New here and wondering if any of you have any experience with this problem.
my car was running fine a couple of weeks ago. it had been 6K miles since its last service so i thought i would give an oil change to try and keep things fresh. I also decided to put 4 new spark plugs in it as well as i dont know when they were last done. everything went smoothly, i got the car home and that was that. However, when i jumped back into my car to start it, it turned over for ages before it eventually fired up.
Been having this problem now ever since that day!!
its starts fine first thing when the engine is cold but when it heats up to running temp. its a nightmare to start again if i turn it off. When it does start there is also black smoke coming from the exhaust and it tends to splutter a bit as well!!
any help much appreciated guys!
