When I start my car in the morning it idles REALLY rough. Actually anytime I start my car when it has been sitting for a while. Even in the day time. Like I am pretty sure it is missing on the idle. It has new plugs, is it just a normal thing for an older motor?

Thanks...

 

I have this problem as as well. If the car sits for more than 6hrs or so, I can't start the car and drive right away. All of the time I have to let the car warm up about 10mins before driving. It's a new motor!

 

Anyone???

 

check timing??

 

Pull one plug wire at the head and see if the idle gets worse or stays the same, put it back on and pull the next one and let us know what happens. Next spray some carb cleaner into the air filter box and see if the engine runs better, spray some around the intake to head gasket area and see if it gets better, let us know please.

 

It's the FITV in your throttle body, just get a new throttle body or an aftermarket one will remove that completely. I'm selling one for a B series if interested.
