New to the forum, and after a little advice over some niggles I'm trying to get to the bottom of. My MK2 is running the 2.0 abf with the factory abf management. I did the conversion around 10 years ago. I have had an issue over the last few years where by when I start the car it runs really rough, and will not clear. The only way to sort this is to turn the car off and restart, it will then run fine after that until the next day. Another issue I have which I think is the ignition switch, is when turning the key it's not always starting and I just get a click. Not sure if this could be related to the other issue? Any suggestions greatly appreciated.
could be temp sensor. mine started doing similar, mostly ok but some days it had no power and would stall. rebooting the engine fixed it till the next time. got worse and worse over time till eventually it would struggle to start and happen pretty much every trip but before you spend money get the faults checked, when you know its going to run rough plug it in and check thru all ecu measuring blocks see if any sensor is returning weird values
