Real Fiero Tech

How'd we go from 3 to 4? That's a 33% increase in sample size with no accompanying info on the additional sample.

cant really use my C203 as i believe it was more the 3 injectors not working than that connector. If you remember correctly when i wiggled the connector it didnt make any difference and that car has ben sitting since like '92 or '93 and was completely untouched when i got it...

Hurray for Segways!

What's the scoop at the moment; any luck freeing up those injectors/replacing them? :salute:

i managed to free one of them up. The other two are pretty bad. Someone on Old Europe said he was gonna mail me a set for free this past monday. Not sure if he did or not and i dont really wanna bug him as not only are they free but he is even paying the shipping for me so...

Hopefuly they'l be here by this weekend and i can get 'er all figured out.

If he/she flakes out, I have a few spares on hand, also... But I'm buggering off on a trip next wednesday.

You can have 'em for cost of shipping; they worked when I last had the car running, but they MIGHT have that phantom-stalling problem. My new motor is a 95, so I upgraded anyway.

OK... got the injectors in. The car does run but it shoots to about 4K rpm and stays there. It takes a couple tries to get it started but it does start. Besides the 4K idle it seems to be making a ticking noise pretty good. If it was a SBC or something i would say a lifter....

I will try to get some videos but i dont have internet at home anymore so it prolly wont be for a few days atleast.

You've got a big vacuum leak.. do you have your brake booster line hooked up? EGR installed?
Even if the IAC is opened all the way I dont think you can get a 4k idle..

Sounds like you have a running car at least. It might be ticking a bit as it hasn't been run in forever and the lifters have bled down.

You def have a huge vacuum leak though. Take care of that and I bet you can go for a drive.

Yes, going from "unknown problem that prevents running" to "4K idle" is definitely an improvement.

well i couldnt find any vacuum leaks... Only hissing i hear at all was from the T.B. I stuck my hand over the opening and the idle dropped down to about 2500 but... I do not have an EGR, I just left the plug undone and made a blockoff plate where it used to sit on the intake (yes i checked it for leaks...)

Also found another problem. I am going to try to explain it best i can hopefuly i dont confuse you'all. On the transmissoin there are two "levers" one that go "up and down" (the one that moves when you wiggle the shifter forward and backward is if to go into gear) and then one that goes "in and out" (the one that moves when you wiggle the shifter left and right. Well the piece the makes the second lever go in and out is missing. Like there is suppose to be a C clamp or something that fits around the piece on the tranny....? Point being whatever is suppose to connect the shift lever to that piece on the tranny is missing. So it will only go into a couple gears unless i maunaly push in/pull out on the shaft.

you have a huge vacuum leak somewhere. Putting your hand over the tb should kill the engine.

An easy trick to help find a vacuum leak is to spray carb cleaner around gaskets and vacuum lines. The motor will stumble or idle differently for a quick second. I would plug the tb, and then spray the stuff around to help you find it. Its a huge leak, its there for sure, you just need to find it.

BRAKE BOSTER LINE! 2500 RPM with your hand over the throttle is ridiculous. Thats a big vacume leak.

Sorry, i didnt mean like completely closing off the T.B. If i flatten my hand against the TB it does die. I was just pushing my hand against it and controlling the amount of air that got in... I checked every port coming off of the intake manifold and i cant find a leak at all. There isnt any hissing or anything either (except from the T.B.)

if you are interested as i only get on the internet like once a week now...

Do you have a bunch of pics up somewhere?

I'm interested..

I've had a few requests for engine bay pics so i will try to get them up as well...

If you block the tb and the car dies, then there probably aren't any vacuum leaks at least not big enough to keep it running.

Perhaps the IAC is bad, or fully open causing the high idle because its allowing a ton of air to bypass it. Thats the only thing left that would cause that high idle. I wuold look into it.

I will check into that. Every sensor on the engine is brand new though so i dont know... Thing that pisses me off is that before the oil leak (distributor delete thingy) When Erik came up here it was running "fine". It idled fine and all that good stuff so i am just tryin to figure out what the hell is different now... Gonna try the ECM i used back then and see if that makes a difference at all...

Try, with it idling high, putting your finger over the IAC passage right before the throttle body. If it drops the idle, that's your problem.

And if it doesn't drop your idle when you do that... then "someone" messed with the throttle stop screw so your throttle stays open too far with your foot off the pedal.
