Default Rough idle when warming up.
I usually have a very rough idle when warming up especially when the temp is below 50F. The other day I was backing out of the driveway and I thought the car was going "konk" out. I have 50K miles and the car is an 02.

Do I need a tune-up? I dont know when they did it last.

Thanks,
Drew

Default Cold start injector. If it starts up right away, and then runs rough, the cs isn't shutting off.
If it cranks too long b4 starting, cs isn't coming on. MAF can be bad too.
