geo prizm 97 1.6L spark plug gaps

[sunyvel]

Hi, I recently decided to change the spark plugs of my 1997 Geo Prizm 1.6L. I noticed that the spark plug gap setting was given as 0.031 in the haynes manual. But in all automobile shops, I noticed that they specify 0.042. I am a bit confused as to which is the correct setting. I currently have 2 sparkplugs set at 0.042 and other two at 0.032.
Is it an error in the manual or is it an error in the other database.

I dont own one to be certain. however I do own 2 japanese cars of similar years...

In this case, if I had to assume someone was wrong.... Id assume billy bob at that auto parts store doesnt know.

i had the parts store tell me the same thing about my plug gap he said that it was the( 0.042) and i dont have a book on the car so i took his word on them but then when i pulled the old plugs out the reading on them was( 0.031)around about give or take but i left them at( 0.042)and the car run okay so i dont know but if you find out something please let me know.

the only thing that i notice is that on take off it has a low respons. with the gap set at the 0.042.( but thats what i think.
