Having problems with your 1990 Cadillac Deville ?
Cadillac Deville surges and loss of power
\015 My 1990 Deville suges when it gets hot, and I lose power. Also when I try to down shift ("floor it"), it will not down shift and surges badly. Even when in park or neutral it does it. Any advice is greatly appreciated. PLEASE HELP.\015
I would first replace the FUEL FILTER. If problem persists, make sure exhaust is not partially clogged like a clogged catalytic converter. Hope this helps
