Most likely weak ignition coils, especially if they have over 30,000 miles on them.
If your car is a 2004-2005 model with more than 50,000 miles on it, have your compression tested before you start swapping parts.

Could be weak ignition coils.
Could be fouled spark plugs.
Could be worn out spark plug wires.
Could be a worn out apex seal.
Could be a coolant leak inside one of your rotor housings.
Could be a crack around one of your spark plugs loosing compression.

Could be a whole bunch of different things.

Would help a bit to know what year you car is, and which transmission it has, plus, what servicing you've done to it in the past year or two.

BC.

Good Quote.

Imagine somebody coming here daily, in fact it is often multiple people daily, asking if not demanding the same information over and over again. We are not your on demand servants. We are people just like you with other priorities and demands in our lives, limited time, our own personal interests for being here, etc. Why should we spend that time catering to people that come here seeking instant gratification?

That leaves us with two options. We can either ignore you completely or we can tell that the info is here if you bother to make the effort. However, over several years of telling people this you eventually get fed up dealing with the continuous stream of people seeking instant gratification yet you still would rather point them in the right direction so you just bark at them to get the point across. Imagine someone coming to your house, going to your living room, pulling their pants down, and taking a dump right there on the carpet just because they didn't know any better. You might be annoyed and yet also understanding because they didn't know any better. Now imagine this being a different person doing this every day. It wouldn't be long before you just as soon they go away and never come back.

Almost every day there is some clueless dolt posting a tech or troubleshooting question in the DiY area, despite there being a sticky thread at the top saying to only post threads there with DIY instructions and subsequent discussion of same. The real issue is that people think they are free to just come here and do as they damn well please and there's no need for etiquette, rules, structure, or organization unless it serves their own personal interest.

Well guess what? We're not here to cater to new uninformed people that come in here trampling all over everything regardless if they're ignorant, just don't care, or whatever. This is like any social community and so if you make waves you better expect to deal with it. If you don't like it then get the f' out because the established community could care less about some newbie whining about not getting what they want immediately. We do care about you clogging up the search engine with useless threads on already established subjects, which there is a dedicated thread on this very subject in this same forum area no less. It took me 10 minutes to explain this. Now imagine multiple people daily requiring it, so you make a Sticky thread at the top that says "read this first" and yet every single new person just like yourself thinks they are beyond trying to fit in properly so that this forum operates smoothly for all of us.

You probably don't read Japanese, but the line in my sig is a well known Japanese proverb that reads "the nail that sticks out gets hammered". You made yourself that nail.

Although it may be popular to discuss the wave of "noobs" that arrive every now and then, and criticize them, there are waves of other types of people around here I find myself humored and annoyed by at the exact same time.

Yeah some topics are worth revisiting, others are not. Some info is difficult to find without knowing the proper search terms, etc. so I know it can be a bit daunting. I am only critical of noobs who don't make any attempt to search. If they search even a little and are willing to learn I will give my 2 cents and try to point them in the right direction. But a subject like this has been covered a 100 times over and there are stickies addressing it so it's pointless.

wow. Are you sure you've thought this through? Have you even had the engine codes read? Have you checked other areas (ie cat converter)? Tested your plugs/coils to see if they're ok/installed correctly?

Jussayin...

don't we all .... n00bs make the best customers so you can't expect the general forum membership to have the same interests and motives at heart as a forum vendor might. As such, the particular types of people around here that you mention likely impact the two differently as well.

I completely disagree with that sentiment.

N00bs don't really know what they want, they don't know how to get it, they don't understand what it is they are buying and they will completely saturate your time looking for answers to the questions that they should have posited way before they spent their money.
Then, when they get half "enlightened" on the subject, n00bs get buyer's remorse and want to make "lemons into lemonade" in their mind by trying to force their purchase into performing a function for which it wasn't designed.
As I've noted elsewhere, the more you give, the more they will take until they have exhausted your ability to satisfy them at which point they will bash you for not having stopped them from purchasing your product/service in the first place!

No, as Sy Syms said: "An educated consumer is our best customer."

While there is much wisdom in your statement, there was also a heavy dose of sarcasm, cynicism, and facetiousness in mine. Even the most knowledgable rotary people, both on and off this forum, disagree on many things so the answers are not always so clear. I was referring more to a n00bs gullibility factor. Just look at how many are quick to dump a gallon of seafoam through their engine without disconnecting their cat pipe. In reality most vendors work hard at convincing the uneducated customer that they are the informed source that should be listened to. The vendor may even believe this to be true even when it may not be. The bottom line is a vendor doesn't survive without a minimum sales volume. As such a pinch of reality salt is always in order.

Understood.

Provided that profit is the primary motivating for a vendor, which is generally the model.

But not always.

Sometimes, just breaking even is reward enough.
