#355 of 1365 Nubira check engine light
Sep 12, 2005 (8:36 am)
Problem: 2000 Nubira CDX Wagon, bought new 9/2001 in Twin Falls, ID. Now has 58,500 miles. 16,950 mi CEL came on and engine idled too high and tranny shifted hard from P to Drive: TPS replaced (warranty). 19,110 mi same symptoms and problem (now 11/2002 and no help from Daewoo Tech Support); problem eventually resolved itself. 22,670 mi same story. GM dealer in Boise couldn't fix, problem resolved itself again (gradually tranny would get better, engine revs back to normal, and eventually CEL went out). 34,433 (now 01/2004) SAME PROBLEM! GM dealer diagnosed TPS again, replaced under warranty. Problem solved for about 2 WEEKS! 34,919 you guessed it! Dealer replaced throttle body & gasket (warranty). Said "intermittent throttle body shaft binds, remove and replace t-body." This seemed to do the trick. 47,367 CEL on again but no other symptoms. Local mech couldn't find any problem. 54,029 (now 03/2005) CEL again (like a recurring nightmare!). GM dealer said "sensor A-heated lambda (?), O-2 sensor circuit". Cost me $413 to R&R. Dealer also checked Camshaft Position Sensor per recall, said OK and did not replace.
My goal was to get it running and get rid of it. CEL problem reappeared two months ago but again resolved itself and has been okay for last four weeks, no problems. Sold it last week for $4K, included full disclosure of warranty work and O-2 sensor replacement. THE DAY AFTER THE BUYER PAID AND TOOK THE CAR, she called in a panic: CEL on, engine idling way too high!!!!! Told her I would take care of getting it fixed at my expense.
HELP!! What can the problem be? GM dealer has been very good but can't seem to solve the problem. Is the car still under any warranty: < 60,000 miles, < 5 years? BTW, I didn't know about this website and the excellent forum until last Friday. I read all 354 posts but can't seem to find anything on point. Also, is the "timing belt - tensionner - rollers - water pump" repair covered under warranty? I never knew there was a problem with them, never had them replaced. Same thing with the A/C drain hose/wet floor problem -- is that Nubira too or just Lanos & Leganza? Time is of the essence, as the buyer is bringing the car overy tonight for me to take it to the dealer tomorrow (dealer will only cover repair work done < 12 months ago if it's still in my name).

If your mechanic charged $4000 for the repair then he is a thief. You can get a complete engine head from ebay for $300 from a Cylinder head company called CCH.

I would suspect the high idling is due to a sensor that is related to air flow. Mass flow sensor, Map sensor.
And yes you need to do the timing belt service ASAP. at 54K miles is pushing it.
The recommended interval is 55K miles, but I have heard of it failing earlier. What goes bad is the tensioner then the water pump. So you need to replace or advise the owner to replace the timing belt, tensioner, rollers, water pump.
And yes Daewoo should cover those under warranty if < 60K. If the maintenance is done properly, these cars can go for a very long time. I have already seen ones with over 200K miles.

Took the Woo to GM dealer on 9/13. They couldn't find anything wrong (the CEL had gone out, of course). I had them do a fuel injector cleaning and new fuel filter; the tech said clogged filter was probably the culprit. I asked her about replacing the tensionner/ timing belt/ rollers under warranty. She said Daewoo will not pay for warranty repair if the parts haven't failed. They wanted to charge me $150 just to pull the timing belt cover and check it out. I opted not to, but told the buyer they really need to be alert to any suspicious sound coming from engine compartment, could be the timing belt deteriorating. Buyers seemed OK with that. Hopefully, I've seen the LAST of the Woo.

I am having the same problem. I can take it our of park if I stick something in the "shift lock" hole next to the transmission. WHat part is this and where can I get it? Is it possible I don't need a new one at all?? Please advise...
#361 of 1365 Lanos wont start cold.
Sep 17, 2005 (5:06 pm)
I have a 1999 Lanos, my car when it's cold has trouble idling and stalls. Once it stalls it just turns over. i think i have a similar problem to post #350. I do know when it just turns over, that i have to wait at least 30 - 45 seconds until i hear a faint tick in the dash, then it will try and start, before the tick, forget it, just turns over. Once my car is at running tempreture it's all a-okay. Also, at how many kilometers should i do the timing belt.
the daewoonator needs help! Thanks in advance!

The culprit is the brake release switch which is found right behind the break pedal from the top. When you press the brake the switch closes and makes contact and the gear lock or latch is removed. This is a safety so you cannot shift out of park without pressing the brake pedal. It is a $10 part and you can replace it yourself.
Sometimes the switch is not completely broken and is just stuck in the depressed position. Try pulling on its tip outwards all the way, and then put it back and see if it works again.

hesitation during idling in the morning:
1. Clean fuel injectors.
2. Clean throttle body.
3. Replace fuel filter.
With the lanos it might also be an electrical problem. I heard that it is a common problem that AC drain hose leaks water inside the car which damages some wiring to the engine computer. Lift the carpet and check for any water damage.
From what you are saying with the faint tick, sounds like electrical issue.
Timing belt should be replaced every 50K miles together with the tensioner and rollers.
#364 of 1365 Nubira SE 2000 Won't Start (sometimes)
Sep 20, 2005 (11:16 am)
I recently got a Nubira SE 2000. It has just under 70k miles on it. It drives fine and operates normally (some A/C compressor issues in the summer) most of the time. In the past month it has refused to start on me twice. Both times it was parked on a downward slope but I have also parked it on the same slope (my driveway) for weeks in-between without a problem. Once, te gas tank was 1/3 full, and once it was 3/4 full. The engine turns but there is no ignition.
The first time it happened I had it towed to a mechanic who found nothing wrong with it (it started as soon as he tried)... Any suggestions?
