weird problem with engine

[Anthony1238]

I'm pretty sure this might have been covered before but i didn't get a good answear.... to start my car was miss firing so i narrowed it down to my my plug wires. I changed them and the plugs. i get spark to all cylinders... it car ran goot for about 10 miles and it was great, it was like a brand new car... then i started it the other day and it was bogging down and lost HP.. i step in the gas and it was like it was running on 5 cylinders.. i put fuel injector cleaner in my gas tank and after a few minutes of driving it opened back up... that lasted about 5 days, now its back to bogging down again... is it a clogged fuel injector/ filter...so im thinking fuel injector but want to narrow it down...thanks for the help headbang

Have you read your codes yet? That's the first thing you should do before spending another penny. You can do it yourself with something as simple as a paperclip or short piece of wire. There are links to sites with instructions on how to do so in my signature. Let us know what you get for codes (the actual numbers will help a lot), and we'll see what we can help you figure out from there.

i ran my codes and got all 11's and the CEL wasn't on... this problem happens ?sporaticly?... it comes and goes as it feels...

OK, go back to the codes pages and run the KOER tests, including a cylinder balance test to see if you can narrow down the source of the miss. BTW, what plugs & wires did you install?

OK i ran a cylinder balance test and it showed the #2 cylinder was out... i know it has spark and i also used a stethascope and check the fuel injector and it wasn'y ticking like the others... so i'm sure it's the injector... i tried cleaning it and nother happens... and i also got a quote of 75.00 to presureize them and clean them... and 89.00 for new ones... i think i'm just gonna get new ones and put them in my self... if there is any thing special i should know about changing them thed more advice the better... thanks for the help
