Wow.. You really went on facebook, looked me up, and looked at my status from over 4 months ago?!?

Yup, and the best thing about it, I got paid to do it! What can I say, I was bored at work.

I'm not sure if you have a disability or something but us includes myself so yes I have gotten it when I send you know me than me.

to the op.....your are a tool.. Show the org some respect, post some info when people ask you, and stop acting like the org owes you an answer. knowing that you have a 42 trim turbo and a wastegate wont help anyone help you...for all we know it could be on a car that has a 6.7 litre, and your problem could be that the turbo is too small and ur and idiot. now stop acting like this is qwk ln2's fault, admit that you coulda gone about things a different way, and maybe people will help you.

Yes, I do realize there is a lot of things I could have done differently to avoid all this and should have

See, this is kinda like an AA meeting... Step one is admitting you have a problem. Step two is to fill out your profile/registry to the best of your abilities, and to make it as accurate as possible. More steps to follow, but we will start here.

Congratulations Retards! Another famous post on the j-body forms from retarded people, people willing to put in there O'2cents, and the people with actual knowledge that wonder why they get on this forum and deal with these retarded people.

Alright my car moved from backfiring to now misfiring all throughout the rpm range. I smell fuel through the exhaust so that would make me think the plugs aren't firing but i just put in new spark plugs and still have the same exact problem so I check for spark and have spark on all 4 cylinders. The motor sounds fine you can just hear the misfire out of the exhaust and its extremely laggy to where its undriveable

And it is a 2003 pontiac sunfire with the l4 2.2 ecotec with a 42trim turbo, tial wastegate, and 42lbs injectors

Sounds like the tune is off. Have you reinstalled your primary O2 sensor yet? Have you retuned since you installed the wastegate? What is your AFR, TPS, and timing at when this happens?

I have a appointment friday to have a exhaust bung welded on there and then it will be hooked up. It is around 15 afr and any tps, rpm, timing it does it. I understand I need my 02 for correct tuning but I was running for a month without it so I don't think that would cause it, I disconnected the battery just incase the computer "learned" something that was throwing it off. I did not retune for the wastegate though. How would that affect it though? I'm not sure, thanks.

Due to your PCM being Alpha N(Fueling based off of TPS), almost any change in boost pressure will affect the tune. Your new wastegate is more than likely opening/closing at a different load and RPM than your old one. That being said, since your fuel maps are based off the TPS and not the MAP, the computer does not know the difference between the old and new. Make sence?

If I were you, I would baby it until you get the O2 reinstalled, and then retune accordingly.

Alright I understand. But would that affect the misfiring at idle and all throughout the rpm between boosting and non boosting. Before it was only 3800rpm. Then it was only under full boost. Now its 24/7

Well, with the tune being so far out of whack its hard to say. I would almost need to see a log it while it is doing it (would need ECT,IAT,TPS,WB o2,timing,knock, and the misfire all being datalogged). You said the plugs are new, what are they gapped to? Have you done a compression and leak down test? Also, how did you test and verify that you are getting spark on all 4 cyls?





P&P Tuning
420.5whp / 359.8wtq

Gapped to .30. They are srt4 double platinum plugs. I verified spark by doing the good old screwdriver test(sticking it in there and watching the arc between the valve cover, I saw and heard it). I have not done a compression check yet, I plan on doing that tomorrow

running rich? turn the boost up

Alright I compression checked it and for the first 3 strokes they all moved about the same but when continued to crank the number 3 piston had only 195 compression while the other had around 230. That wouldn't cause such a severe misfire though would it. My buddy pulled the plugs and one plug was completely clean while the others where covered with a layer of black. I wish I knew which cylinder it was pulled out of though

running rich? turn the boost up

Alright. Its fixed! The #4 injector wasn't firing

Yes. I got the really sh!tty bosch injectors that are suppose to plug to my car. Needless to say they did not so after grinding a little bit I got the clips to fit and I guess with my stock beat motor mounts moving back and forth it unplugged it. And you will be happy to know that I'm dropping my exhaust to have a bung put in tomorrow! How far should I put the 02 from the turbo

running rich? turn the boost up

12-18 inches should be good....

Alright. Thank you. And after I have the 02 hooked up I used the PE to tune it correct?
