A friend of mine has a ´96 Cavalier 2.2L and it´s not acting too friendly. I don´t feel like typing too much here tonight, as I am quite tired, but just want to know something. Is there a ~simple~ way to check if the injectors are working at their full capacity? I´m going to be doing a bit of work on it for them, but only after I figure out the extent of damage caused by not having a tune-up in over three years with only one oil change and effectively no air filter.

I would say just get one of those fuel injector cleaners that you put into the full gas tank to clean them out. If its still a problem i cant help ya :cool:

Was planning on doing that, but was just wondering to get some definate proof of their condition. I will be doing a compression test soon and that may just render anything else pointless.

the only real way to check to see how well they´re sprayin is to take them out. other than that, just dump some injector cleaner in like Sk8ter suggested. :-? one oil change and no air cleaner will kill a car fast. do the compression test to see what kind of numbers you get...

after all this sabotage the car, because it´s weak and pathetic. Cavaliers suck 115 hp 2.2L? pathetic. ;-)

Multiport fuel injection? Have the injectors professionally cleaned if you have any doubts... For about $75 to $100, a shop will run this really nasty cleaner through the injectors that will eat any crud or varnish that may cause a restriction in the injector, and/or mess up the spray pattern. Worked wonders on my 3.0L in my Taurus.

The fuel injector is the most reliable part of the system, so personally, I´d look elsewhere before zeroing in on the injectors. Can you pull the codes out of the computer? The diagnostic link is probably located under the steering column, underneath the trim panel. (Just a guess - but an educated one)

Let me know if you need help on how to pull the codes... Does the car have a "Service Engine Soon" or "Check Engine" light?

Well, my friend doesn´t really have the money for that right now, so I´m trying some home remedy type things.

I am looking elsewhere, pretty much everywhere as a matter of fact. It does have a check engine light, but it´s not come on in a while.

The reason I´m thinking injectors is because they said the last time they put some fuel injector cleaner in the car it helped out quite a bit, but I have a strong feeling that there are a few other things wrong with the car. I will know more when I personally take the car out for my own personal test drive.
