ok, so i got a header from pacesetter, and when i got it it didnt have the egr port, so essentially i couldnt install the header, but i didnt notice this untill after the whole thing was appart... and 2 of the three bolts on the cat snapped, so when my dad got home we drilled out the broken bolts extracted them and i am currently using different bolts and nuts to hold on the cat, buttttt when i started up the car after we fixed this problem.. it took forever to start and than when it finally did start it idled at 4000 rpms, and than the cel light came on and i cant figure out whats rong, i think i might have pinched a wire.. it will be back in my garage on the life tomorrow, does anyone know whats rong wiht my car?

 

you broke it? tough luck dude. try unplugging the battery for like an hour then plug it back in and see what happens

 

lol, yeah i broke it alright.. i think i am the only person with this wierd thing in this whole thread.. pacesetter hasnt had anyone complain of this at all yet.. i think i got the stupid car... i hope i just pinched a wire.. im so upset and frustrated its unbelievable

 

Sounds like the car is fucked. Maybe your fuel trim O2 sensor isn't incorrectly. Maybe you broke it.

 

i hope its somehting as easy as that.. it just happened like i started it up at one point and it was fine, and than the next time it was fucked..

 

I would try getting my hands on a code reader to see what is causing the CEL to come on. It won't tell you exactly what to do, but it will help shed light on the situation. Some autopart stores will rent or lend them to you.

 

yeah,. i bought one and i found out that one of the sensors in the back of the engine bay was unplugged, it musy have come undone when i took the sock manifold out.. it fixed everything

 

Huge leak, pinched wire.

 

it was a disconnected sensor!!!

 

Hehe... I know your pain. I did that last Saturday when I was wrenchin on the Mustang. I had the upper intake manifold off to re-torque the lower intake and to replace vacuum hoses. When I put everything back together I fired it up and it didn't want to idle for crap. After scratching my head for a few minutes and looking over the motor I found the Mass Air Sensor was unplugged. Doh! At least thats all it was right?

 

Out of curiousity, there is no EGR on your car, so what port are you talking about?

 

here, ill show u a picture,,.... im 75% sure it is an egr valve


And there is this little **** on top of it with a sensor pluged into it

 

New Sticky!
