Car's having prob since spark plug changed
 

I changed my spark plugs a few weeks ago and now have a little problem. Sometimes, the car doesn't start: when I turn the key, the rpm goes to about 900 rpm (as usually) for maybe half a second and then immediatly drops to zero and the car stops. It takes only a second for this to happen and don't know waht's wrong. If a give a little gas at starting, it will start alright but once in a while, the car doesn't start. It's my first time I changed my spark plugs but everything went find so I don't know what the problem is...could it be the spark plugs' gap? If the gap isn't good, would it create this problem? Any input would be appreciated.

hope there ngk platinums :nod:

I second that. I had a slight problem similier to that before going back to NGK Platinums....

Hmm if your RPMS are jumping sporadically from say 1000, back to 0 then it suggests that your throttle body need cleaning, my cars RPMS would jump to 1500, then to 0, then back to 1500, and once I had the throttle body cleaned out it stopped so check that out.

Thx for the replies and yes I'm using ngk platinum plugs. Today I tried to fix the gap and now I hope the car's gonna be fine.
And Harrish, I'm not sure if my case is the same as yours, for me, it's only at the starting like usually when I start the car, for a fraction of a second, the rpm goes to 900 and that's a normal thing, but it's only right after the 900, the car stops. Like I said I just changed the gap so I'll see what it will do.
