A while ago...

I posted about my car misfiring or something.

Since then I have gotten new coil packs, and changed all of the plugs, i have also gone over all the vacuum lines and intake hoses and all that shebang.

shes stutters up until 3000 rpm.

could it be the maf?

Yes. Possibly the TPS or CAS, as well.

Just to be thorough, test your injectors. If a few are below spec, they could be spraying unneeded fuel at low rpms, causing a misfire.

I agree with Zlover, and would guess it might be the TPS. I had a similar problem.

How many times must we drill it into people's heads? SEARCH.














Here's your fish for the last time... (this is seriously the last time I give you an answer that's this easy to find).
http://www.ttzd.com/tech/diagnostictech.html

If you're asking if injectors will throw codes, the answer is no. Remove the connectors and take a multimeter to them... they should read 10-14 ohms. If it's lower, it's dumping fuel... if it's higher, it's not firing.

Hell, to make it easier for other searchers to find this in the future, he's some search terms
ECU Diagnostic Self-diagnostic Codes Injector Test

Its almost easy enough to not answer something if youre going to be a douche about it. some people dont have time to sit at the computer and go through very post that the search brings up. further more, if i knew what i was searching for i would have searched for it, so before being an ******* next time, keep some of that stuff in mind.

in response to the second part of your response to my question, that was rather helpful, and thank you.

LMFAO!

You don't have time to sit there and look but you have time to sit there and wait for someone to tell you? Are you daft?

And you didn't know what you were searching for? ECU codes, diagnostics, injector testing... all those terms would've given you results here and on twinturbo.net.
