No, It sounds like your timing is off or your firing order is wrong.
How to change the injectors on a 1990 4.5 liter Cad. ElDorado engine?
Yes, they all had 2 injectors on the v-6'sv8s and both v-6s. it was called a TBI system. (throttle body injection)
The intake manifold on a 1990 Acura Integra connects to the head of the engine. Loosen all of the nuts from the manifold to the head, disconnect the throttle body, vacuum lines, fuel injectors and coolant lines then pull the manifold from the head.
YesYes
firing order is1432
the firing order is 1342
1,3,2,4 that is the firing order.
No, 1990 1.6s are MPFI,(multi port Fuel injected) or fuel injected, and 1.5s are DPFI (dual point fuel injected) throttle body injected, they are completely different injectors, one motor has one for each cylinder, the other style has two for the whole motor, Injector cleaner can be used to clean injectors Searching for answers like this is much easier and faster from any search engine
