Engine Gurgling..??
yeah... my engine is gurgling.... haha thats the only way I can describe it. It used to only happen in short bursts while engaging or disengaging the clutch, but it now the "gurgles" come and go at idle too, sometimes for a few minutes. I cant figure out where its coming from at all!! it seems to be right infront of the steering wheel, yet Im not exactly sure where...
my TPS is crapping out too, so maybe that has something to do with it? i doubt it, but its a thought.
and lastly, although <u>i mainly would like to know about the gurgling</u>, i dont think this is worth starting another thread over so im adding this question here too:
when i turn on my lights, my fan, my radio, etc... anything that uses electricity, my rpms drop (if at idle) quite a bit and those other things lessen (for exaple: lights on, add fan, lights dim. or fan on, add lights, fan slows). is my alternator going out as well? or is that normal? i only ask becuase it seems to be getting worse and worse.... Thanks guys

1. gurgling
A) Maybe that sound goes from water pump or liquid runing in radiator? Check anti-freeze level in radiator - ON COLD ENGINE (best - in the morning) turn off radiator cap (BE CAREFUL!!! there can be pressure and antifreeze can be sprayd from there - so cover radiator cap with a rag and turn it off slowly. Make sure there is enough liquid.
2. RPM drop
how far RPM drop?
When I run engine at idle, than turn on lights, A/C, rear window defoger, fan (at 4) and both window raisers. RPM drops and lights dim. It's ok, It happens because those devices consume big current.
Check is this happens when RPM is 1500-2000.
And check (best at night) - turn on lights and rev up engine from idle till 2000-3000 RPM and see if light become brighter.
Use voltmeter to measure voltage at idle and at 2000-3000 RPM - should be around 14V

the gurgling sound is the odd one.. on that I cannot be sure if it is really water gurgling or something mechanical. However, you heater is inside the car with you, so it could be coolant flowing through that.
Lights dimming and such. If you say it is getting worse, I would look hard at your battery. If it is not holding the charge it once was, the alternator has to work harder, putting a load on the engine at idle. If your alternator was going, it would be putting less of a load on the engine.
