Hi!
I have just put in my new restored engine and its a speed denisity system.
When i first started it up i had idle at 700rpm and now suddenly no idle at all and it says code 43,i assume that it says ecm or nock sensor but i dont now where to start the trubbleshooting.
I have newer driven the car yet,just let you now.
Thanks for replay.

 

Ok
I have run the engine for 10 minutes now and the idle are back so thats fixed,but still that code.

 

Still having problem,the car runs best when cold but after about 3 minutes of driving it gets veak and not wery good idle and still code 43.
Thanks for any replays!

 

Your code 43 is for the Electronic Spark Control system. If you do a search of the board you will find where I have posted numerous trouble shooting charts for this code and many others. I bet it also knocks like crazy.

 

Yes you are ded on it knocks badly,can you give me a link of were to start looking,chip,sparkmodule,knocksensor?
Thanks!

 

Ok!
**** happends,i had been switching the nocksensor cable whith the fan temp pigtail.
So every theemes to be ok now,no codes anyway.
Just to let you now.
