Whats up? Havent posted in a while,
anyways so my set up b4 was a lid/SLP MAf/free mods and stock manifolds/cats and just an open Y(pulled off the I pipe) i dynoed 333hp 350tq.....the car ran PERFECT


so now i just installed some pacesetter long tubes with STRAIGHT pipes with some Dynomax bullets on the back, No X pipe no H just straight, my AIR tubes are just hanging there no tune nothing, im running rich as **** and the car runs like dog **** idk why!! to rich is it?? idk why the hell its running like that the car idles at around 500-800ish rpms and on start up it takes a while n is all kinds of fucked up,...also my coolant temp guage isnt working i replaced the switch but i think the wires or SOMTHING might be messed up, the fans allways stay on so idk if that has anything to do with it. The basic problem is WTH did i do wrong?? i need a tune? or what? has anyone else had this problem??

BTW ive had a long saturday night so sorry about all my typos/bla bla bla if you can understand this haha, please help me out

Could be a tune. I would check/possibly replace your plugs. A cracked plug could be contributing to the car running like ****. Just an idea.

most likely it's one of your ignition wires

I believe the coolant temp sensor is near the front bolt of the driver side header, probably unplugged.

Common problems after header installs>>>>plugs/wires

How about when the coolant sensor in the head is unplugged or the harness is melted/burnt/shorted it will run like ****. PCM relies on Coolant temperature switch for switch between open loop closed loop.

Pull the fuse for the AIR PUMP in the passenger side box. You will get a light but at least you will know that is not contributing. Also, what did you do with the egr?

You need to get a tune and have all the things you !'ed turned off.

Coolant temp guage will def. screw with the way your car runs. I had the same issue after my mods. My sensor wasn't working properly, so the car never knew how much coolant to run. End result is it runs very rich, plus the headers with no tune will have you rich also, typically. Get a tune and all your sensors/plugs/wires checked while your at it. Should be fine afterwards.
