car's running rich
car's running rich lately my car has been running extremely rich. whenever you let off the gas it's like a gun keeps going off. it's also sucking down gas incredibly. the only things i've done to it are an slp cai and slp loudmouth exhaust. the opti is on its way out but would that do it? just a set of plugs? or could the intake or exhaust be doing it? but that wouldn't make sense since cai's and catbacks claim to increase mpg. anyone have any ideas?

as posted in other threads, my car dies whenever it rains. obviously the opti has a defect and water is getting in too easily. maybe just a small crack in the cap but i'm getting sick of it. my dad keeps saying its the slp cai. he says that since the filters are hidden under the wheel wells not enough air is getting in. idk but that doesn't seem right. cai's are supposed to get better air flow but the way the slp cai goes in is kinda stupid. it's basically blocked off from all air flow.
one final question, once in a while, occuring more often now, when i try and start the car nothing happens. its a standard and each time i make sure the clutch is in all the way. i have to turn the key a few times and then it turns over and fires up. any idea what this is? starter maybe?

Your cap getting moisture in it could be causing your rich condition.
Your dead key turns could be caused by a bad ICM, bad ignition switch, or Vats.
I would get a new AC Delco/Delphi opti, new wires, new plugs, new coil, perform the ICM cooling mod, clean the MAF, new AC Delco o2 sensors (if never replaced).

idk about a coil or the ICM coolind mod
cleaning the MAF is very ease
o2 sensors like 120 for 2....
so get ready to dig deep!!!
but ss.slp.ls1 knows his ****... i am doing everything what he told me and everything is coming out good.. some bumps in the road with the water pump (i had to replace it) but other than that i would listen to him

Yes, they can be sort of expensive. This site has good write-ups and has been referenced many times. Helps out tremendously for those who haven't tackled certain aspects of repair/modification on their LT1s: http://shbox.com/1/4th_gen_tech1.html
Not trying to hijack here, but it is sort of relevant. Would Bosch O2s cause it to run tool rich? Is that a common complaint? Also, the LPP copy headers I have moved one of the O2s way down the pipe from its old location on the passenger side...could that be a problem? The drivers side is still pretty much where it was originally. I have a '93 by the way.

Yea, I could relocate it myself even, I just would rather not if it can be tuned to accommodate or something. I was just curious if that could cause a problem...the least of mine right now unfortunately :-p Sorry for the hijack...
