3.4 Pacesetter Headers

No, vacuum leaks can be anywhere after the MAF sensor. Just make sure the air hose clamps at the MAF and throttle body are not loose, and that the tubes normally attached to the intake manifold are connected. Then confirm that the IAT (intake air temperature) sensor, MAP sensor, EGR valve, TP Sensor, Idle Air Control are all plugged in.

Check hoses going to the heater core, and anything near the headers that could have been disturbed during the installation.

Sounds like I will be going back to the shop to demand an inspection...

Until then: I'm not going to blow up am I?

probly not. thats most likely where the cel is coming from. if they just cut and spliced in more wire, youre gonna get a code. youre also gonna need a new sensor and the proper harness extension.

Pacesetter just sent out extension wiring. Where can you get a harness?

Here is the video link: http://www.youtube.com/watch?v=STy3EgDDv9o

Lemme know what your guys' thoughts are.

Clean Alero and nice sound. The idle is very odd though, does the car perform normally otherwise? (You said you didn't feel any gains?).

Dude where the hell can I go to be wearing shorts right now? Snow is in the forecast tomorrow!

Keep us up to day on what the problem is

Not bad. Wish my alero was a clean as yours lol. I wonder if the PCM just needs to adjust to the change, but then again if it did, your car wouldnt be surging like that I would assume...just a hiccup here and there at most.

I think that's the one you'd need.

Almost sounds like it has a miss, try doing a power balance test. If you search for those exact words I think I've explained it all on here before.

edit: This is where I talked about it, not a super great explanation but if you're mechanically inclined you should be able to figure it out

anyone else notice the taillights dimming when the engine surged? no idea if its related or not, but probly not a good thing.

[Lucalare]

It's because when the engine slows down it doesn't make as much power off the alternator. With a stock spec alternator your lights get a little dimmer even at idle, so really that's nothing bad.

[Ttop191]

^ that exactly

[whiterider00]

thats what i was thinking, but i didnt realize it cud be that noticable.

[Lucalare]

Normally it wouldn't be but that engine is slowing down a lot more than it should.

Hell Paso, TX. Welcome to sun city and the desert. I hate it here.

The car runs-as far as performing normally. But I cannot tell you because something is out of whack with it right now.

If it needed an extension harness wouldn't pacesetter have given a warning? Why would splicing in more wire throw a code? So long as it gets the proper wattage shouldn't it just function?

I thought that the PCM would need to adjust but this surging is pretty troublesome-and it should have corrected by now. Does it at idling or when I come to a stop. If that O2 sensor is malfunctioning, could that throw off the idle as well? A sensor issue seems much easier to fix than finding a leak...

Temps seem to run normal to lower at times, with higher spikes...worried about the radiator leak. Could the headers opening up the airway keep the engine temps cooler though?

[Ttop191]

if you alter the sensor wiring you change the resistance of the it's output wiring therefore throwing off the signal voltage it is sending to the PCM, sounds to me like there is a loose connection in that splicing they did, so the signal is constantly changing and the pcm is trying to adjust fuel levels based off the incorrect signals it is receiving

[datwonguy]

well isnt that sweet!!

[Ttop191]

^ how long ago did you buy them, when pacesetter first released these they were having the tranny clearance issues, but they have since fixed that. Also, i know a few people on GAGT forums just shaved off some of the tranny housing to fit in the first batch of pacesetters, as far as i know, none of them have had issues yet and it's been a few years

[XanderWiFi]

That makes sense regarding the wiring. It would be awesome if that were the remedy to this medly of problems. I just bought them last week, the version that corrected the clearance issue.

However, it does sound like that knock around like hell. Sounds like my engine is falling out. Any solutions to that?

Appreciate the compliments thus far though. Believe it or not, my car is uber dirty right now too. Was almost ashamed to post the video about it. I will post something much nicer once I get everything in line. My wife told me last night: "Can't you please just leave Angel alone? I worry the next mod you do may put her in an early grave. She is eight years old..." I said: "Um...I'll see honey." Lol.

[Ttop191]

just listened to the video again didn't sound like a knock at all, more like a rattling heat shield
