The trans am just got tuned and was super lean before and now is perfect. It ran like a champ on saturday and didnt start seeing problems till sunday. here is what happens.

When I try to crank up here is what will happen.
(A.) it will try for a prolong period (2-4 seconds before it rolls in), once it starts it wont idle good.
(B.) when I try to crank it up, it does nothing at all, doesnt even try. When the car does this, the dash resets but the odometer doesnt go back to zero, and the radio still has the current time on it. Also the battery still reads between 9-11V.

Either way when the car finally cranks its idle fluctuates a little more then it usually does. I am going to replace the spark plugs tomorrow and spark plug wires. That would not explain why sometimes it wont even try to roll over.

Thanks

 

Have you tried cleaning the battery terminals?

 

yes, but dont think its a battery issue because nothing resets in the car

 

anyone else think of anything?

 

I have had this problem briefly but it went away, i also read another thread that was similar. Post when you figure this one out as i can see it causing quite a headache.

 

I do not think this would be caused from tuning the car. Do you know what tuning software they used? I did tune mine once and after words when I followed a surtin sequence of events shutting the car down and getting out and locking the doors with the key fab it would set off my factory alarm. I posted on HP Tuners builiten board and asked what caused this and they said it was unrelated to the tuning. It continued until I did a flash entire later and then it never did this again. It might have been a glitch or a coincedence, i am not sure wich. I still think it would be something other then the tune.

 

It was tuned with EFI Live, they wrote over my HPTuners tune, I am pretty sure its not the tune. I am going to check tomorrow the connection to the battery terminal like what was suggested, then I am goin to change all 8 plugs and wires (they need it after what they have been put through the last 3 years) then change the oil tomorrow. If that doesnt work, I plan on reseting the bcm if that doesnt work I am goin to light the car on fire and collect the insurance.

 

ouch im confused by it..

 

Thats a good way to get out early with negative reports. Former STG2 here.

 

How do I check to see if its a security problem?

 

Did you just complete a head swap? If so, check the grounds on the back of the heads. They can do some screwy stuff with a loose ground!
