its jus running like **** he past few weeks im loosing a ton of power im sure it jus needs a tune but i get the power when the car wants it like monday i was messing with my dad and could barley pull on his toyota and then 20 min later it pulled on c5 zo6 its crazy how the power jus comes and goes but when i hit the gas to pull from my dad it back fired and hesitated

You should take this guys advice

Trying to make sense of this thread... 6-10mpg? seriously what are you running a 4:56 spool? my 94 vert gets mid 20's with a 3:73 rear. Its just a car, figure out the issue and fix it or pas it along like the person who neglected the 94 I just picked up. Photos and a description always helps good luck

just went up to my uncles and he is going to take me up to his friend to have the car tuned he said it is going to be a huge difference when its done with power and milage hope he's right he also gave me a set of c6 rims with spacers so happy

Do tell, who is tuning a 95 LT1 for you?

El Gatto

twin turbo 3 rotor would be more fun

not even close so the majesticness of a single'd 2jay

a 2jay can be pretty bad-ass, especially with a gigantic turbo

I am wondering the same thing.

im guessing he just means tune up... plugs, wires, filters, ectttt

i know but i jus found a 2002 z28 with 63k loaded up with t tops for 8

LS1s are superior in every way and run 10s stock I heard.

lol jus think that something stock would have a lot less problems and i know the ls1 is a lot better with gas and i really did want t tops instead of a vert

Def, LS1s really don't have any issues and they run forever.

i did all new plugs wire ... act with the new motor down to the water pump and opti so i don't see it being that but it is running really rich my uncle said the he has a guy in westchester that did his vette

the motor it has is a lt1 the cylinders were honed out a little to clean up the walls it the only real mod is the gm hot cam other then that it has roller rockers and lifters new pistons and new heads that i believe are stock maybe jus milled down a little bit

and i got a high of 12.168 that was 80% high way

Yup.

**** it, I'm too tired. All the pieces are there, figure something out.

also it back fired a few times (at least sounded like it loud boom noise) and at low rpms like when i coast to a light the engine light comes on and usually turns off after i get it to a decent speed and higher rpm and also the car runs a lot hotter around town like 185 highway and 210 around town anything sound weird with that my idle is very low around 550 while in drive about 750 in neutral but is usually fine at idle jus a lot of weird things with the car that don't add up to me i know that the car is untuned and is running very rich and has a small cam in it but it shouldn't be half the milage as NHRABill said his gets mid 20' i get between 6-12 but usually around 10

On a serious note, you do realize none of that will change without you working on teh car or bringing it to a reputable shop.... right?

You keep repeating it needs to be tuned, call up PCMforless, order a mail order tune, and then do all the misc tune up stuff pointed out earlier.

Otherwise, continue making random posts about its short comings, buy an LS1 and then wonder why that car doesn't run great either.

something has to be a miss. I had a carbed 383 with a 650 lift cam in it with a turbo 350 trans and that got better than 10 MPG so something is wrong

You have a lot going on.

Sounds like you need to get the car on a scanner and see what's up. Could be a whole myriad of things. Bad plugs, dirty MAF, bad O2s, vacuum leak, etc etc.

Buy a thirdgen. Problem solved.

What, since its a third gen, when it doesn't run its normal so no problem?

:lol:

^^^^ ouch

I think you'll be alright, use that nice tax free deployment money and get yourself a newer Vette
