wont idle!!
wont idle!! So my car has better sitting for about a couple months i had a codes for my o2's just replaced them, it fires but wont idle or idles horribly for 3 seconds and dies same as before i replaced them.Fuel pump is really loud when it primes does that mean its bad? I really need to get this car running asap and i have no idea were to start addressing this problem so id appreciate any help
. Oh the car is a 98 z28 m6 long tubes and lid
Also the car keeps "resetting" itself as if i would put the key from off to ON over and over

i put a gallon of gas in and i idled pretty good i guess my gauge is off, its stumbling a little so im still gonna change the plugs. Its still "resetting" itself anyone have any info on that?? when its does it RPMs oil pressure and bat. voltage drop. ABS inop light is on whats that mean?
No SES light I guess? There still may be a code in there so you might want to get it scanned somehow.
My friggin PCM isn't putting on an SES light and I'm only hitting on 4 cylinders....
Might have a clogged/dirty fuel filter too. Water in the gas maybe from sitting.

actually it is on but im catless so i figured it was for them.its idling at a grand for some reason,it was doing that before i put in the new o2's in i thought that would fix it i only had o2 codes last time i got it checked and havnt drivin the car since. im going to change the plugs,fuel filter and oil see if that helps any how would i go about dealing with water in my gas tank...could there even be any in it if my car is in the garage???
went to go start it this morning started right up, after a couple of mins of sitting there i heard some lifter tick or some noise similar so i shut it off. i started it back up and the noise was gone but then it started "resetting" itself again so i shut it off,go back to start it again and it just keeps cranking and cranking and smells like unburnt fuel. the first time i started it when it was running good it started to idle under a grand but sounded like it had a fatty cam and was going back and fourth 500-950 rpms.
has the car ben driven for a while after the LT's were installed? i had to constantly give my TA a little gas after the install to keep it running. may need a tune.
you might also want to check all your wiring and intake boots for loose connections or any signs of criters such as chewed wires, nests after the air filter. also chck for vacuum leaks and fuel pressure during cranking/running
battery voltage good? dont go off the gauge use voltmeter and maybe disconnect it for about 5 min to reset the PROM
just a couple ideas to try but cant diagnois anythng without a scan tool

as of right now its idling fine but bogs when i rev it im assuming bad plugs?? also oil pressure dropped down to around 30-35. i left it on for about 10 mins to make sure it wouldnt shut off and it did fine only "reset" once.
checked for bad wires/intake how to i check for vacuum leaks and bat. voltage? i dont know how long the long tube have been installed i got them with the car they have a good amount of surface rust so they have been there a while i guess
edit:forgot to add the tach still says its idling at a grand but it doesnt really sound like it is

Verdad Gallardo spray some brake clean or throttle cleaner around the base of the intake and the vacuum lines. pay close attention to how the engine reacts at certain spots. if it starts to idle smoother and you notice a difference then there is your vacuum leak 
. i wouldnt worry about the bat volt if your running for 10 min. but it kinda sounds like a fuel issue if it runs fine after letting a little gas out, could be bad gas
