So I did the 3" bl on my buddy's 06, finished on Saturday, now he's got a cel on, don't have a code reader available at present, but is there anything we should check to see if we missed or ****ed up and that's what is causing the light?

 

Might have knocked a plug loose or something Or its just a coincidence

 

It's PROBABLY just a coincidence, I'm thinking, no driveability issues... But cel is never good...

 

The fuel EVAP tube right near the driverside wheelwell in the front. Very common for it to become disconnected.

 

Would that cause a instant cel? One that stays on even with a restart and such? What am I looking for when looking for it?

 

Yes. It'll be a disconnected tube.

 

Right on or near the drivers fender? Sound like a vacuum leak or anything like that?

 

 

Ool thanks Trent, will fixing that make the cel turn off right away or does the code hae to be cleared?

 

You'll have to clear it. Undo the negative battery cables, turn on the headlight switch for 30 seconds and then reconnect everything and it will be gone.

Thats if its that tube thats unplugged, it could be something else.

 

Same location for 3.0 and 4.0?

 

Tube is still connected :(

 

Go to autozone and get it read then...

 

ah, i cleared it last night, hasn't come back since... so we will see... if it was something important or something still wrong, it'll come back i'm sure

 

Mine stays on for about 6 days, then leaves for 1, then back for six, out for one, etc. Starting to **** me off lol

 

light came back on last night... wondering, does the gas cap cause a CEL on our trucks? the way we had to do the vent tube on the gas tank makes me wonder...

 

I know these vehicles are completely different, but in my old cavalier, if I overtightened or forgot to put my gas cap on, it would give me a CEL. I guess I wouldn't completely rule it out.

 

there are over 500 trouble codes, instead of guessing go get it scanned and then we can hemp you out more

 

it's a matter of when my buddy can get his truck to somewhere to get it scanned...

 

so, since i got my new tires on my truck, my low tire pressure light has been on, of course i didn't think to get new pressure monitors or anything... how do i disable that light temporarily (untill i put the stock rims back on for what ever reason)

 

No way to do it as far as I know, I looked into it when putting my new wheels/tires on.

 

so i am going to have to get new (or steal the ones from my stock rims) and install inside my new rims then eh?

can you pair an additional set of monitors to your truck?

 

You have to get new bands I believe. If it were me I would just throw them all in the spare if that was possible.

 

The gas cap (if not sealed correctly) will give a CEL. I replaced mine because it kept throwing codes.

As for what your buddies CEL issue is, get it scanned already. OBDII code readers come with all the bells and whistles now, but there are some basic ones out there that will run you $50 on sale and will let you read/clear codes. I got mine on sale at Crappy Tire a few years back. I know Princess Auto has sales on them all the time.

As for your TMPS light........if you have aftermarket rims, it'll be there. Black electrical tape is your friend, or remove the warning light bulb. LOL

 

problem is, my stock rims have nitrogen in them, and my new rims have air, and i don't want to dump the nitrogen... i'll buy new sensors if i have to... but i odn't know if i can pair new ones to my truck... i can't see not being able to... being some trucks i'm sure have winter tires and summer tires... i'm going with the same basic idea

the truck with the CEL is actually mine, i just saidf it was a friends, so i could post all the new mods at once, while keeping it a secret...

i am 99% sure it was the gas line, it was dripping gas out while filling the tank, from the splice/extension, i tightened the hose clamp, problem solved, just want to get it read before i clear it again
