We have a 95 GST all-wheel drive turbo car . We swapped the original 2.0
for a different engine , we changed all the electronics to match the car.
Now the car idles great, but when you drive the car it shuts down around
4500 rpm, it acts like you are switching the key off and on. The engine is
getting plenty of fuel. has anybody encountered this problem any help would
be greatly appreciated
