I agree with rmay, crap from the tank may be part of your problem. A good carb rebuild with a proper soaking in cleaner to remove all the build up in the small passages might be required also. A full tuneup and you should be in good shape.

I love those body styles.

Thanks I will be cleaning the tank soon. The car has Fi. It seems like a fuel meetering problem to me. A friend who is a pro mech is going to take a look at it tomorow. I have replaced the cap, rotor, wires, plugs, fuel filter, vac lines. Everything I have done has improved the way the car runs. I dont want to just throw parts at it, I want to diagnose and fix the problem.

As soon as I saw your reply I thought "oh yeah, he said it was a first gen efi..." lol its late and my brain needs the carb soak!

it happens. It is hard to believe it has efi being an 84. The car was pretty cutting edge for its day, Efi, Irs, 225 tires, 14x7" wheels, overhead cam, Rack and Pinion steering, 4wheel disk brakes, anyway pretty awsome.

Btw Sometimes my brain needs a carb soak to.

28°btdc could cause alot of the problems I am having. It is now set @11, and the dizzy is off a tooth.

I noticed that after removing the ac condensor the car is running a bit cooler, without the fan it cools down @25-30 mph instead of 35-40 mph. The condensor was acting like a large radiator block. Also the radiator cap is bad.

Discovered this on Sunday. Signal wires from the dizzy to the ignitor coil.

This is how i fixed them. I folowed the plug and butt connected the wires together.

Well that will certainly affect your timing advance How's she running now?

[Sporty Modder]

She is running pretty good now, still has a bog with the throttle, calling it 95% right now.
Changing the plugs and wires(again)today to Ngk, w premium wires. I have Autolights in there now.

Probably a silly question, but are you gapping the plugs according to oem spec for the car? Also, are you doing fancy shmancy iridium, or just normal plugs? Some cars don't like iridium, and gap will affect how well it ignites.
When it bogs, is it running rich (like, really "bogging") or does it just lose power? You could also be blowing out the spark if your plugs aren't properly gapped. they're likely fine, but I thought I'd ask. Great find on those wires!

Thankyou for the question. Yes I am gapping them @factory spec @.32in.
