4K Random Idle Issue/ Shutting Off While Driving

[ekul]

Hey Guys,

 

I have a issue with my 4k ke70 I'm trying to get sorted asap as i need my car for work.

 

All of a sudden without any reason Ill start the car and it will drive and idle fine, then all of a sudden ill pull up at the lights the second i let the car go back to idle rpm it just dies on me it fires straight back up and runs rough for a while, then ill pull up at the next set of lights and it will be running fine or with a slight miss or it will continually die on me for a while. Ill shut the car off either it will fire up and run and idle no dramas or it will run like crap and start stalling on idle, if i keep the revs up the car doesnt die only on idle but its random when it starts playing up but its usally on 1-2km max. If the car does start up all ok it will either do it first corner i slow down at or the 5th its totally random. I have no idea whats causing it.

 

I had the bonnet popped today just standing there looking at it talking to my mate about ideas and it was running great at the time on idle then it just started to get a little rough all of a sudden and slowley got a bit worse until it was nearly stalling, turned it off fired it back up and ran good again, got down the road and stalled 3rd corner.

 

In the last 3000km its had new leads,plugs,rotor button,dissy cap,and points. Its getting fuel in the fuel filter, got fresh fuel, swapped the coil, checked all the electrical connections in the bay, adjusted the idle. I'm thinking fuel pump or carby?

 

Any help is appreciated sorry for the description been a long day can't think straight haha

Check your timing and points gap.

Adjusted carby, did timing, checked points.

 

Still doing it, one second you runs sweet then it just starts dieing. Where thinking it could be the carby? If theres any head damage or something could it cause it? theres no oil in the coolant or coolant in the oil.

Vacuum leak maybe. I had a small intake manifold leak which caused similar issues.

semi blocked idle jet or fuel cut off solenoid.

[ZacKE70]

have you changed the exhaust system on yours? or is it still a stock exhaust?

Needle and seat checked in the carb? It sounds like it is flooding after a little while, fuel just keeps building up in the bowl until it chokes the motor.

Pulled most of the vaccume lines off today and chucked the ones we didnt need. Did the timing back to 8degrees and mate played around with some thing that goes into the side of the carby thing he disconnected it or something can't remember the name of it. Drove it around for a bit running sweet then died in the ass again. Hopefully check it out tomorrow again. WIll post up when i work it out, I'm guessing the next thing will be looking into the jets next
