I'm currently experiencing a BAD putt-putt-putt sound from my exhaust. I've already replaced MAF and O2 sensor. I'll be putting a new Greddy SP exhaust on next week, and a new Warpspeed Y pipe and high flow cat next month. Exhaust needs to be replaced anyways because of holes, but is this a likely source of the problem or is bad spark plugs more likely? I put on Bosch 2 platinums a couple years back (before I knew better), as well as Bosch premium wires, cap and rotor. If group consensus is to replace plugs, which ones? I know NGK is the brand I need, but there are many variables... normal temperature, high temperature, V Power, another style(don't know what they're called but they have a needle sized contact), etc. I appreciate the insight of you all. Thanks!

Con sensus yess, but individual decision depending how u like & use u max...

I like the REAL conducting copper WIRES witk 1k resistors, NGK platinums = less work, runs best. NOPutputt...

Btw. Your cap may also be leaking...

Ok, I spent the $10 and replaced spark plugs this afternoon with NGK V Power plugs. No change, still get the rough putt-putt-putt. I pulled neg terminal on battery while doing this so computer would have fresh reset. Now what? I've read posts where people say spray laquer on the cap. Inside/outside/both sides? I appreciate the help.

check the cap and rotor for wear and cracks


check the resistance of your wires.

the V power plugs are very good, im actually going through the same problems and so far my putt putt hasnt gone away. im changing the cap soon and also getting an exhaust, but i really think its the muffler.

This may be a injector issue..

maximagxe90

i think it is a fuel injector for the vg engine,

because my car use to putt putt before my fuel injector was change and no more putt putt after the fuel injector was replaced so no more putt putt from the tail pipe,

a muffler is not going to fix the putt putt thing either

my friends VG does that aswell, not really sure what is causing it

my VE had the same issues, and injector replacement fixed em

TommyT

Mmmmm, sounds expensive. That might need to wait a while. Guess I'll get my book out and see if its something I dare tackle myself. Exhaust comes first though.

Wiking

This is dirt CHEAP, do all these before anythin else:

All sides that it may leak = both sides. There may be cracks through it or only one side. Tape on 'electrodes' first...

...and DIY THE WIRES. Next DO the distr & other grounding wires, check voltage levels: http://www.cardomain.com/ride/748507/10

If it shows to be an injector issue, do what I did before doing anything else:

Get some X1-R and run at least 3 tanks. That solved my injector problem and there's a good chance it might yours to.

X1-R is a fuel additive that's used by the best. NASA developed it for their 'Crawler'. Koenigsegg uses them for their cars (Only the fastest production car ever!) so it's well tested stuff, and I'm telling you, it does wonders for your engine. Not only does it clean out build-ups and dirt, it also raises the octane level of your gas so the car will be more alert. More HP

jp55soul

where do you get X1-R

...I'd be careful using any stuff used on that flying tile-scaffolding - built on cheapest bids. But if my mate suggests tHat, what can I say?

Phatsta

Not to worry... I'm not the only one who has tested it. All I can say is if there ever was a wonder-potion for cars then this is it. Under just one circumstance: Do not overfill with this stuff coz you'd have a race car for about 5 mins before the engine blows

Maybe you should try it for your old Jeep Wiking, might do wonders

Wiking

It won the *****, but can it withstand this?

But on the max putputt issue: I'd also try these snake oils before injector replacement, not on healthy engine.

One of my friends believes that one xr oil additive saves gas 5-10%... cannot but wonder as friction (where oil has some pwr over) is less that 0.5%. Either the xr -snakeoil is better than promised, or I am an ol fool hillybilly... I feel like the latter.

Phatsta

I can't see why it'd hurt..?

What the fuel additive does is to clean out anything that is not metal, or so I've understood anyway. don't know exactly how it works but to my knowledge nothing bad can come out of it.

But the oil additive, that's a different story. The oil additive is suppose to rebuild the cylinder walls with a thin layer of I-don't-know-what-it-is, which results in lowered friction, less heat, less resistance and therefore is suppose to increase gas milage. But with old engines that has run half a lifetime, I'd say it's up to the owner to risk tinker with such additives. I've tried the oil additive as well and the only thing I noticed was that the valve lifters stopped ticking earlier than usual (during oil pressure build-up) so I can't see anything wrong with it. But as I said, it's up to the owner to decide.

My dad poured some of the oil additive into our air compressor and the old pice of s**t actually went almost silent , from being in the same level as an airplane or something so it must have some good effects.

Wiking

Is it still plugged to wall outlet? ...yes I know some good stuffs, but just know whattodo and how to växla.

Well, jeep is so tired its been retired and he stands instead, seen here at my södra cal ranch...:

jp55soul

hey do you think the redline stuff will work just as well as X1-R

Phatsta

Have no idea, haven't tested any Redline products. But I do know the STP products leaves a lot of stuff behind when it gets burnt. X1-R doesn't. Test it yourself: Pour a little additive on a spoon and set it on fire. Let it burn out and see what's left on the spoon. That'll give you an idea of what product is the better.

RapidRoy

Couldn't find the X1-R locallly, so picked up a bottle of Red Line complete fuel system cleaner. I'll report on results in a couple of weeks. I have used their "water wetter" in the past with good ressults.

TommyT

We don't have X1-R locally either, but I put some Techron fuel system cleaner in. The local mechanics and parts stores swear by this stuff. Better be good for $12 a bottle. I already use Mobil One synthetic oil, no need for oil additives in my opinion.
