Hello all just joined the forums for two reasons - one having many issues with my 03 chevy malibu and two this was the first result on google when i did a search for chevy forums...hoping to get a bit of help with my car...so here it goes:
What's going on? Well, I think the better question is, what isn't
going on? Here is a list of symptoms my car is experiencing:
1. Loss of power, i.e. won't go over 2,000 RPM
2. Loss of power, i.e. little acceleration due to #1 BUT it does accelerate and will, over time, gain enough speed to actually reach the speed limit.
3. Over heating - It's only over heat once since the problems started (I will give you a brief history after this list). The temp gauge seems to be very tempermental, by that I mean it will start to go up then swiftly go back down. Partially stuck thermostat?
4. Along with the above, the heat inside the car is not working.
5. Smoke (due to **** burning off the outside of the engine, possibly?) is coming from the hood. Source, I haven't a clue BUT I will show you pictures later in this thread.
6. There is what appears to be a vacuum line that looks as if its been snipped, not sure how long its been that way but again, will show pictures later in the thread.
7. There appears to be two coolant leaks, one on the left side of the engine and one on the right side of the engine. Pictures will be shown.
So, next I'll hit off on the history, this will explain maintenance and just general history and the timeline leading up to the issues:
1. Oil change very recently.
2. The air filter is BRAND new.
3. All of this started on the way to Lake Tahoe, CA on the 2nd of October. It over heated on the way up the mountain and leaked all of the coolant out through the over flow line. Prior to this there were NO issues with the car other than a flat tire which was a $10 fix (it was the stem).
4. It took us forever to get the car up the mountain and to the hotel but once we got it there we left it with the exception of taking it to the only shop that was open on that saturday. They supposedly ran a block test and said it would be $2300 to fix everything. We said to hell with it and took it back to the hotel and left the next day for our 1 hour ride back to Fallon, NV. The car didn't give us any issues on the way back down the mountain or the entire way home. When I say no issues I mean no over heating BUT the loss of power still existed.
5. Since we've been home I've been looking here and there for possible diagnoses but haven't really came up with anything myself. Got a check engine light and took it to Kragen and they ran their diagnostics on it and it said:
- EGR Valve
- Oil pressure switch
- Cylinder 3 misfire
6. I plan on taking the EGR valve off and cleaning it today, along with replacing the thermostat and the oil pressure switch (if i can find it on the engine).
So, now for some pictures:
This picture is showing you the vacuum line that is snipped or broken.
This is just an over head view of the entire thing, right below the oil cap in the middle-bottom of the image is where the smoke is coming from, you'll get a better understanding in the last picture.
This hose WAS leaking. I tighted the clamp on it and it seems to be good now.
This is the leak on the left side of the engine. You'll get a better view of WHERE it is in the picture below this one.
Okay, in the bottom-middle of the picture is the hose that WAS leaking, directly above that, in between the belts and the engine is where the leak is. In the bottom right corner of the image is where the smoke is coming from when the engine is running.
This picture is showing the right side leak. This is right by the thermostat housing.
If you need any other pictures or any other amplifying information please let me know. Thank you very much in advance.
