Advance Auto sells the harness. $44

I'm going to try and save my harness.

Update.

I was able to save my harness for the distributor, and got it ready to go back in the car.

The harness came out a little short, and the plastic piece that keeps the wires in place is broke and off the distributor.

The Vacuum Advance that comes with the distributor is also remanufactured, and is taking awhile to work properly.

I dipped the gear at the end of the distributor in some extra motor oil I had, and installed it.


The Good News.

My Starion started right up without fail.

I took it around the block a couple of times, and once it got to a proper operating temperature, I decide to give it some gas.

The car pulls pretty strong, and this was the first time in a long time that it was able to redline (6,500 rpm).


Concerns.

I can hear, and slightly feel a ticking or knocking. But very, very, very, subtle.

Engine sounds a little louder. I think it's cleaning itself out from when I drove it last. At one point before I did the work, it was back firing, and wouldn't accelerate.

I don't know if I needed to lube the distributor other then the gear at the end.

Today is a hot day, but seemed to me like the heat on the engine was getting a little hotter then what I'm comfortable with.

Last but, not least.

The car does not die, but when I accelerated, and let off the gas, the rpms got really low, and then would pick back up to normal.

I had a garage checkout the timing before. I might have to take it back to check it again, with the new distributor and vacuum advance.

Any thoughts?

I'm also waiting for a new O2 Sensor. I will install it tomorrow when it arrives.

I think I have to let it run for awhile, and let the car do it's thing.

I will take the car to the garage this week to check timing.

It almost sounds like the sound is coming from the distributor?

Update.

So I found out what was causing the noise that seemed to be coming from the distributor.

It was the distributor rotor rubbing on the distributor cap.

I replaced the 02 sensor, and haven't taking the car to the garage to check timing.

What could cause the rotor to rub on the cap?

This may seem simple as crap, however, make sure that your battery, alternator and ground are properly tight, clean and working. Old stock alternators usually suck and don't put out. Less electricity means less performance no matter what you do downstream of that. I learned that lesson once.

Wrong part or it's not correctly seated. Keep in mind the ppl behind the desk at your local car parts store and the company they work for usually don't deal with cars like ours. These are quasi rare.

Thank you Anthonytsi!

Update.

It turns out the distributor was poorly rebuilt by someone and never tested it to see if it worked! I now installed the new distributor and new cap, took it to my local garage to check timing, Good News Garage (if you listen to NPR on Sundays).

The car was 20 degrees off!

The car still drops in RPMs when you let off the gas, but it's not as bad as it was.

I took it on the highway, gave it some gas, and the car was running like a champ!

I reached 100 mph with ease. I did a take off as if I was racing and the car spun the wheels 1-2nd gear and chirped them on 3rd.

This came at a cost. It turns out that one of the hoses in the back of the engine broke and started leaking antifreeze. I pulled over to let it cool down since the temperature started rising.

Next on my to do list.

I need to get that hose that goes on the back of the engine.

Maybe reset my TPS/ISC.

It almost felt as if the car was getting better the more I drove it, but will see how that goes once I get that hose in.

Hope this helps.

I'll keep updating.

OK!  Maybe Last Update.

As I said before. I was going to replace the heater hose, and reset the TPS.

My Starion is all stock except for the BOV.

I replaced the heater hose on the car, and decided to turn the car on, to check for leaks (No Leaks).

The car still struggled to idle properly, so I started to look for things that might be causing the idle to suffer, TPS/ISC, Throttle/Cable, Wires, and Vacuum Lines.

It turned out to be the BOV! I put my hand over the BOV, and there was air coming in, and out.

When I had my hand over the BOV the engine idled fine. BOV was hooked to Port #2 (Right Port Closer To Firewall) on the throttle body.

I turned the car off, removed the BOV from any vacuum lines, and Voilá! The car idled fine!

I drove the car around, and everything seems to be working fine.

The BOV is not connected to any lines. I think it's still leaking a little bit through the BOV.

Results

The car seems to be running fine for now. Never restarted the TPS.

It seems that the car does redline, but doesn't seem to go any faster at redline.

It seems slow to redline, or not at all on 3,4,5, gear.

I do need to take care of the exhaust part of the engine. I suspect there maybe exhaust leaks.

I want to remove the BOV and have it all stock for now.

What do you guys think?

Car seems fine. Throttle seems very responsive, and power seems to come on right away(only at low RPMS).

BOV is disconnected, but I would like to get rid of it.
