Georgio Posted April 11, 2012 Share Posted April 11, 2012 If it starts fine when warm,but difficult when cold,it could be the coolant sensor.This informs the ECU if the engine is cold and enrichens mixture.It is in the back of the engine,on the inlet manifold,between runners 3 and 4.It is a bit awkward place.Try to unplug it and start the engine.From what you describe,it seems like the ECU doesn't enrich the mixture to warm the engine faster.It's like running a cold carbureted engine,with the chock off.

Disconnect the sensor and try when the engine is cold.If it starts and idles better than with the sensor connected,then chances are that the sensor is not working as it should.If I understand correct,you said that when the engine is warm,and you try to start it,it starts and idles fine.Am I correct?

Georgio Posted April 12, 2012 Share Posted April 12, 2012 (edited) Yeap...that's the one...you must pull it firmly,since this has a safety lug.But not from the wire,pull the connector.It feels like it is gonna come off,but it doesn't!Take care of your hand,when it comes off,you can hurt it on the firewall,bolts in the surround area....well,I did.lol.
