Spark Plug Gap!

[Fireplug]

If its running good leave it alone.
If it aint broke dont fix it.

Yes, they are not supposed to be gapped at 0.045.

Plats are supposed to be gapped at 0.060.

If you want problems, install Bosch plats in a 4.3L.

Spit and sputtering mess with those.

i'm runny bosch plats and my jimmy also hesitates on take off you think this is the reason?

[BlazerLT]

Yip, Bosch plats are junk in a 4.3L and cause lots of problems.

Just go with a standard AC Delco plug and you will be VERY happy.

[Fireplug]

I never use any ign system part unless its an AC Delco part.
Have see way to many drivabilty problems because of non Delco parts

[BlazerLT]

That is very true.

They are made for our truck.

[atomicpulse]

well I switched the gap to 0.060, still idles normal, feels like there is a little more power now.. could all be in my head, gas milage seems to be the same as well

[BlazerLT]

Did you reset the computer by pulling the negative terminal for 2 minutes?

[atomicpulse]

yes, i actually had the battery out for a while it was in the way of some work i was doing

[movin2stereo]

Are the Bosch +4s junk?

[chcknugget]

I've heard that the platinum plugs can be damaged by gapping them. Is this true of the delco plat plugs? I just don't want to hurt my plats

[BlazerLT]

All Bosch Plats are junk, don't use them.

The AC Delco plats can be gapped if not properly gapped from the package.

[chcknugget]

Yeah I already got the delco plat plugs. They were $5.39 each so I don't want to hurt them.

[BlazerLT]

should have go them off of ebay.

Got 8 for 20 bucks.
