too high rpm's at cold start (1987 Esprit HCI)


Recommended Posts

Hi,

My car's engine goes up to 3.000 rpm (instead of about 2.000 rpm normally ) at cold start and it takes about 3 minutes before it goes down to standard speed (about 1.000 rpm.)

As this is obviously bad for the engine I have checked the cold start injector and thermal time switch connections to no avail.

Any ideas ?

Have you set up the fast idle as the Service Notes spell out? (Section LD or LF in the 'Notes)

 

In a nutshell, take a warmed-up, properly running engine. Connect together the two leads on the high temperature switch (two black right-angle connectors next to the Warm Up Regulator). Your engine should RACE because the throttle jack capsule is now engaged.

Adjust the collar on the throttle end of the TJ Capsule to lessen the idle a bit. It is a finicky adjustment...half a mm makes a big change.
