Hi, I have a 83 XX KE70 With a 4KC in it. It has the stock carby on it and only 143000kms.

 

It has a horrible miss while cruising at around 3000rpm, no other revs just around 3 grand. Its the only issue i have with the car. Doesn't hesitate on take off and idles fine.

 

I put a carby kit through it and it hasn't changed anything, could it be my coil or timing?

 

Cheers

Timing should be fine.

 

Coil should be fine. If the coil is playing up, the car stops.

 

Check leads and plugs. Used to have a similar problem when I ran Bosch plugs. Ngk's were fine, Bosch used to crap out the plugs. Go figure. *shrug*

 

Start the car in the dark with the bonnet open, and see if you can see the plugs leads arcing. They're/ it's buggered if they are. May only be one plug lead playing up.

 

May be dizzy, but I can't see why.

 

 

Cheers forgot to add that Ive got new plug leads and it has Bosch plugs, ill swap em to Ngk and see how it goes.

Check the dizzy shaft for side play and also that you vacuum advance unit is working. Cheers.

p.s. It could be a broken discombobulator spring, but I doubt it.

I will do that today as well.

 

IT shouldn't be the discombobulator spring the guy I bought it off had just replaced it before I bought it off him
