If I buy only ECU from the same model will it work? Do I have to buy ignition key barrel ?

 

At lest in the states you can just swap out the computer from any the RD or Elantra from the same generation. 1996-2001.

 

That's what I thought , but wanted to be sure

 

You can test the spark plug leads with a volt meter/resistance. Check to see if they are within spec or have any cracks in them.

 

Checked the old ones and they were within specs, but still bought new ones.



The ignition system is brand new ! Plugs, leads and coil pack.

 

Blow it up yet?

 

I have a beutiful girl to blow it



We were on vacation , but before that I was at the petrol station and met a friend of mine. He had rd2 before and told me that he had the same problem... exactly the same ?! I was WTF... really ??? So his solution was Bardahl 6 in 1 injector cleaner! Again WTF !? He was so sure, he said just try it you will see!



Bought one and did everything that was written on the bottle. Early In the morning we were on our way. After 50km or so I was at 5th gear and when I tried to accelerate the misfiring was there again. All the way to our destination we had this f*cking issue and it was getting worse !!! Got there and left the car. Didn't need it for the whole vacation so I started it today and same sh*t.



The problem is getting really BAD! Low RPMs , high RPMs doesn't matter anymore! Almost everytime I press the throttle a little more BAM misfiring, banging, poping...

 

not sure if it's been mentioned or you've already checked but could it be the ignition amplifies in the ecu? we've had a few rd's go down with misfires in the UK and the result has been burned out amplifiers in the ecu. These can be de-soldered and replaced for new ones, if i can find the thread on the uk forum i'll post a link

 

What's one of the reasons we told him to swap out the ECU.

 

Ok guys I will buy ECU tomorrow and will swap it this weekend. You might be right, cause I can't see anything else that can cause this problem!



Again... new plugs, leads, coils ! New crank sensor, fuel pump... tried another TPS and another set of injectors !
