I put new ICV, TPS (adjusted correctly), AFM, plugs, etc. Changed one bent ignition wire, all of the are now ok. All electrical stuff seems to be right. No vacuum leaks found. Fuel pump new, FPR running right.
So this is the case:
-when starting at cold, engine revs to about 950rpm (high idle, maybe it should be a little bit higher). No vibrations from the engine could be traced.
-when the engine is fully warmed up, it starts to shake, idling at about 700rpm (they should be 800+-50). It only seems to do this when idling. You can see the engine vibrating very fast with hood open. If you put the foot on the gas vibration dissapears.
-if when warm, I turn it off and then, 5 minutes later, I start it again, it goes down idling at 650rpm aprox and vibrating more. After some time idling (30-60 seconds aprox) or if I start driving it, idle returns to 700rpm.
-if when warm , I turn it off and then, 50min later (temp gauge showing a bit off the blue zone, so its not cold but not fully warmed up either) I start it again, idle goes to 750, bounces to 650 softly, then again to 750, again to 650 and finally stabilizes at 700.
Could it be a lean running condition? So when it's cold mixture is right (and it should be a bit overfuelled), when warming up a little lean and therefore idle bounces some times before stabilizing, and when fully warm its too lean that cause a rough running? It's the only thing I can think of, but don't know why
