We switched out my spark plugs around 1am last night, then put everything together and called it a night. This morning when i fired it up, the car sounded loud and slow. Misfire I assume? When we made a 2am walmart run, the ONLY fitting spark plugs wal mart had were 2 copper and 2 platinum...was it possible that's what caused the bad idle? Also, when placing the spark plugs in, do they snap or pop in? maybe only 2 are in correctly? I'm not sure, but it doesn't sound good.

Any suggestions?

Did i void the powertrain warranty by switching plugs?

did you check the gap on the new spark plug.. i dont trust the manufacturers stock gap..also did you make sure you lined up the same ignition coil for each plug..

how big do you recommend the gap should be? i pulled the ones i bought straight from package and put them in without tampering. Gonna go to auto zone and buy a full set of iridiums after work today and try this again.

i want the same plugs, but new. hoping auto zone carries them. i think 3924 was the fitment. when i went to get plugs i had to look it up in a phone book of spark plug sizes.

vibrox do you really expect the op who is from Arkansas to understand your post? and do you think he would resort to looking for online sex shows on a Yaris forum?

He must have something else in mind regarding a gap-tool and the need for shows of that sort. :iono:
