Stalling and ticking??? Hey guys,
A friend of mines LS1 has a strange problem. It seems to stall out unless you give it lots of gas when putting it into first. This problem only seems to last a couple of minutes after the car is started up. Also we just noticed a rapid ticking noise coming from the intake manifold area. My guess was perhaps a bad injector or maybe the air system since he installed SLP long tubes and kept the emissions but didnt make the adapter plates. My only other guess was perhaps an arcing plug wire. Anyone have a clue... im pretty much clueless.
Thanks in advance,
Ben

I noticed the ticking coming from some sort of sensor or solenoid that is connected to the fuel line, some sort of blue and red clip electrical connection, and another connection going towards the maf. Does anyone know what this part is? The part says dephi 1997251 on it. Please help guys. Were lost.
Thanks,
Ben

make sure the air tube that goes down into the header is not broken. my friend's car had a crazy loud tick, just like yours, and ran crappy just like you said. that was it. the metal tube was broken off the flange. i'd definitley check both AIR fittings for breakage/tightness.
if it is broken bad like my friend's was, you could actually feel some exhaust making its way past. btw, don't stick your head under the hood too long w/ an exhaust leak, you'll get dizzy or pass out, lol

Sometimes it's hard to pinpoint the location of a sound. You might want to get a mechanic's stethoscope. They're pretty cheap at auto parts stores. Touch the probe onto the injectors and other parts until you find where it's loudest.
A problem with the AIR system leaking would probably be more constant and not have such a dramatic effect on driveability.

It's the tube and assembly that bolts down onto the top of the "log" part of the exhaust manifold (well, he has headers now). my friends was broken, so the exhuast getting by the little break made a horrible ticking sound. it also ran like crap too. Sounds a lot like yours problem.
I have included a picture of the passenger side air tube. check the red circled areas for leaks/ticking. if they are leaking, you can feel them.
***also check the drivers side tube as well****
good luck!

ben, i think that is the solenoid for the evaporative emissions canister (to purge gasoline vapor at certain times. i have a parts manual here, and i have a number:
1997278 for 01-02 ls1 engines. i've enclosed some pics
it is number (559) in the black and white pic
it would def cause stuff to run badly if it was clicking on and off. i dunno if you can unplug it without throwing a code. give it a try!

sure man, np, glad i could help. i tried looking in the pars manual for different years other than 01/02, but it still does not match the # you have. I really don't think they changed though. dunno why it could have gone bad. just luck i guess? lol.
well, good luck, tell me how it turns out.
