Re: High Idle when car has been running for a while Topic is solved

I checked on the throttle cable early this morning and found that it just broke off by itself. IMG_20200718_162400242.jpg Fortunately, the new throttle cable was in on Thursday. I followed the instruction in YouTube to try to replace the cable. Everything went well except the clips on the cable atta...

Thanks,

Re: High Idle when car has been running for a while Topic is solved

I lubed the cable with 3-in-one oil, more than 3 drops, about 7 drops and hung the cable to the hood for about 30 minutes. Then I stepped on gas pedal a few times to exercise the cable moving in and out. Reconnected it back to throttle pulley and test drove this afternoon. I drove for about 24 miles...

Re: High Idle when car has been running for a while Topic is solved

The spring is inside there. If you turn th...

Re: High Idle when car has been running for a while Topic is solved

The cables do become worn and dry over the years. It could also have stretched somewhat and sticks when warm. You can get special tools to help lube cables. You may also find that: a) There is a broken strand in the cable b) The spring has become weak with age or both. I have never seen a throttle ...

Re: High Idle when car has been running for a while Topic is solved

Early this morning, I adjusted the cable a little bit (when the car was "cold") to close the gap seen between throttle valve spring and stopper. I tested drove the car in the afternoon; whenever, I came to stop in front of traffic light, the rpm dropped below the 850 a bit and went back up to 850. O...

Re: High Idle when car has been running for a while Topic is solved

Test drove the car today and problem still there when car is engine bay was warm/hot. I could see the gap between the throttle spring and the stopper. I shut down the car and removed the throttle cable from the pulley, the gap immediately closed by the throttle plate spring. So the issue most likely...

Re: High Idle when car has been running for a while Topic is solved

This morning, I used my RC helicopter tool - ball link pliers to undo the throttle control linkage (pulley end). IMG_20200711_122147875.jpg Once that end was out, the other linkage end came off easy. IMG_20200711_111752915_HDR.jpg I cleaned up the linkage and the two "balls" on the pulley and thrott...
