Replying to: phillyfrank (Jan 13, 2009 9:38 am) What was the date on one of the circles for the upper intake? If it was original to the car, it may have had a partial fix applied. I believe during 1999 is when GM changed the size of the metal EGR pipe. DexCool develops a gooop if regular antifreeze (old style) is added to it. If the original wasn't changed and there was air in the radiator instead of it being full, the DexCool breaks down and can become corrosive as well as gooey. You need to have the system flushed to remove the goop. But if you might be having intake work done, you should wait now. What you're really looking for is a seep somewhere other than the intake manifold to explain the coolant loss. That's better than replacing the upper and the lower gasket. For the turn signals, if both left and right kept going at the same speed, I'd vote for the flasher itself having died out. Since you say it slowly got slower that makes it more likely for my first check.

Air bag chims when driving. Have a 03 bonnie se sedan only owner it has been dealer serviced. The air bag light comes on when driving and chims. It has not been in an accident, but might have taken a speed bump to fast. Any one have similar problems. The waranty expired.

Replying to: charko2 (Jan 22, 2009 3:23 am) A new connector was required costing about $37. However, the real cost with this repair was the labor, since the dashboard has to be removed and the airbag system disassembled and reassembled. My dealer did the repair. Total cost: $375, also not under warranty.

Replying to: imidazol97 (Jan 16, 2009 11:51 am) In the 2nd pic there's something on the hoses at the bottom of the engine which looks like dex-cool. I'm bringing it to get inspected any day. I unhooked the battery to see if I could get the engine light off, but It didn't go off.

Replying to: phillyfrank (Jan 27, 2009 2:07 pm) The bolts around the UIM develope seeps which wick up oil and in some cases coolant which pools in the low spots such as around the bolt in the middle of the picture. The UIM is dry in that area so it's not going to seep them. The coolant goes through the UIM at the throttle body seals between it and the throttle body and about an inch to the left of that where the coolant goes from the metal lower into the ABS upper manifold. You're going to see external coolant in those areas if there are seal problems. The second picture shows a gooey clamp around the CV joint on the axle. Is it leaking grease--that's bad and needs to be check or fixed before joint fails. I see an orange brown tone on the belt and the pulley for the water pump. That suggests to me the water pump may be seeping; that's a wear item. When car's parked hot so coolant is under pressure you might be able to see a seep if you use a mechanics mirror to look into the backside of the water pump pulley there. The o-rings on the plastic elbow that comes out of the LIM to the idler housing may also seep in that area. You will be able to easily see brown coolant trail if that's occuring. |

My car doesn't start after it's been running awhile, but it starts great when it's cold. I know when the engine is going to run ok when it goes up to 3 or 4 rpms and it idles fine for awhile. When I go to start it, after it's been running it wants to stall, but if I tap the gas pedal (lightly) it will surge and not stall. Sometimes it seems like no gas is going to the engine. I took it to my mechanic and he says the fuel pumps pressure is low and needs to be replaced. Does this sound right? How can I replace it myself? How hard can it be? I can't afford to pay $300. I'm a carpenter and good with tools, but I never took the time to learn about cars.
