Check engine light?????

[gtdriver990]

i just put on my new bbk Lt headers and i took out all the smog pump hoses and pluged the vaccumes off, but i still have the smog pump on the belt system, its just blowing air, i have to wait for my delete kit to come but it seems like once the car gets to normal operating temperature the check engine light comes on, does anyone else have this problem with the smog pump or long tubees?????
if anyone has any ideas please let me know i dont know if i should drive my car?????

get a code checker. If it is a 313 like mine was, it was to little egr flow. I found that the egr vacuum had come off. Once plugged in, the light went out. Really you can't do anything until you read the codes.

Check your vaccum lines and make sure you have the red one hooked up to the intake, and the green to the EGR valve.

Your CE light is more than likely an EGR problem of some kind and it'll be ok to drive your car until you can get it fixed. Also make sure you plug the vac. line coming off of the smog pump so you wont have a leak.

hmm, maybe you forgot to connect something? did you run 02 extensions? maybe the company sent you those weird resistor ones for the 4.6's the MIL thing. if I were you I'd check the intake (rice term, not manifold) to see if one of the connectors from like the Intake Air sensor to the harness might be off, or whatever, somethign simple. Cause when I dropped in my BBK LT's I pulled out the intake and all that airbox **** to make room for my mickey mouse job on the smog system.

thanks guys i checked all the wires and everything i pluged up the two vac lines that went into the smog system and i checked the egr valve and the light stays off untill the car hits normal operating temperature then it comes on. i was wondering if the best thing would be to hook the smog back up, because all i need is one rubber hose or something that can hold the heat and then the light should stay off right????????????????
and does anyone know where to get a hose to go from the h-pipe to the smog in the engine bay????????????????????

guys i just went into my car again and i saw that i have cracked the plasticty vacume line, the green one that goes to the egr, it was under a plastic covering so i missed it, but now i am faced with the problem of fixing it waht should i do, tape??? because i doubt my ford store would ever be aable to get a single egr vaccume line so i have to look for other alterinitives?????????

The check engine light is coming on because it's reading to much carbon monoxide in your exhaust and the air pump is suppose to clean up the exhaust gases. I have that same problem with my car. I have lt headers and I just pluged all the hoses to the air pump including the one on my h pipe.

My vacuum tube that allows the air to go through the vents broke. I simply butted them together, and used electrical tape to keep the together.

Not the best fix, but it works.

Another thing you could do is cut the vacuum line where it cracked, then remove one side from the car, and take it to ace hardware or a local hobby shop, and find a thin brass tube that will fit INSIDE the vacuum line. They should have a size that will fit in there very snug. Then put some tape around it & you are good to go. I did that for a vacuum line that I accidently cut on my brothers bronco.

you could get like an inch of rubber vacuum line and use that as a connector. I don't have the tube that goes into the Hpipe on my car, I'm running a DR gas X no cats, that tube is there to heat up the cats so they work sooner. I do have the smog pump connected to my heads though.

since when did the computer start checking CO?? the comp. reads O2.

the air injection puts air into the heads during warmup(before O2 sensor input) and routes the air to the cats when the engine is warm (after O2 sensor input). during deceleration and certain other times the air is dumped back to the atmosphere. that is how the AIR system works. if you get a code for O2 rich during AIR test, it's because your AIR system is disconnected and the comp during the test is looking for full LEAN.

i'm not trying to be a prick or anything.
