why do you think it is the injectors?
no offense, but you don't sound like someone that knows what they are doing under the hood, but yet you've mentioned the injectors half a dozen times... What makes you think the injectors are the problem?

You can pull the entire fuel rail off, and slide a piece of cardboard under the injectors and watch each one spray fuel as the engine turns over. That will give you the visual to see if they are spraying and how they are spraying. Each injector should spray like the other ones. If one is really different, like a drizzle, and not a spray, then that injector is bad.

You can also get your multi meter out and test the Ohms. I believe there is a "how to" in the sticky at the top of the tech page. Again, they should all be about the same, and they should all be about 11 or 12. Up to 15 is "acceptable" Anything below 10, or about 15 should be replaced. Some people don't replace them because they still "work" I always do.


Since you just bought this car, and don't know anything about it, then you need to start with the basic stuff.
new spark plugs.
new spark plug wires
new cap, rotor, fuel filter etc etc etc etc.

I would suggest cleaning the MAF while you are at it.
I also suggest installing a fuel pressure gauge. Even if it isn't the problem this time, it is good to know what is going on with your fuel when you have problems down the road.

you should also pull the fuel pump out to inspect the fuel tank to see if there is sludge crap in there and to see how nasty the sock is at the end of the pump. It started its life off white, so if it is black, then replace it.

Once you get all of that done, then you need go over the entire thing with a fine tooth comb to check for vacuum leaks.
you can remove the emissions stuff if you want to. It helps get rid of some of the vacuum lines and are old and cracking and leaking. There are plenty of write ups on the internet to tell you how to do it.

Somewhere in there, I highly suggest doing a compression test. I doubt it is the problem this time, but it is good to know where your numbers are at. (technically, this is something that you should have done before you bought the car)


How many miles are on the car?
What condition was it in when you bought it? Did it have this problem before you bought it? How long did it run and drive perfectly before this issue started?
Do you know any history about the car? did it sit for a year? was it driven everyday? did grandma own it? or some punk kid?
Does it have any aftermarket parts on it? Things like exhaust?
Manual? Automatic?
How much did you pay for it?
