Verify spark and fuel at cylinder 2. That's the front left cylinder.

Thanks Cougar: it turned out that the plugs were firing allright except #2 and it throwing the 302 code. changed out to DBl plat champions.. it went away and still has a slight hesitation but i can live with that until i replace the Ignition coil... thanks ken

 

Have the wires been replaced yet? If not, you might consider replacing them before hanging on a coil. It's a fairly common thing to see the coil go south on these vans but IMO, old wires would be replaced first when trying to fix a slight misfire.

 

+1 on checking wires... I use iridium plugs, and run them 100,000 miles, and when I change them I change the wires too. In the last 605,000km my 2007 has gone through 2 (or maybe 3?) coil packs.

 

Just an FYI and not a recommendation but at 212K miles and 18 years later my plug wires are still original and she's running great.

 

That may be the case, but you have a different generation caravan and engine.
On this particular generation, the wires tend to rub a little (against each other, and the brake booster hose etc) creating wear. trust me, after 15 years and millions of miles in the taxi industry, I have seen many caravan plug wires go bad, often resulting in something that feels like transmission shudder, but isn't. Many people mistake it for tranny issues.

 

Sounds like you have a VERY unusual perspective there, Jordon. Most of the amature DIY guys here like me only have the one van that we drive and work on. And even the pros who make repairs every day don't get to drive and monitor those same vehicle afterwards.
So feel free to share your accumulated knowledge base here as much as you like!

 

Hmm. Guess things went downhill after the 3rd gens. BTW. Chaffing is easily detectable. Crank it up and open the hood on a dark night. If you see arching it's time for new wires. No arching even after spraying down with a water mist? Save your bucks.
