My dad has a chrysler sebring and it is missing really bad and before we look into the problem we were going to try some fuel injector cleaner to see if that would help at all... anyone thoughts ideas suggestions

Plugs, wires, cap-rotor.

Seafoam would be a great idea, unless its a high milage engine.

Possibly bad gas? Check vacuum lines.... 8)

the motor has 84k and its been through two tanks of 93 and still doin it...

sea foam huh./... ill look into that

Does that car have the almighty 420a in it also? I agree with adam check for a vacuum leak somewhere, and you might test out the coil and what not!

Unless it calls for 93, you are wasting your $$. Stick with 87 octane.

Seafoam would be ok, give it a try. I have used it and heard nothing but great reviews. ~6-7 bucks @ one of the auto stores....

1/3 in the gas.
1/3 in the oil.
1/3 directly injected in a vacuum source on the intake manifold.

I run a tank of premium every once in a while, just to keep everything clean. Does the same thing as fuel treatment, and just a little cheaper. And in that Ranger I had ('98), if I was driving to NC and didn't put at least 89 in it, the valves would knock going up the mountains.

How is it the same as fuel treatment? Higher octane is just more resistant to detonation/knock. I agree with Adam, you're wasting your money if your engine dosen't call for it.

[C_Note]

Higher octanes contain a higher amount of detergents, which are used and regulated by the EPA to keep fuel systems clean. It's just something I've always done, and when they started selling fuel treatments, I found they did no better than my occasional tank of 89, so that tells me they do pretty much the same thing.

It's not a waste of money, to me. $0.06 more on the gallon, which comes out to around 75 cents, depending on what I'm driving, once every 4-6 months.

Some gasoline such as Chevron w/Techron, have cleaners in them, the same if you buy 87 or 91 or even 93. That is a main reason I buy gas there.

As far as the octane rating goes, the higher the # the more resistant the fuel is to combustion. Thats why it prevents detonation. Most higher compression motors, or boosted applications need/recomend 91 or above.

I believe since you have a higher milage engine, you have a "healthier" degree of carbon builup. Thus increasing your compression. Therefore running a higher octane may prevent the valves from knocking.

My Ranger only had 50k on it when I sold it, most of which were driving from NC > OH, and back. They knocked even when it was at 20k... I don't know why. I think that whole crop of Ford Truck engines (96-98 ) were a bad batch (mine was a 98 with the 4.0L).

My dad's old dodge was the same way. Butt it would only do it if we bought the gas from wv before we made a trip. If we bought it from Ohio it was better gas.
