96 formula help Hello to all first off, secondly i just recently purchased a 96 formula m6 with 80k and its been sitting for about a year in storage. When i get the car above 3500 it cuts out and dies. It atleast takes another 10 or so tries to get it running and the check engine light comes on when the car dies. I was wondering if anybody could tell me what might be wrong? Thanks

The guy that i bought the car from is an auto mechanic and he said not too recently he replaced the opti and the water pump. The other thing is the car will start up run, but once you shut it off it wont restart for about another 45 min to an hour
Take the ICM and coil off and have them tested at your local AP store. Also, get the codes scanned that will tell you right away as one of them might be a "DTC16 - Low Resolution Pulse" (Opti code) you never know as even a new opti can go bad or have been installed wrong. Start with the codes and post them up.

Verdad Gallardo Time for a new opti as that is the "low res" code from the opti. Also, your water pump is on it's way out and you need to do that at the same time. Very common on our lt1s to have the water from a bad wp take out the opti. I got the wp from your pm btw. Let me know if u need any advise or help as u can easily do both yourself.
R U sure where it's leaking at the WP? Posssibly a loose hose on the WP or upper radiator hose neck? Get under there with it running and see if you can see where the leak is coming from. If it's coming out of the weep hole (hole at the bottom of the wp) then the WP is bad and needs to be replaced. The OPTI def needs to be replaced, but now check everything to make sure the WP is not bad too.
NOOOOO - find a good inpependent mechanic in your area and have them look at it. The dealer is gonna rape you.
If not then where are you? Call around some shops or google a good mechanic in your area and look for good feedback/reviews? Then call them to see what their knowledge is on LT1's. Might be time to start learning your car and the LT1 more as it's a very easy motor to get to know and they are getting older so more maintenance is gonna be required.
^x2 This fix can be performed by any competent mechanic for half the cost. Instead of towing etc, take a good look at your motor, check some how to sites (Installuniversity? etc) and maybe you can tackle it with help from a buddy?
