Or starting fluid. Spray around the intake and plenum, if the rpm spikes (do with engine running), you have a leak.

As always, thats your option. I just like it better than spraying all kinds of fluid onto my engine.

ah my car runs alright , its just a hard start and it idles higher then it used to.
when i first bought the car it started first crank no problem, idle was at 750 , one day i pulled a plug to check it, put everything back on and now it idles between 1250 and 1500 and its a rough idle
