get it scanned at your local parts store, once we know the code that set the CE light on we will know what the fix is

sounds like fuelpump check valve or regulator not holding residual pressure you need to check if fuel pressure is holding with engine off approx. 40 psi

Have you checked the power steering belt and the fluid level in the power steering reservoir? The belt may be slipping or the hard turn may have caused a leak in one of the hoses that power the unit.

I suspect the idle solonoid and/or the automatic choke Idle somonoid plays havoc when cold and you have to keep playing with the revs to keep it running. Even though you had cleaned the mas airflow sensor it still may be faulty. I would take it to Orielys or Autozone and ask them to read the codes for you {no charge} this will eliminate the guess work, good luck

im sorry but i dont think you are going to able to find that chip.i think your best choise would to go the the junk yard for a new amp.or if you feel lucky try conntacting bose.

Replace cat converter, check with gm dealer for warranty. I had replaced a many.

Hi GENO, if you can take your car to the neatest auto parts store they will check it for you for free, but it will be nice to buy the parts for a thank you. BEST OF LUCK

Autozone

how did you come to that conclusion

May need a new alternator

Is it going dead while it's being used or when it's parked?

Did you ever get this fixed? I have the same issue! Thanks.

With numerous shop visits,I don't like
to even suggest anything --BUT --

I would be almost certain, that the fuel pump
is worn & binding up & the shops, as strange &
sad as it sounds,do not know how to test it

I would check the oil filter. They may have left the old gasket on which will leak.
