alright here is my problem my 88 iroc just developed a wierd clicking sound and it is comming from the tpi i believe it almost sounds like lifter knocking but it seems to be coming from part of my intake does ne one have any idea what this problem might be caused by?

 

Well, the only moving parts on the intake would be the injectors. When they open and close, they're known to tick. Mine are loud as heck! ...but not sure why it would've started all of a sudden. Any chance it's been doin' it for awhile and you didn't notice?

 

could it be the fact that it was being drivin hard in cold weather....and is there ne way to stop the ticking??

 

Not that I know of. Doesn't mean there isn't, I just don't know how. Shouldn't be a problem though..... why, ...how loud IS it???

 

its loud as hell you can hear it over the exhaust system and it speeds up the higher the rpms go

 

it might be an exhaust leak right at the head. mine did the same thing.
once it warms up, put your hand over the exhaust manifold. feel for the air puffing out.

Goodluck,
Mike

 

after taking a closer look at the problem it does seem to be coming from the injectors/ intake manifold area and when you feel the injectors you can feel the ticking vibrating them does ne one have ne help with this or ideas on how to fix it would it be possible to just try the fuel injector cleaner? or would that mess it up more?

 

id have a VIC performed on your car... chances are its all stock right? it will help your car out alot... i did a VIC on my 383 and it runs a lot smoother and feels more powerful (car sat for 2 years and has a 383 from 2000 in it)

 

what exactly is a VIC?? I won't have a chance to do it for awhile cause i'm going back to base off of leave but i'll do it when i get back to illinois

 

Hm, I have what he seems to be describing as well. What's a VIC?

 

ill look exactly what the stuff was when im at work today,
but you basically unplug the fuel pump, and hook up a bottle filled with this fluid right at the fuel pressure regulator i believe it was.... and let the car idle running off that until the bottle is empty (about 4 minutes) then i hooked back up the fuel pump then i got some intake cleaner, cleaned the throttle body and sprayed it inside the manifold with the engine running and revving it while doing so (dont overkill) and then i put some fuel injector cleaner in the gas tank.

but, my motor was built in 2000... and sat for 2 years in a driveway, it ran fine and strong its just the other day i decided to see if it would make a noticeable difference in my car....

and right when i started it it idled different, had better throttle response and has a noticeable power increase.
