Was driving back home today and came up to a stop sign and the truck just started missing bad, no power at all. I did check the spark plug wires to make sure that one of those did not come off. Does anyone have any other suggestions.

Thanks John

I failed to mention that the truck idels great it is only when accecleration.

The write-up below is by D.R. at N4W

Is your truck running rough?
Does it ping?
Have you lost MPG?
Have you ever had an internal engine cleaning?
Maybe it's time to Seafoam the engine. After the results I had with my Camaro on this, I'll be doing it on the Xterra that's pinging like mad and the MPG has gone to heck. It's an easy process that will take just a couple hours of your time, and cost about $25. Repair shops charge as much as $250 for almost exactly the same service you can do yourself.


- Buy 2 cans of Seafoam and 1 can of Seafoam Deep Creep spray.
- Put one can in a full tank of gas
- Put half of the second one in your oil
- Drive 100-150 miles.
- Park the truck and pull the vacuum line going to the brake booster.
- Start the truck. The idle may be racing, or it might not want to idle at all. If it's idling high, don't worry about it. Right now you have a huge vacuum leak. If it's stumbling, blip the throttle by hand enough to keep it running as you do the next step.
- Trickle 2/3 of the remaining 8 oz of seafoam down that line. You may need to have a friend there with a hand on the throttle giving it just enough gas to keep it running.
- With the final 1/3 of the remaining half can, now just dump it down the vaccum line. This should kill the engine. If not, shut it off ASAP after doing this.
- Use seafoam deep creep spray and pull the air intake tube, push the throttle butterfly back and spray about 1/3 can down the intake and let it sit as well.
- Reassemble your intake and put the brake vacuum line back on.
- Let the truck sit 30 minutes.
- Start the truck back up (it will start hard)
- Let the truck idle 15 minutes. If it doesn't want to idle, work the throttle a little bit to keep it running, but do not rev hard on it during this period. The truck may smoke a considerable amount during this time. Don't worry, it's not going to hurt anything.
- Go out and take it on a drive - flog it. You'll make lots and lots of white smoke.
- After a few wide open throttle accelerations, the smoke will clear and you'll end up with a better running truck. This cleans all the carbon buildup on the inside of the engine.
- Lastly, change your oil. This will be the blackest, nastiest oil you drain out of your truck.

This stuff is a petroleum product and will not harm sensors, cats, etc. I know it's weird to think about dumping something like this in the oil, but with the difference it made on my car, I'm sold on this stuff. The pinging went away, as did a flat spot in my rpm range under acceleration. The car also is idling a lot smoother.

Hey I don't know man... I've never had the problem with the Frontier. I learn by doing... The cool way is to borrow a heat sensing gun and shoot the headers to see which one ain't firing.

Type A tranny fluid or even water can be used like Seafoam to blow out carbon. I've done it many times.

... To prevent carbon build up I run 4oz of pennzoil 2 stroke Out board oil in twenty gallons of gasoline.

Have a good one while you can still laugh about it.. Don S..

"I don't think there's any question that speculators in the oil markets have taken prices higher than they would be otherwise," Rep. Joe L. Barton of Texas said. "I think there ought to be new rules."

The energy bill is still in effect and we’re still being shafted.

did you pull the spark plugs and check them? mine was doing the same thing and when i pulled them i found that one of the plugs had a small crack in the porcelain, and it made an AWFUL miss!!

I use the Pennzoil outboard two stroke oil all the time in my Jeep.  The Jeep tends to run rich and carbon up running at high altitudes above 9,000ft. and bad at 14,000ft. I’m too lazy to retune due to many altitude changes. I live at about 700 ft. The OB oil has cleaners, anti oxidizing additives and is very low in ash content so it doesn’t leave carbon.  The additives do the job. Presently I’m using Lucas fuel treatment in the Frontier. I bought  26.25 gallons of 87 10% Ethanol unleaded … $100.00 and felt lucky to get it at that price… that’s $3.809 /gal.

BTW sears just put the craftsman #3450466 laser 1000 *F heat sensor  gun on sale @ $59.99. The wife just now got me one!

 I am now in the futures market,… hording if you will, buying things I will need in the future because the real American inflation rate is approaching nine percent And ‘fixin’ to get worse!
