Engine miss on restart 98 S90
 

Not sure how to explain this but will try. When i start up my S90 to move it out of the garage or way, no problem it starts and runs fine. After shutting it down, and leaving it for a few hours, when I restart the car it misses badly. This only seems to happen when I start the car and shut it down then restart. The longer it sits after the quick start, and shut down the worse it seems to be. I normally have no problem as I usually start the car and drive it, rarly do i start and shut down the car than restart it. When this thing does the restart miss, it sounds very bad and loud, I am worried its a leaking injector and may be washing the cylinder of oil. I almost seems to have a knock while missing???

Any help would be appreciated

Is there a check engine light? Sounds like it could be a bad coil.

Sorry for the delay in getting back, no check engine light, I think the coils are fine. Seems to be more of a fuel problem. Its been cold here, when it warms up I may change the plugs, they have 145000 KM on them, not sure if they have ever been changed. Any suggestions would be appreciated.
