Hyundai 25L-7A:
Diagnostic tools

Hello Everyone. My 25L-7A tends to run fine when I start it in the morning. After it gets good and warm it will stumble like it is going to stall but never dies. It may run rough for a minute or so then will clear up and run smooth. After the engine is warm and it has sat some time it will not start again. Almost like a vapor lock. I just intalled a new regulator and no change. I am going to try a new mixer valve. It has new spark plugs and coils. I have been searching for a diagnostic tool. Are these available?

I know this is a little late lol but as far as diagnostic you will need the psi software AND a special code to hookup to the vehicle nodes. You will also need troubleshooting manuals, which can only be accessed through Hyundai Construction Dealer Portal. So unfortunately you will probably have to get your local Hyundai Forklift Dealer to come look at it, if you still have it lol

Fact of the week
Belgian bar owners complain that tens of thousands of their stylish beer glasses are stolen by souvenir hunters every year. One popular bar requires patrons to hand over one of their shoes as a deposit. The shoe is put in a basket and hung from the ceiling until the glass is returned after the beer is consumed.
