Okay Guys,
I need to know which is the best way to move forward. I have an 85 McLaren Capri with the dreaded CFI induction on it. It has mostly sat for the past three years because it is not reliable enough to drive. I am trying to decide if I should go Carb (keeps the stock look) or go full EFI from 86 up. I know that there are PRO's and con's to each. Mainly, I want the car to be driveable. If someone knows how to tune the CFI, or knows what the heck might be wrong with mine, I am all ears on that one also. The motor is an 85 roller motor...right? If I go carb, I would need an appropriate fuel pump, intake and carb, and new kickdown for the AOD. Do I need an new distributor? What else would I need? If I go fuel injected, I would need the intake, injectors, throttle body, fuel lines, and an 86 fuel tank (to work with the stock electronics). All of these parts are easily sourced from anyone who has done a HCI combo with the exception of the 86 fuel tank. It is my understanding that painless makes a wiring harness to adapt the CFI to true EFI. Has anyone tried that? I guess I would also have to move the battery if I go EFI because it is on the right side now. This is a really neat car and I enjoy driving it but right now it will just cut off without warning. As long as you are moving, it is fine. When you come to a stop, it surges and cuts off. The only way to make it stay running it to cycle the key 3 times. Then it will run solidly for another 15-30 minutes. I have replaced the TPS. I cannot find any other sensors and there is not any CEL. I am at my wits end but I do not want to let the car sit and rot any longer. Any help/advice is greatly appreciated.
Thanks,
Bryan
