96 civic cuts out on highway

Hi,

it sounds like there might be an issue with your breaks or breakpads sticking whenever you decelerate from high speeds. Try "pump breaking" or applying the breaks for short bursts of time in order to slow down to see if this dodges the issue. If so, I would still get the break pad or system checked while still mentioning the full issue to the technician. Thank you.

check fuel pressure and change TPS (throttle position sensor)

cadilatic convertor

sounds like a fuel filter(cheap and easy) or a partial melted catalyic converter(expensive)

ANY DTC'S ?
CHECK ENGINE COOLANT TEMP. SENSOR 2 WIRES YELLOW / BLACK
SHOULD BE ON INTAKE NEXT TO THEMOSTAT (V8)

change the fuel filter, put in some gas treatment

it could be that your car came out of time a little or you need a tune up

Check Main computer harness or computer itself 12vdc and ground check computer harness is far from exhaust manifold, sometime it loose, touch it and produce fails Check with an anlog VOM the +5vdc on one of the pins or TPS or MAP. it swing? bad pc check all vacuum connectors, from 96 to today, those hoses have 13 years and may be toasted Check CGR valve Scan must show any error when car cut off, follow trace to the fail check fuel pump pressure and gas filter

Check the fuel filter it may be blocked.

try changing the coil packs
