Sticking Throttle
 

My ZT190 5-speed manual has been running very well mechanically.
I have had a couple of episodes of the throttle sticking on. After getting up to speed, 4000-ish RPM and going to shift to the next higher gear the revs continue to climb with my foot off the throttle. The pedal returns by itself. trying to pull it up with my toes shows it's already back up.
When I allow the car to slow down in gear the revs decrease and don't go back up when the clutch is depressed.
Opening the bonnet and operating the throttle at the throttle body manually there are no sticking issues making me think the cable is the culprit.
Any other possibilities?
As the LHD cable is relatively cheap I have ordered one but that will take a couple of weeks to arrive so thought I would ask. :)
The car has 125,000km (80,000-ish miles) on it.
Any point removing the TB end of the cable and squirting lubricant down it? With my MGF that only made the problem worse. :shrug:

How’s the weather? This is a known issue with the throttle body when the temperature drops to freezing.

Had the sticky cable/frozen butterfly on mine (at minus 25c), have used a marine white oil on my cable and throttle body, suspending the cable while exercising it a bit - seemed to help, but a clean throttle housing/cleaned breather system probably helped more. I’ve seen a few homemade re-routing jobs on the air intake, moving it to nearer the exhaust. But I understand from your previous post that it doesn’t get that cold in Vancouver.

Good luck with the new cable, and with Meghan & Co.

Thanks for the info!
Normally I would say that the weather here doesn't get very cold, but in the last few days it has dipped to well below zero C. for the first time in two years.
Things should be better in a week or two. I'm sure that by the time Harry gets here things will be sunny!
Like most Canucks I don't have any issues with Megxit landing in our back yard (Well, 50 miles away or so apparently) but the usual media hacks and left-wing whiners are starting to whinge about our government paying their security costs. With the amount of money the government blatantly wastes the 2 million or so to supply security would be a drop in the bucket compared to the benifits they will bring in tourism alone. If they keep living near Victoria (which thrives on being British-ish) droves of rich American tourists will descend on the place to try and catch a glimpse of them, or buy a Harry and Meghan teacup or two. Regardless, the two of them support some good causes and I have a respect for Harry serving in Afghanistan when he could have been sunning himself on a frigate somewhere safe.

Back to the ZT...I have given the TB linkage a good spray with Tri-flow and am hoping that the problem will stay away until the warm weather returns.

“Landing in our back yard” would seem a most apt phrase.

“Sunning himself on a frigate” - good luck, served on two, daylight was unknown, and going topside usually meant the aerials needed repairing - often in gale force winds.

Don’t know your Tri-flow, I used an oil called Tetra Sea (American product) - figured it would repel moisture.

You can tell I was in the Infantry-bitter and jealous!:D

Tri-flow is also American made. It's an excellent lubricant that leaves a bit of teflon behind once the solvent component evaporates.

Try being a Submariner :p:

Not that brave mate!:bowdown:

I like my daylight.

Too fond of soap & water to qualify ... first ship was HMS Forth with A class boats alongside in Singapore ...

S and T boats so no worries about fresh water :p: Our only limitation was the amount of food we could carry. Managed 9 1/2 months dived in my last year on Trafalgar.




Only two types of naval vessels ... Submarines and targets ;)
