Topic: **DODGENITRO**update mech suggest diff.. type of spark plugs?? !!..TRUE OR NO?

[dollicious10]

WOOOweee you guys are brilliant...nice job   thank you guys i was about to have a bird lol   :rofl2:thinking they were messsin with my suv   

I can rest now....y'all so smart!

Ok i have another question:rofl2: :rofl2:try this one out???

So if my km's are at 81..and it's been only 6 days since i took delivery of my new "used" Nitro....is it my job to have the car inspected... say a 120 point inspection to make sure all is ok. My feeling is the dealer should have had all this done for me ...or are they just responsible for the checks when doing the safety and emissions? my maintenance booklet says at 80km's a few checks should be looked at ...etc rotate tires, exhaust and some other stuff....

Then...then also this questions is for an expert in DODGE Cars/engine. Once i'm driving and at a light waiting i can feel my seat and the wheel vibrate a little ..almost like the idle is high ...is this normal for a dodge engine/tranny. It's basically a new truck- 2007... should it not run steady an smooth when stopped at a red light or just in drive mode but not moving.

y'all are awesome get back..i'm a girlie girl so i'm new and i just want to do everything perfect for my new baby !!

or are they just responsible for the checks when doing the safety and emissions?

The dealer is not responsible for any of those "checks".  Essentially, those "checks" are all maintenance items and they are not looked at during the safety.  The safety is actually very basic.

Any used car needs some work immediately upon delivery.  I'd get a transmission service for sure and make sure the oil was just changed.  Coolant change in a year.  The air cleaner and fuel filter are probably original and should be changed.  Since is has a bit of a idle shake a throttle body clean might be in order, but it's pricey for what you get.

Chrysler didn't go broke because they made outstanding vehicles.  If there are no warning lights on the dash I suspect that is the way it's gonna be.

As articsteve pointed out,the dealer is not responsible for any maintenance items on a used car/truck. As for a rough idle,as was said by articsteve as well,Chrysler didn't get in the trouble they are in by making steller vehicles. If you have the 3.7L,its idle is not the smoothest. If you have the 4.0L,they idle very smoothly. At the very least,take it back to the dealer to have them check it out.

Assuming the "dealer" is a Chrysler dealer    Are they losing their store?  Make sure you get in writing on the service work order that you are not paying a cent.  I suspect they will tell you that everything is OK without actually looking at the car.  Essentially you are on your own now.  Locate a trusty independent shop.  I'm sure the car will run for many years.

thanks so much ..any more replys on this topic would be great !!!!

What would be the type of inspection would i ask for to check all is ok with my truck???

thx again

[mrthompson]

I would only tell the mechanic/service advisor what symptoms your truck is exhibiting...nothing else. 

[dollicious10]

good idea arcticsteve and mrthompson will do..

I took truck today to independent mech a good one actually found from my brother..he indicated they place nkg spark plugs instead of acdelco or mastercracft plugs. so that might be the reason wheel vibrates a little when stop at light. nkg are apparently for euro cars...my truck is american. He also suggested platinum plugs more power, last longer and better gas mileage and ...and might stop the shake ..

soooo is all this correct??

[articsteve]

I'd use whatever plug the manual says or the Chrysler dealer uses.

[Squishy]

NGK are Japanese, BOSCH is for Euro cars.  NGK doesn't really have the domestic incompatibilities that BOSCH does, and I often see them in Fords and GMs.

ACDelco is GM, Motorcraft/Autolite is Ford (Mastercraft is Canadian Tire and not a spark plug).  I'm not sure if Chrysler has their own spark plugs.  I've never seen MOPAR spark plugs before, maybe they use Champion or even BOSCH, as they were part of Daimler for a while.

While the NGK should be fine, I would go with what the car came with from the factory.  Replace copper with copper, platinum with platinum, iridium with iridium, etc.  I don't know if the Nitro engine has a waste-spark system - if so, do not put in a single-platinum plug, it must be double platinum.

[dollicious10]

WHAT IS THE DIFFERENCE BETWEEN PLATINUM PLUGS AND REGULAR..WHICH IS BEST FOR QUALITY AND DURABILITY HOTNESS AND MAKES DODGE ENGIN RUN BEST

[Squishy]

"Regular" copper plugs produce the best spark but only last around 30,000-50,000 km.  Platinum or iridium plugs have a much smaller centre electrode giving off a slightly weaker spark, but will give a much longer service life of 100,000-160,000 km.  Single-platinum plugs have only the centre electrode coated in platinum, while double-platinum plugs have both electrodes coated.  A waste-spark system will fire the spark plug backwards every other engine revolution, requiring a double-platinum plug for longevity.

The "best" plugs for your car are whatever it came with from the factory.  It will be listed in the back of your owner's manual.  Those plugs will be the most problem-free, and I would not experiment with non-OEM plugs unless you can afford to replace them again if they do not work out.

I'll disagree because it's not always true.  A regular copper plug may nnot always produce the best spark.  However, Copper IS one of the best conductors of electricity.  There are silver plugs on the market that conduct better, but are $$. 

Also, as far as saying that an iridium plug gives off a "weaker" spark is false.  I think you're confusing it with platimum.  In many forced induction cars (turbo, SC, etc..) the cylinder pressures are high enough to "blow out" a weak spark.  I've experienced this with various copper plugs.  However, once I went to iridium plugs (Denso IK22 or NGK IX Iridium) not only did I make more power, but I was able to increase my gap.  If one can increase the gap, the plug is making a better/larger spark.  FWIW, several OEMs who have boosted engines run Iridium plugs as the OEM plug for this reason.

IMO, the Denso Iridiums are the best on the market, followed by the NGK IX.  On the IS300 and even the POS Echo I noticed superior MPG when running the NGK IX.  I'd say go with those.  The last as long as platinum, but make a better spark.

The only reason I recommend the NGK IX over the Denso is cost.  Densos cost about 2X the NGKs.

[Squishy]

I didn't know there was a difference between platinum and iridium.  Just thought it was two different coatings to get the same long-life plug, and yes, my "weaker spark" comment was based on platinum plugs.  I'll remember that.

Like every Chrysler built engine it came from Mother Mopar with Champion Plugs in it, re-install nothing but the same type of Champion plug or shall the Lord have pity on your budget. Afterall coils and ignition modules aren't THAT expensive

[dollicious10]

well said maritime_s dude thanks i will be sure to let my mech know this declaration!!!

[jamie1]

Many Mopars now come with NGK plugs. The 3.7L in the Nitro is one of those engines.

[dollicious10]

R u sure jamie1 i'm getting dif answers from er one?

Could the tad bit of a shake when stopped related to the spark plugs.... But when i'm driving she runs smooth and sweet . just perfect..2007 fairly new great condition in and out ...only 50 miles on her

what are y'all thoughts or suggestions

R u sure jamie or mr maritime

[Squishy]

Check your owner's manual.  It should list the part number near the back somewhere.

Been working for Chrysler for 21 years. Yes most use a Champion plug, but a few engine are using a NGK plug,and the 3.7L is one of them.
