Well for about the past two weeks I have had trouble starting my car on the first try. I can put the key in and try to start and it may take 10 seconds before the car starts. What I have started to do is give it a short crank and then crank it again and it starts right up. My car has a new battery, fuel pump and filter and I just completed the 60K mile maintenance abour a month ago. The only thing I can think of is the injectors need cleaning or the throttle body. It runs perfectly fine after it starts up, but my fuel mileage sucks. I'm currently getting @ 18mpg in all city driving. Are there any special precautions I should look for when cleaning the throttle body and does an additive like the concentrated Techron really work on injectors?
