They should be CR43TS AC Delco spark plugs. be sure you dd not crack the porcelin when installing them. if you know which one is misfiring take it out and look it over ,for any cracks and ck the gap gap should be .045 the decal under the hood should also have the gap spec.

Spark plug gapfor2006envoy

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.

What is the spark plug gap in a 1991 dodge caravan 2.5 liter useing autolite spark pluges

Throw away the auto liters and get yourself four champion spark plugs. Champions work in chryslers, auto lites/motorcraft work in fords, NGk for Japanese, ac delco for GM's, Bosch for European.

Follow ow those rules and you will likely never have a drivability issue caused buy the wrong spark plug.

Set them to .035" and you should be good to go.

Hello I changed spark plugs and wires on my 95 grand am... I gapped the plugs to .060 and made sure to replace the wires one at a time and put them in the same place... even rechecked the firing order for...

One thing that I have seen many times is people not sticking with AC Delco for this particular application and it will either create a misfire or tell the computer there is a misfire when there is not one. If you used platinum plugs and tried to gap them, it can damage the plugs. I know how hard numbers 1, 3, and 5 can be to change. Are you sure they got in there properly and tight? Start by using the AC Delco plugs and let me know if that made a difference. Also, make sure that the MAP sensor near and in front of the coils is still hooked up. Green 4 pin connector to a black box in front of the coils, attatched to the manifold and just slightly to the left as you are looking at it. It should also have 1 vacuum line going to it. Make sure that the MAF sensor in your air ducting is hooked up. Let me know.

I have a 99 grand am SE 2.4 4 cylinder and my problem #2 misfire, repalced spark plugs with AC delco rapid fires, replaced coil packs, replaced coil pack housing, changed spark plug boots, had ignition...

A misfire doesn't always have to be ignition... it's just the most common cause. Faulty or plugged injector, low compression. You need to check fuel pressure and test the fuel injector flow. Then check compression. If you don't have tools for these tests, take it to someone who does. Testing is much cheaper than throwing parts at the problem.

P0300 - Random / Multiple misfire

The .030 may cause a too rapid burn time condition. And Yeah, .060 is standard GM on almost any make/model nowdays.. It may be one of ur coils.. but that would show an individual cylinder.. Try the .060's and let me know.. esp if it wasnt doing it before
