol), is to re-replace the MAP again. Maybe I can add a bit of gasket sealer?
No, just snug up the intake manifold bolts evenly. You can't do anything with the intake gasket but replace it. Check vacuum line connections, thats were they like to start leaking, the hose gets cracked at the connections.
OK. Checked all the above. Did replace the throttle gasket as well. Yesterday fine. This morning(cold start scenario) it played around(up and down), and then kept at 2000. Gonna replace the MAP sensor again and lets hope for the best. Do you have to adjust the MAP sensor like the TPS with the diagnostics machine?
There is a pipe between the throttle body (bottom) and the air filter housing. Might be broken or slipped off. Check that too. P. S.: I'm aware of the fact that this is an old thread but I'm sure others also checking this out time to time... Look
