They should be pre-gapped, but you should always check in case someone dropped the box.
The gap is .060

This actually depends on what plug you are using. A platnium plug should gap at .060" while the conventional plug is gapped at .045". The AC delco 41-392 gaps at .060" while the AC delco rapid fire gaps at .045"
. I would recomend the 41-392 and gap it at .060" however there is some desperity in the manual and labels on this matter as platnium plugs were a newly offered back in that day.

The above information is correct but techbuster, there was no 2.5 in a jimmy. Especially not for the 1999 GMC 4.3 liter engine, as stated above. The only other option for those style trucks in that year was the 2.2.

It would give the plug gap on the Vehicle Emission Control Information label (VECI label) that is pasted to the radiator support or under the hood. A long white sticker label, with emissions information for that particular vehicle. The spark plug gap is always listed there.

Are ACDelco 41-942 Spark Plugs the proper plugs for the 1996 GMC JIMMY 4WD V6 , are they pre gaped and what should the proper gap be?

they should be the 41-932 plugs. AC Delco
gap should be 0.060 inch.
Check the gap before installing any plug. You never know if they were damaged in shipping before the part store got them, or if some idiot employee at the store attempted to juggle them while bored one day and damaged them by dropping them.

Idels high and cuts out

The 4.3L V6 is known for idling high when the car has around 100,000 miles more or less. The cutting out could be a fuel filter or fouled/dirty spark plugs but more likely bad spark plug wires. Replacing them all should only run about $80 if you perform the work. Just make sure you get AC Delco spark plugs with a decent set of aftermarket plug wires and do those one at a time so they stay in the same order to avoid misfire/hesitation issues.

Spark Plugs Manufacturer Specs

AC Delco is the only plugs I will sell to anyone with a newer style GM of any kind. I have sold "other" brands of plugs for them, but the customer always comes back complaining. I don't know why, but anything else will cause a miss. You can go ahaead and run something else if you really want to- but I warned you no matter what anyone else says.

@Gap .045" This is a Platinum High Performance Spark PLug

Option : ASP AR25
@Gap .045"@ High Performance

Stay away from those Gimmick Spark Plugs , they are just more money for nothing. A good platinum spark plug is all you need, the key is to gap it correctly to your application...

On GM products Vin # W it is .045 plug gap
On Gm products Vin # Z it is .035 plug gap

You will not have huge gains in fuel mileage from replacing spark plugs except to say that if your old ones are just extremely bad, there is no magical spark plug with extra mileage manufactured into it.... Hope this helps...
