I Have A 1991 Olds Trofeo With All The Extras On It . I Don't Drive It Much It Only Has 70,000 On It.It Ran Good Till Yesterday.I Drove To The Store And On The Way Back I Had To Get On It A Little Bit. First It Took Off And Then It Bogged Down Kind Of Like When Your Accelerator Pump Did Not Work Good On A Old Car With A Carburetor, Then 1 Second Later It Started To Take Off Then 1 Second Latter It Died And Would Not Run After That.I Checked The Codes In The CPU And This Is What I Got.
