Hello , i have a lexus ls400 1990 and it has a starting issue. it start but shuts off and i have to give it a little gas for a couple seconds and then it will idle but rough, once its been running for 10 mins i can turn it off and turn on with no problem. only at cold start it happens. what do you think it might be?
Try my video. Make your car run better with a little spray cleaner. It's on YouTube. Pray it's that and not something more complex like a worn out of fuel pump or fuel injectors that need replacing
