Engine idle problem when hot


Recommended Posts

Hiya guys, I'm pretty new to owning a starlet ( ive had it a week) ive got a 1997 ep91. When the car is cold it idles around the 2000 mark which I know is wrong!. Then when the car starts to warm up the revs drop ever so on and when its up to running temperature it starts hunting quite bad. Then last night, it happened I turned the car off went and had dinner then come back outside to start it again and the battery was dead. I jump started it then all the lights where on the dad like I had just turned on the ignition so I turned it off and restarted it, it was hunting then when I went to move it around on my drive I had no throttle and the revs where going down to the point where it was nearly cutting out and it was jerking.



any ideas what I could be before I take it to a specialist?

Idling at 2000 when cold is the wax stat being on. It will idle high to warm engine up quicker then drop to whatever u set idle as when warm - say 800rpm.

Hunting is normally a vacuum leak or dodgy icv. Easy fix with new silicone hoses or cleaning inside - Google clean icv

Did u leave lights on? Running lights at night will reduce battery charge from alternator but not run flat unless the battery or alternator is dodgy. It is possible u have a device leaking electricity. Check fuses. Mine was dome fuse that caused mine to drain overnight.

I'd check all connectors, vacuum, wiring/fuses and earth points.
