Hey all, my car has had a bit of a miss at idle for a while but I didn't think much of it and figured I'd sort it out when it got worse. Well, it got worse and now it sometimes dies at idle, so the choke has been used to keep her happy. Misses severly at idle and sometimes when accelerating it'll miss causing some harsh surges. When highbeams are put on the idle speed drops and the misses are more frequent.

 

I jumped it to my olds landcruiser to see if it was a weak battery and it wasn't, could be connections though possibly I guess. Leads & Plugs are fine, so I figure it must be the contact breaker points or coil?

 

Is my reasoning right? Or any other possibilities?

 

Any tips on how to determine what it is? If its the points, how hard are they to change, is it doable without taking the dizzy off the engine?

 

 

Btw its a KE70 with stock 4k.

 

Thanks

don't remove the dizzy. just take the cap off

 

you really need to hook your car up to a tune-up machine. i suggest you go see a mechanic

Nah, can't afford to and I'd rather give it a bash myself. I'll change the points anyway and see whats next...

have you checked all the obvious like spark plugs, ignition leads ect

its not that expensive, probably about $30 :dance:

Leads & Plugs are fine

 

 

And the timing should be sweet cause I did it about 3 weeks ago and can't see why it should have changed.

hmm... if thats the case...

 

What exactally do you mean by a 'tune-up machine' :dance:

 

A diagnostic machine of a sort and tells you your state of tune?

did you tighten the dizzy up. check it again just to make sure.

check fuel mixture and check for air leaks.

hard to explain.

 

if you get it done the mechanic will show you.

turns out it was in fact points, cleaned up the current pitted ones and runs a treat now. Will put new'uns in tomorrow.

 

$120 for a timing light tho!? wtf! It did have a dwellmeter and tacho as well, but stilll! :dance:

Umm, all i know for sure is my ke70 has the same problem, i live with it, but i think its running excessively rich, so i think i mite muck around with the idle mix screw soon, but yeah, can't think of anything else

 

cheers

 

Ed :P

sorry read that a bit too late, what is the "points" as such and how do u clean them without breaking anything?

 

Cheers

Points are inside the distributer if you run the standard K motor dizzy. My car has the same problem at the moment but this time I'm going to fix it once and for all by putting in an electronic dizzy..

I had exactly the same problem, was a faulty plug! :lock_folder:
