1991 Chevy S-10 sparkplug Gap?

rdhack · 08-12-2008, 04:34 PM

Does anyone know the correct Gap for a 1991 Chevy T-10 Blazer 4.3L.

I just noticed that the radiator shroud sticker that I went by is from a 1993 Model- It said .045 Inch. My 1991 much have been wrecked and replaced with it.

Is there any difference between the 1991 & the 1993 engine as far as the plug gap is concerned? I do have a very slight hesitation upon acceleration.

Thanks

I am going to have to agree.... there were no changes in the motor design until mid 1995 when they were produced as vortecs... so I would think the gap would be the same....

How long has the hesitation been there? Perhaps it is something else we could help with.....
