i have an 86 base model with emission removed. i just got it and its already giving me major problems. in 1st gear it bogs really hard when trying to accelerate. at any time. can anyone tell me what this is? or be of an help at all

 

In your intro post, you said the car has a 3" straight though exhaust. Besides being oversized for the car (2.5" is more than enough), an open exhaust on an S4 will render the auxiliary port actuators useless. The previous owner probably wired them open to get around this. The result is a big loss of torque under 3800 RPM.

You may also have problems with the emissions removal that when combined with wired open ports leads to poor driveability. It's difficult to say what exactly, but vacuum leaks are common, and a lot of people botch the removal process. You might want to find some of the many removal threads in the 2nd gen section, download the FSM, and get to work checking over everything that's been done to the car.

 

thanks man. i should also add it floods everytime i shut it off and im told theres a stuck open injector( possibly) but i have 4 stock ones i can fix this with if need be

 

Take a look at this thread for hot start info: https://www.rx7club.com/new-member-rx-7-technical-256/starting-problems-become-more-tricky-889110/. The link in there explains how to modify the injector duty cycle on hot starts. This will not work if the injectors are actually dirty enough to leak fuel.

 

so can i just remove the cold and hot start altogether?

 

ya you can but its the stock ECU that does that for a good reason

 

i want it too just stop flooding and run right so i can get to a job if i get one soon and save for a cosmo. i found a place that imports eunos for around 7500 so ya
