Hopefully a 1st gen whiz can help me out here, Ive got a buddy whos looking to sell me his 1st gen. Cosmetically its flawless. He said the problem with it is whenever it get warmed up, it dies. Is this a common easily fixable problem? Sounds to me like its a stuck choke. Its an 81. My daily driver just lost oil pressure and threw a main bearing so im looking for a replacement asap.

Need more info. HOW does it die? Is it a carburated model (with a choke ****) or a GSL-SE (fuel injected)? Does it run fine until the choke **** retracts, then quit? Or does it run fine, then slowly the revs drop off to zero while choke is still pulled? Or does it run fine after choke retracts but then quit when you let up on the gas to stop at a traffic light? Does it re-start easily after it dies? Does the problem go away after the car has been warm for 15 mins to 1/2 hr? Finally, is the car bone stock or does it have aftermarket ignition and/ or fuel system components? I'm sure one of us can help if we have all the details.

Sounds to me like the idle was adjusted while cold. It probably just needs a tune-up.

Properly running engine will tend to rev higher once warmed up, not lower, so if idle was adjusted while cold, it would only rev higher once wamed up, but nice try Sterling.

I agree however that a tune-up, i.e. idle mix, idle speed and TIMING adjustment is probably what it needs.

what rpm does it idle at when you start it back up...Mine does the same...I just had to do the idle and a/f screws until it got up to about 800rpm or so.....Before, I was idling at around 200<sigh>

smnc

Ummmm... no?

Cold idle should be LOWER than warm idle... unless I've been into the cheep Crack again...

My wife's S model idles arond 1800 when cold and 800 when warm...

My GSL-SE idled around 2k when cold and 600 when warm... Before the engine died....

So you make it run super rich so it runs like a champ when its cold and you think its going to have a HIGHER idle when its warmed up from being really rich??? Nice try cdrad51

cdrad51

lol well my car, if I start it up and let it idle, will begin at 700 rpm or so. By the time is fully warmed up, it will be 850 or so.

cdrad51

I'm talking about idle adjustment, not mixture adjustment.

hornbm

yeah idle MIXTURE, thats what sterling is talking about. If the guy made it run really rich by tuning it when it was cold so it ran really good, it'll run like crap when its warmed up.

cdrad51

Oh Ok, my bad then. I thought when Sterling said "the idle was adjusted when cold" he was refering to the idle speed, not mixture.

I agree with sterling unless there's a ignition component breaking down or a intake leak that's not happening until it gets some heat.

its cool

NOOB!!!

Carlos starts another pissing contest and winds up pissing on his shoes again.
I knew I wouldn't have to say anything once you edited in the smilie face, my bitch!

I went to check it out today, and we couldnt even get it to turn over. Another guy there said he couldnt get it to start the last three times hes tried. We put a jumper box on it and still nothing. I told him to call me if he can get it to turn over, atleast then I can test the compression. If he calls me I can report back about when and how it dies etc. The way he makes it sound is that it doesent run after its warm, but I dont know.

TonyTurboII

Imnot sure how it acts when its started. I went over there to check it out, and some other guy was there. He said it hasnt started the past three times hes tried when other people came to look at it, and when we tried today it wouldnt even turn over. So im going to call my pal and tell him if he can get it to turn over Ill come back. Atleast then I can test the compression and get an idea wether or not its worth buying. The engine and bay are so clean its amazing, I wonder if the motor has been rebuilt. Theres a Rotary performance sticker under the hood, but its their old number.

Stupid double posting POS.

I actually edited it to change "adjust" to "adjusted", and then as a side thing dropped in a smiley.

Alright, I just picked up a 82, and it has the same problem, but i will go into more detail...

when you start the car it idles around 1800 rpm, once it warms up and the rpms fall below 1000 it dies. as long as you give it gas it will stay running. and what i had to do on the drive home is to pull the choke when coming to a complete stop, to avoid left foot braking.

would the idle mixture be off?

this is originally a california car, so it has all the emissions junk installed, could that be the culprit?

I went out to check the idle speed adjustment, but it doesn't seem to be located where the manual states. above the mixture screw is a vacum line. again is this because of the CA Emissions?

idle speed is to the right of the a/f screw. Kinda hard to see it. Sounds like vacuum leak. Could be bad adjustment of carb also, like you were saying

Thanks, i found it... The hayne's manual couldn't be more wrong...

I adjusted the mixture, and have it idliing steadlily @ 1k. the mixture screw was turned all the way in.

it's not perfect, but good enough to last until i can afford to have a professional set it. I don't like messing with carbs, unless they say Edelbrock and are mounted on a Chevy V8
