Runs But Will Not Idle

[1fast4]

I'm looking at a 1991 Eclipse GSX automatic with only 70,000 miles on it. The car runs but will not idle, I have been told that it is the turbo but I'm not sure. What should I look for to try and figure out if this is the problem or if it is something else? Please let me know quickly, I'm going to look at the car again monday and really want to buy it.

Thanks

well if it was me i wouldnt buy it cause its an automatic.as for the no idle,turbo has nothing to do with that.it can be a number of things.how much does he want for the car?

 

[skinnyt]

easy now the car may be worth the buy still, i got mine for $600 and it has 203468 miles on it and runs great...yea it has probs like ecu had to be changed($110) but im fixin it all up just so i can go fast and (1fast4) may be doin the same.u know.......we just all wont the same thing go fast or go home
still how much does he want for car ?

 

[1fast4]

The car is only $1500, so I think it is worth buying. It only has 70,000 miles on it and it has the service records from the dealership from 91 to 01. I dont care if its a auto, I would like a 5 speed but I need a new car my current one is dieing. Anyone know what could cause this, what I should look for? I'm not a nood to cars but I have zero experiance with turbocharged engines, and little with fuel injection.

Thanks

 

[skinnyt]

for $1500 thats not bad u can get the $ lower so buy it.its prob just senor gone bad.

 

[1fast4]

350s?

And I'm pretty much decided to buy it so if anyone can help me out with diagnosing/fixing the probem I would really appreciate it.

Please excuse any spellig, I have been drinking for hours.

Thanks

 

[skinnyt]

it miller time here too.but if u get the car for $1200 to $1300 maybe little more but not much get it .i got mine and im happy so what if have to work on it, thats why i got mine.to fix it all up looks and speed

 

[1fast4]

Bud here.

Someone told me it could be a cracked turbo manifold, could that be it?

What do I need to look for when I go back to look at it?

Thanks

 

[skinnyt]

well best thing to do is take a flash light and check the exhuast manifold u should see black lines in the manifold if its cracked but sometimes u cant thats the bs about that. then check hoses goin to turbo and to intake and other hoses connected to the main hoses i just talked about.if it all lookes good then u might have a senor prob or even a head gasket prob.thats all i can think of right now.theres just so many variables that could be wrong.

 

[1fast4]

Ok, thanks.

Maybe a little more info would help(I know this should have been the first post but I'm drunk).

I have driven the car, but it was about 2 months ago. When I drove you had to keep your foot on the gas for it to idle, once going it ran very well(and fast). It does not smoke at all, not when you crank it up or drive it(and I drove it pretty hard). I had a freind with me when I drove it, he stayed there whiile I was gone because the owner wanted to ride with me. He said he could hear a whistling noise when I was driving off(I couldnt hear it inside the car). My understanding was these cars are very quite, could it be a loose vacum line? Thats about all I can think of right now.

Thanks

check the air idle control motor.

 

[1fast4]

Where is it, how do I know if its bad? I have no experiance with these cars.

Thanks

The IAC, also called ISC, is located on the lower left side of the throttle body, and controls the idle speed. It is held on by 2 bolts and connects to 6 pin connector. It is likely that this the problem. To test it, measure the resistance between the 2 center pins and the pins on each side of it, a total of 4 readings. Resistance should be 28 to 33 ohms. If one reading is very high, the servo is bad. This is what it should look like. If that is all that is wrong with, I would buy it.

Make sure to ask when the timing belt was done and ask to see the receipts. It was due at 60k and your looking at $500-$800 to have it replaced. If it hasn't been done I won't spen more than $1000 for the car. Expect the exhaust manifold to be bad, eventually all the 1G manifolds crack. Expect to replace the studs when you put on a 2G manifold, that's another $150+ for parts. The ECU is likely to need new capacitors, if they haven't leaked and damaged the ECU that's only $30 to have done. Plan on changing all the fluids, that means oil, coolant, ATF, and brake. Another couple of hundred if you have a shop do it. What about the tires and brake pads? You could easily spend what you paid for the car just to address required maint. keep that in mind when your budgeting.

Yes, the timing belt replacement is an important issue. However, there was a timing belt recall for these cars. I believe that you can take the VIN number, from the car, to the dealer and find out if and when the timing belt has been replaced.

Geezus! How much does a timing belt cost? I'm pretty sre I can change it myself, cant be any harder than changing a timing chain on a saturn.

About the manifold, if it is cracked could that screw up the idle?

Automatic = :thumbdown

To give you an idea what's involved.

Not usually. Idle problems are usually Vacuum leak, ISC, Throttle Body, or ECU related.
Unless there is a more serious problem.

Here's what's involved in changing the manifold.

I went and looked at the car again today, the turbo definatly has to be replaced, its rattling very bad. But I'm still going to get it, I talked the guy into just trading the eclipse for my 93 Saturn SC1 that I'm driving right now.

I was wondering if I could put a 14b turbo on this car with no problems? Like would any of the lines have to be changed, would the stock injectors be ok?

BTW, I found the reciept for the timing belt change in the glove box with the rest of the maintance reciepts, it was done a little after 65,000 miles. Thanks for letting me know to look for that.

 

[1fast4]

So I need the bigger injectors from a manual? The only reason I asked about the 14b is because I know a guy thats got one pretty cheap with very few miles on it.

 

[1fast4]

Ok. They just drop right in, I dont need anything else?

Thanks

 

[herovueboi]

the injectors go right in but you should really think about using a www.dsmchips.com chip in your ecu or get a manual ecu. An SAFC would work very well also.

The Coolant return line and the return line Banjo bolt are different on the 13g. The other lines are the same. The part numbers you will need are:
Coolant return line 1G 14b turbo = MD117764
Banjo bolt 1G coolant return line 1G 14b turbo = MF650114

 

[1fast4]

Could I use the stock injectors until I can get the bigger ones?

I'm starting to think I just want a stock 13b, if anyone knows where I can get a used one let me know.

Thanks

I would not use the stock injectors w/o a fuel pump and on a 14b. side effects could be overheating, running lean or rich, and/or could blow you HG if your not careful. I have been in these stages for the past 2 months. The stock 13g is doable, just that you gotta find someone willing to sell their used ones. you could use www.dsmtrader.com and type in 13g and you might find some. you should becareful on that though, many people have been cheated on it, do it at your own risk. you should try the classified section of the forum also. I have a 13g turbo left over from my swap, but i still have to reconsider my situation. ask if you still need help on stuff.

 

[1fast4]

OK, nevermind about the stock injectors, I found some in the classifieds section. I think I found a 14b too.

If I get the injectors and the turbo I should be able to drive the car with just those right, I dont need a new fuel pump? Whats the dsmchips for? Will the stock ecu not run the bigger injectors properly?

I dont have much money to spend on it so a SAFC is out for right now, I just want to be able to drive it.
